Product details

Forward voltage is 460 mV maximum at 10 A per diode. Reverse leakage is 800 µA at 25 V.

Dual common-cathode — layout and thermal reality

The 1 Pair Common Cathode configuration means the two anodes are independent, and the shared cathode is the exposed tab of the TO-263 package — the tab must be connected to the output rail and to a copper plane for heat spreading. The fast recovery characteristic (≤ 500 ns at > 200 mA) is typical for Schottky diodes.

The base product number is STPS20, which covers a family of 20 A Schottky rectifiers with different reverse voltage ratings; the 25 V variant is the lowest-voltage, lowest-Vf option in the series.

Frequently asked questions

Is STPS20L25CG RoHS compliant and lead-free?

The STPS20L25CG is listed as RoHS compliant and lead-free per STMicroelectronics' standard product declaration. The TO-263 package uses matte-tin plating on the leads and tab.
