Product details

The STPS2545CT is a dual Schottky rectifier from STMicroelectronics, housing two 45 V, 12.5 A diodes in a common-cathode configuration inside a single TO-220-3 through-hole package. The fast recovery time — ≤500 ns at >200 mA — makes it suited for high-frequency switching supplies, output rectification in DC-DC converters, and freewheeling diodes in motor drives. The common-cathode arrangement simplifies PCB layout for center-tapped transformer secondaries or dual-output rails where the cathodes share a common node.

No last-time-buy notice or NRND flag is in effect, so it remains a safe choice for new production BOMs.

Frequently asked questions

What is the difference between STPS2545CT and STPS2545?

The STPS2545CT is the common-cathode dual-diode version in a TO-220-3 package. The base number STPS2545 typically refers to a single-diode variant; the 'CT' suffix indicates the dual common-cathode configuration.

Is STPS2545CT RoHS compliant?

Yes, the STPS2545CT is rated ROHS3 Compliant.
