The 550 mV forward voltage at 1 A is the conduction loss per amp — low enough to keep the junction temperature under the 150°C max in a typical 1 A continuous load, but the 10 µA reverse leakage at 30 V means the diode will self-heat more than a PN junction in high-temperature environments. ## Switching speed — why the 500 ns recovery matters In a 12 V to 5 V buck converter running at 200 kHz, this diode handles the catch current cleanly. The 30 V blocking margin is enough for the reflected voltage on the secondary side of a flyback supply up to about 24 V input. ## Package and footprint — DO-214AC (SMA) reality The SMA body is a standard footprint — same as the SS12, SS14, and dozens of other 1 A Schottkys. The cathode band is on the body; the tab is the cathode. For 1 A continuous, a 1-inch square of 1 oz copper on the cathode side keeps the junction temperature within the 150°C max at 25°C ambient. Derate above that per the datasheet curve.","metaTitle":"STPS130A Schottky Diode, 30V 1A, DO-214AC (SMA) – Active","metaDescription":"STPS130A Schottky rectifier, 30V reverse voltage, 1A forward current, 550 mV Vf at 1 A.
