20 A Schottky in a TO-262 – what you need to know
The STPS20SM60SR is a 20 A, 60 V Schottky rectifier from STMicroelectronics, packaged in a through-hole TO-262-3 (I2PAK). It carries a fast recovery spec of ≤500 ns at >200 mA, a forward voltage of 630 mV at the full 20 A rating, and a reverse leakage of 85 µA at the 60 V reverse maximum. The junction temperature ceiling is 150°C. This is a standard Schottky for medium-current, moderate-voltage DC rails – think secondary-side rectification in switch-mode power supplies, output OR-ing diodes, or freewheeling clamps in motor drives and inverters where the through-hole I2PAK package gives a direct thermal path to a heatsink or chassis.
STMicroelectronics lists the STPS20SM60SR as obsolete. We source and quote each order against an RFQ, confirming availability and current pricing at the time of quotation. No factory lead time applies – the channel is spot-market, so the procurement decision turns on what the market holds at the moment you commit.
