Product details

80 V, 15 A dual Schottky in a through-hole I2PAK

Forward drop and thermal budget at 15 A

At 15 A per diode, the maximum forward voltage is 790 mV — that's about 11.85 W of conduction loss per diode at full tilt. The reverse leakage at 80 V is 40 µA, which climbs with temperature but stays manageable for most power-converter designs.

Recovery speed and switching behaviour

Listed as a fast-recovery Schottky with recovery time ≤ 500 ns at > 200 mA — typical for a 15 A Schottky in this voltage class. That's fast enough for 50–100 kHz switching supplies; above that, the reverse-recovery charge starts eating into efficiency, and a SiC or GaN diode would be a better fit.

STMicroelectronics has ended production, so new stock is not available through the factory or authorised distributors. Sourcing is limited to independent distribution — surplus inventory, new-old-stock, or broker-sourced lots. No official successor has been published by ST.

Frequently asked questions

Is the STPS30SM80CR obsolete?

Yes, the STPS30SM80CR is listed as obsolete by STMicroelectronics. Production has ended, and the part is only available through surplus or broker channels.

What is the replacement for the STPS30SM80CR?

STMicroelectronics has not published an official successor for the STPS30SM80CR. For a pin-compatible replacement, look for a dual common-cathode Schottky in I2PAK with 80 V reverse voltage and 15 A per diode — parts like the STPS30L80CR (if still active) or an equivalent from another manufacturer may fit, but verify the forward voltage and thermal specs against your design.

What are the specifications of the STPS30SM80CR?

It is a dual Schottky rectifier with common-cathode configuration, 80 V reverse voltage, 15 A average rectified current per diode, 790 mV maximum forward voltage at 15 A, 40 µA reverse leakage at 80 V, fast recovery ≤ 500 ns, and a 175°C maximum junction temperature. Package is TO-262AA (I2PAK) through-hole.
