1.5 A, 1 kV — the board-level rectifier for bulk AC-to-DC conversion
The W10G-E4/51: The Vishay W10G-/51 is a single-phase bridge rectifier in the 4-Circular WOG through-hole package, rated for 1.5 A average rectified output and 1 kV peak repetitive reverse voltage. It converts AC line voltage to a pulsating DC bus in unregulated power supplies, battery chargers, and appliance control boards where the 1 kV reverse rating provides margin for 240 VAC mains with line transients.
Thermal and electrical margins for continuous duty
Reverse leakage is 5 µA at the 1 kV rated voltage, so standby power loss in a continuously-mains-connected circuit is negligible.
Active production, ROHS3 — sourcing posture
Vishay lists the W10G-/51 as an active product with ROHS3 compliance, meaning no planned end-of-life notice and full material declaration for EU and global markets.
