Product details

Dual Schottky in D2PAK — 45 V, 10 A per diode

Forward voltage is 550 mV maximum at 10 A, and the switching speed is rated as fast recovery (≤500 ns, >200 mA).

45 V reverse — headroom for 24 V and 36 V rails

The 45 V reverse voltage rating provides a solid margin on 24 V and 36 V DC buses, covering transients and ripple without derating stress. Reverse leakage is 200 µA at 45 V — typical for a Schottky of this current class, but worth noting if the diode sits in a high-temperature ambient where leakage doubles per 10 °C rise.

Frequently asked questions

What are the specifications of STPS20L45CG-TR?

It is a dual Schottky diode array with a common-cathode configuration. Reverse voltage rating is 45 V, average rectified current is 10 A per diode, forward voltage is 550 mV max at 10 A, and reverse leakage is 200 µA at 45 V. Switching speed is fast recovery (≤500 ns, >200 mA). Package is D2PAK (TO-263-3) for surface-mount assembly.

What is the difference between STPS20L45CG and STPS20L45CG-TR?

The -TR suffix indicates Tape & Reel packaging, which is the standard format for automated surface-mount assembly. The base part STPS20L45CG typically ships in tube or bulk. Electrically and mechanically they are identical — same die, same D2PAK package, same ratings.
