Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE The following summarizes the relationship between our CEO’s, and our other NEOs’, total compensation paid and our financial performance for the fiscal years shown in the table (in this discussion, our CEO is also referred to as our principal executive officer or “PEO”, and our NEOs other than our CEO are referred to as our “Non-PEO NEOs”):

(1) | Mr. Maheswaran was our CEO for each of the three fiscal years included in the table above. For fiscal year 2021, our Non-PEO NEOs were Messrs. Chukwu, Beauchamp, and Fulton, and Norris Powell, our Senior Vice President and Chief Human Resources Officer. For fiscal year 2022, our Non-PEO NEOs were Messrs. Chukwu, Beauchamp, Fulton, and Silberstein. For fiscal year 2023, our Non-PEO NEOs were Messrs. Chukwu, Ammann, Beauchamp, Silberstein, Fulton, and Chang.
(2) | See the Summary Compensation Table above for detail on the Summary Compensation Table total compensation for our CEO for each fiscal year covered in the table. The average compensation for the Non-PEO NEOs for fiscal year 2023 was calculated from the Summary Compensation Table above. The average compensation for the Non-PEO NEOs for each of fiscal years 2022 and 2021 was calculated from the Summary Compensation Table as disclosed in the Company’s Proxy Statement filed with the SEC in calendar year 2022 or 2021, respectively.
(3) | For purposes of this table, the compensation actually paid (also referred to as “CAP”) to each of our NEOs (including, for purposes of this table, former named executive officers who are included in the Non-PEO NEO group for the applicable year) means the NEO’s total compensation as reflected in the Summary Compensation Table for the applicable fiscal year and adjusted for the following with respect to each NEO:
| • |  | Less the amounts reported in the “Stock Awards” and “Option Awards” columns of the Summary Compensation Table for the applicable fiscal year,
| • |  | Plus the fiscal year-end value of Semtech option and stock awards granted in the covered fiscal year which were outstanding and unvested at the end of the covered fiscal year,
| • |  | Plus/(less) the change in value as of the end of the covered fiscal year as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and were outstanding and unvested at the end of the covered fiscal year,
| • |  | Plus the vesting date value of Semtech option and stock awards which were granted and vested during the same covered fiscal year,
| • |  | Plus/(less) the change in value as of the vesting date as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and vested in the covered fiscal year,
| • |  | Less, as to any Semtech option and stock awards which were granted in prior fiscal years and were forfeited during the covered fiscal year, the value of such awards as of the end of the prior fiscal year,
| • |  | Plus the dollar value of any dividends or other earnings paid during the covered fiscal year on outstanding and unvested Semtech stock awards (no dividends or dividend equivalents were paid or credited with respect to Semtech options or stock awards during the applicable fiscal years),
| • |  | Plus, as to a Semtech option or stock award that was materially modified during the covered fiscal year, the amount by which the value of the award as of the date of the modification exceeds the value of the original award on the modification date (none of the Semtech option or stock awards held by the NEOs were materially modified during the fiscal years covered by the table).
| In making each of these adjustments, the “value” of an option or stock award is the fair value of the award on the applicable date determined in accordance with FASB ASC Topic 718 using the valuation assumptions we then used to calculate the fair value of our equity awards. For more information on the valuation of our equity awards, please see the notes to our financial statements that appear in our Annual Report on Form 10-K each fiscal year and the footnotes to the Summary Compensation Table that appears in our annual Proxy Statement.
The Pay Versus Performance table above reflects the CAP (determined as noted above) for our CEO and, for our Non-PEO NEOs, the average of the CAPs determined for the Non-PEO NEOs for each of the fiscal years shown in the table. The following table provides a reconciliation of the Summary Compensation Table Total to Compensation Actually Paid for our CEO.

(4) | Semtech TSR represents cumulative total shareholder return on a fixed investment of $100 in the Company’s common stock for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. Philadelphia Semiconductor Index TSR represents cumulative total shareholder return on a fixed investment of $100 in the Philadelphia Semiconductor Index (“PHLX”) for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last three fiscal years against the Company’s total shareholder return and the total shareholder return for the Philadelphia Semiconductor Index (each calculated as described above) over that period of time.

See Exhibit A for a reconciliation of non-GAAP operating income for fiscal years 2022 and 2023 to the most directly comparable GAAP measures. We consider non-GAAP operating income to be a key metric in our executive compensation program, used in determining the fiscal year 2023 annual bonuses for our NEOs. See the Compensation Discussion and Analysis section of this Proxy Statement for more information regarding the use of this performance measure in our executive compensation program. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last three fiscal years against the Company’s non-GAAP operating income for each of those years.

See the Compensation Discussion and Analysis section of this Proxy Statement for more information regarding the use of these performance measures in our executive compensation program. In addition to the financial performance measures listed above, the Company views its stock price, upon which the value of all of the equity awards granted by the Company is dependent, as a key performance-based component of its executive compensation program in order to further align the interests of the Company’s senior management with the interests of the Company’s shareholders. |  |
