The forward drop is 490 mV max at the full 1 A rating. ## Forward drop and leakage — the two numbers that decide the fit At 490 mV Vf at 1 A, this diode sits in the typical range for a 20 V Schottky in this current class. The reverse leakage is 3.9 µA at 20 V. The recovery spec — <500 ns at >200 mA — confirms it is a fast Schottky. ## Package note — STmite Flat footprint The DO-222AA (STmite Flat) is a proprietary ST package — not a standard SOD-123 or SMA footprint. If you are replacing a failed SS12 or similar SOD-123 diode, the pad layout is different. Check the board copper before committing; the STmite Flat has a smaller body but the pad geometry is unique.","metaTitle":"STPS120MF Schottky Diode, 20V 1A, STmite Flat Package","metaDescription":"STPS120MF Schottky diode: 20V reverse, 1A forward, 490 mV Vf at 1 A, 3.9 µA leakage.
