At 30 A continuous, the dissipation is 26.1 W, which demands a heatsink sized for the junction-to-case thermal path. The junction temperature ceiling is 150 °C, so the heatsink must keep the case temperature low enough to stay within the SOA at the ambient of the enclosure. ## Fast recovery — why it matters in switching circuits The fast recovery spec (≤ 500 ns above 200 mA) means the diode switches off quickly when the voltage reverses — reverse recovery charge is low, which reduces switching losses and ringing in a hard-switched converter. For a 30 A Schottky, the recovery time is inherently short because there is no minority-carrier storage; the ≤ 500 ns figure confirms it behaves as a majority-carrier device across the full current range.","metaTitle":"STPS30SM100ST Schottky Diode, 100V 30A TO-220, Fast Recovery","metaDescription":"STPS30SM100ST Schottky diode, 100V reverse, 30A average, 870mV Vf at 30A, fast recovery ≤500ns.
