Product details

45 V, 12.5 A per diode — the thermal budget anchor

Each Schottky diode in the common-cathode pair is rated for 12.5 A average rectified current at a forward voltage of 570 mV typical at that current. Reverse leakage is specified at 125 µA at the 45 V reverse voltage rating. Leakage rises sharply with temperature; at sustained high junction temperatures the leakage contribution to self-heating needs to be factored into the thermal derating.

Dual common-cathode in a single D2PAK

The two Schottky diodes share a common cathode connection (pin 2 and the exposed tab), with the anodes on pins 1 and 3. This configuration is a direct fit for center-tapped secondary rectification, OR-ing diodes in redundant power feeds, or as a freewheeling pair in a half-bridge leg — all in one surface-mount package instead of two discrete parts.

Frequently asked questions

Is STPS2545CG obsolete?

Yes, STMicroelectronics lists the STPS2545CG as Obsolete. No official replacement part number has been assigned.

What are the specifications of STPS2545CG?

It is a dual common-cathode Schottky rectifier rated 45 V reverse voltage, 12.5 A average rectified current per diode, with a forward voltage of 570 mV at 12.5 A. Reverse leakage is 125 µA at 45 V. Maximum junction temperature is 175 °C. Package is D2PAK (TO-263-3), surface mount, supplied in Tube.

What is STPS2545CG's listed speed?

The device is classified as Fast Recovery with a recovery time ≤ 500 ns at a forward current > 200 mA. This is typical for a Schottky barrier diode — the fast switching is inherent to the Schottky junction, not an epitaxial fast-recovery structure.
