200 V blocking, 1.5 A continuous — the rectifier for a 120 VAC bus
The W02G-E4/51: The W02G-/51: The Vishay W02G-/51 is a single-phase bridge rectifier in the standard WOG through-hole package, rated for 200 V peak reverse voltage and 1.5 A average rectified output current. The 200 V blocking rating comfortably handles a 120 VAC input with margin for line transients, while the 1.5 A continuous current covers typical low-power DC supplies, small motor drives, and auxiliary bias rails.
At 1 A forward current the maximum forward voltage is 1 V, which translates to about 1 W of conduction loss per amp — within the thermal budget of the WOG package when mounted with adequate copper area. Reverse leakage is specified at 5 µA at the 200 V peak reverse voltage, a low enough figure that it won't affect efficiency in most designs, but worth checking if the rectifier sits on a high-impedance bus where leakage could pull down a bias rail.
ROHS3 compliance is confirmed, so it meets current EU and global environmental requirements without an exemption expiry.
