GBU8J-T is a single-phase diode bridge rectifier designed for 50/60 Hz mains rectification and power supply applications. It features four diodes in bridge configuration with a maximum alternating input voltage of 420 V RMS and a repetitive peak reverse voltage (VRRM) of 600 V. The device delivers 8 A average forward current with a forward voltage drop below 1.0 V at 8 A, and exhibits a reverse recovery time of approximately 1500 ns. With a junction temperature rating up to 150°C, thermal resistance of 19 K/W (junction to ambient), and UL recognition (File E175067), the GBU8J-T is well-suited for commercial-grade power conversion applications requiring reliable rectification with minimal heat dissipation.
