STTH1002CB

STTH1002CB Description

The STTH1002CB from STMicroelectronics is a high-performance dual common-cathode diode array designed for fast-recovery rectification in power electronics. Rated for 200V reverse voltage (Vr) and 8A average rectified current (Io) per diode, it features an ultra-low reverse recovery time (trr) of 25ns, making it ideal for high-frequency switching applications. With a forward voltage drop (Vf) of just 1.1V at 5A, it minimizes conduction losses, while its 175°C max junction temperature ensures reliability in demanding environments. Packaged in a DPAK (TO-252) surface-mount format, it combines robustness with ease of assembly.

STTH1002CB Features

• Fast Recovery Performance: Optimized for ≤500ns recovery, reducing switching losses in high-frequency circuits.
