Product details

Device identity and key ratings

The GBU6K-E3/51: The Vishay GBU6K-/51 is a single-phase bridge rectifier in the standard GBU through-hole package. It delivers 3.8 A average rectified current and is rated for 800 V peak reverse voltage. The 800 V peak reverse rating suits it for 240 VAC line rectification with margin for mains transients. Forward voltage is specified at 1 V max at 6 A, so conduction loss at the 3.8 A average is well under 4 W.

Temperature range and package

The GBU package is a 4-pin SIP with a standard 5.08 mm pitch, easily hand-soldered or wave-soldered into a PTH layout.

Listed as Active with ROHS3 compliance.

Frequently asked questions

What is the GBU6K-/51's reverse leakage current at rated voltage?

Reverse leakage is 5 µA at 800 V peak reverse. This is a typical value for a standard-recovery silicon bridge at 25°C; leakage doubles roughly every 10°C junction rise.
