The forward voltage drops to 520 mV at the full 7.5 A load — that 520 mV figure is the conduction loss floor per diode at rated current, so the total thermal budget for the DPAK package is the sum of both diodes' losses plus the tab-to-ambient thermal resistance. ## DPAK surface-mount — footprint and reflow Housed in a TO-252-3 (DPAK) package with two leads plus the tab, the STPS15L45CB is a surface-mount device. The tube shipment means the parts arrive in a rigid anti-static tube, not a reel; plan for pick-and-place with tube feeders or manual placement. ## Fast recovery — switching speed for the secondary side Listed with a recovery time of 500 ns or less at forward currents above 200 mA, this Schottky is fast enough for 50-100 kHz switching power supplies and output rectification stages. The 500 ns ceiling is a datasheet maximum; typical Schottky recovery is much faster, but the 500 ns spec guarantees the diode clears the reverse recovery window in hard-switched topologies without excessive ringing.","metaTitle":"STPS15L45CB Schottky Diode Array, 45 V, 7.5 A, DPAK","metaDescription":"STPS15L45CB dual Schottky rectifier, 45 V reverse, 7.5 A per diode, 520 mV Vf at 7.5 A.

The STPS15L45CB offers a 45 V Vr(max) — 5 V more headroom — which matters if the secondary-side rail sees transients above 40 V.
