It is designed for fast switching applications requiring a forward voltage drop of 790 mV at 2 A and a reverse leakage of 1 µA at 100 V. Typical uses include polarity protection, freewheeling diodes in DC-DC converters, and output rectification in low-voltage power supplies where the junction temperature can reach 175°C. The 2 A average rectified current (Io) is the continuous forward current the diode can handle in a typical half-wave or full-wave rectifier circuit. The 100 V reverse voltage (Vr) sets the maximum DC blocking voltage — adequate for 48 V or 60 V bus rails with margin. The fast recovery spec of ≤ 500 ns at > 200 mA means this Schottky switches cleanly in low-frequency PWM or line-frequency rectification; it is not a hyper-fast diode for MHz-level converters, but it avoids the reverse-recovery losses of a standard PN diode. The 790 mV forward drop at 2 A is typical for a 100 V Schottky in this current class — expect higher drop at elevated junction temperatures. ## DO-221AC SMA Flat Leads — footprint and reflow notes The SMA Flat Leads package (DO-221AC) is a low-profile surface-mount variant with flat leads — no J-bend or gull-wing. It sits flush on the PCB, which helps with thermal transfer to the board copper. The supplier device package is SMAflat Notch. Reflow profile follows standard lead-free solder profiles; MSL level is not specified in the record, so treat as MSL 1 unless the reel label indicates otherwise.","metaTitle":"STPS2H100AFN Schottky Diode, 100 V 2 A, SMA Flat Leads","metaDescription":"STPS2H100AFN Schottky rectifier: 100 V reverse voltage, 2 A average current, fast recovery ≤500 ns.
