GBU808 800V 8A Bridge Rectifier

GBU808 8 A 800 V Glass-Passivated Bridge Rectifier – GBU Package

The GBU808 is an 8‑amp, 800‑volt glass‑passivated single‑phase bridge rectifier in a through‑hole GBU package. It provides reliable DC output in AC-to-DC conversion applications like SMPS, motor control units, and power supplies. With a low forward voltage drop (~1 V per element @ 4 A), it helps minimize power loss and maintain efficiency.

This bridge rectifier supports high surge loads up to 200 A and features low reverse leakage (~5 µA @ 800 V). Its molded plastic construction meets UL 94V‑0 flammability standards, and it is RoHS-compliant with lead‑free finish. Operating temperature spans from −55 °C to +150 °C.
