Its key parametric is a forward voltage of 430 mV at 1 A — this is the conduction-loss floor for a 1 A Schottky, directly relevant for low-voltage rectification where every millivolt of drop eats into the output rail margin. Listed as Fast Recovery with trr ≤ 500 ns at forward current >200 mA. That speed is adequate for line-frequency rectifiers and low-frequency switching converters (e.g., 50–100 kHz flyback secondaries), but not for MHz-range synchronous rectification where a SiC or GaN diode would be needed. The junction temperature ceiling is 150°C, so the thermal design must keep the junction below that under steady-state load. ## STmite Flat — package and footprint reality Housed in a DO-222AA (STmite Flat) surface-mount package. The package accepts standard reflow profiles; no special moisture sensitivity level is flagged in the listing. ROHS3 compliant. No last-time-buy or PCN notices are in effect for this order code. For a production BOM, this part presents no supply-chain risk from discontinuation.","metaTitle":"STPS1L20MF Schottky Diode, 20 V, 1 A, STmite Flat","metaDescription":"STPS1L20MF Schottky rectifier: 20 V reverse, 1 A forward, 430 mV Vf at 1 A.
