Product details

The STPS30L45CG-TR is a dual Schottky rectifier from STMicroelectronics, configured as a common-cathode pair in a D2PAK surface-mount package. Each diode is rated for 45 V reverse voltage and 15 A average rectified current, giving the pair a combined 30 A capacity in a single footprint.

Forward voltage is 550 mV maximum at 15 A per diode — this is the conduction loss number you plug into the thermal model. Reverse leakage is 400 µA at 45 V and 25 °C junction. Leakage roughly doubles every 10 °C rise, so at 125 °C it can reach tens of milliamps — a factor to include when sizing the heatsink or when the diodes are paralleled for higher current.

Package and mounting — D2PAK layout notes

The D2PAK (TO-263-3) has two leads plus a tab — the tab is the common cathode. Surface-mount only — no through-hole option.
