Product details

45 V, 15 A per diode — common-cathode Schottky pair

The STPS3045CG-TR: The forward voltage drops to 570 mV max at 15 A, which keeps conduction losses manageable in a power supply or OR-ing circuit. With a 200°C maximum junction temperature and fast recovery under 500 ns, this diode array handles high-frequency rectification in switch-mode power supplies and DC-DC converters without thermal derating concerns at moderate loads.

D2PAK footprint and board integration

The tab is electrically common with the cathode, so the layout must account for that when pouring the ground or output rail. The common-cathode pair means both diodes share the same cathode terminal — ideal for center-tap full-wave rectifiers or as a dual OR-ing diode where the cathodes tie to the same output rail. The anode pins are separate, so each diode can be driven independently.

Active lifecycle and compliance

ROHS3 compliant, so no restricted-substance exemptions to track for EU or global BOMs.

Frequently asked questions

Where can I buy STPS3045CG-TR and check current availability?

Sourced through independent distribution channels.

What is the closest functional alternative to STPS3045CG-TR?

The STPS2045CG-TR is a lower-current sibling — same 45 V reverse voltage and common-cathode D2PAK package, but rated 10 A per diode instead of 15 A. It drops into the same footprint and layout if your load current fits within the lower rating.

What compliance documentation does STMicroelectronics provide for STPS3045CG-TR?

The part is ROHS3 compliant. Standard STMicroelectronics documentation includes the datasheet, RoHS declaration, and REACH compliance information — available on request.
