Dual 15 A Schottky in a TO-262 I2PAK — what you're getting
The STPS3030CR from STMicroelectronics is a dual common-cathode Schottky rectifier rated for 30 V DC reverse voltage, with each diode handling 15 A average rectified current. Forward drop sits at 490 mV at 15 A — low enough to keep conduction losses manageable in a 30 V rail. The pair shares a cathode in a single TO-262AA I2PAK through-hole package, so it replaces two discretes in a center-tap or OR-ing configuration on the same footprint.
ST lists the STPS3030CR as current-production, active status.
Package reality: through-hole only
This part ships in a TO-262-3 I2PAK with long leads — a through-hole package. No surface-mount variant exists in this order code. If your reflow line needs an SMD footprint, you're looking at a different STPS family member. The I2PAK body handles the thermal mass of 30 A total continuous current, but board-mount is wave-solder or manual insertion, not pick-and-place. Shipping form is tube, not tape-and-reel.
Fast recovery classification — what the <500 ns rating tells you
Classified as Fast Recovery with trr < 500 ns at > 200 mA forward current. The rating confirms it's a switching diode, not a 50/60 Hz line rectifier. Use it in the 50–200 kHz range typical of PFC boost stages, output rectification on a flyback, or OR-ing in a redundant 24 V supply. The 30 V Vr ceiling limits it to low-voltage rails; don't push it into 48 V bus OR-ing.
