STTH30S12W

STTH30S12W Description

The STTH30S12W from STMicroelectronics is a high-performance standard recovery diode designed for demanding power electronics applications. This through-hole-mounted device features a 1200V reverse voltage (Vr) and 30A average rectified current (Io), making it suitable for high-voltage, high-current circuits. With a fast recovery time of ≤500ns (typical trr = 50ns) and a low forward voltage drop (2.9V @ 30A), it ensures efficient switching and minimal power dissipation. The diode operates within a wide junction temperature range (up to 175°C) and complies with ROHS3 and REACH environmental standards, ensuring reliability in harsh conditions.
