Single-Phase 250V 0.8A Silicon Bridge Rectifier WOG Package
Condition
Unused New Old Stock. Looks unused. Silver-plated leads show light tarnish as visible in photos. Lead legs are slightly bent from loose storage but can be straightened without much effort. Visual inspection OK. Sourced from a maker's workshop collection that was cleared out.
Ships same business day. Reliable parts since 1999. Honest pricing, no nonsense.
Product Overview
General Semiconductor B250C800 is a single-phase silicon bridge rectifier designed for low-power AC to DC conversion. Housed in the classic WOG circular package, it provides 250V RMS input capability and 0.8A average forward current. The B250 designation reflects the 250V RMS rating, while C800 indicates 800mA current capacity.
This through-hole rectifier features four radial leads: two AC inputs (~) and positive (+) and negative (–) DC outputs. With a peak repetitive reverse voltage of 600V and strong surge handling capability, it remains suitable for vintage equipment repair, small power supplies, and legacy European-designed circuits.

Frequently Asked Questions
What do the four leads represent?
Two leads are AC inputs (~), and the remaining two are positive (+) and negative (–) DC outputs.
What voltage can this handle?
It is rated for 250V RMS input and 600V peak repetitive reverse voltage.
What current is it rated for?
The maximum average forward current is 0.8A at 25°C ambient, with proper thermal conditions.
Is the tarnish on the leads a problem?
Light tarnish on silver-plated leads is common for vintage stock. Leads can be cleaned or lightly tinned before soldering to ensure good wetting.
Is this interchangeable with W06G?
Higher-current bridges like W06G may substitute electrically in some designs, but this B250C800 matches original 0.8A specifications for period-correct repairs.
Before compact SMD bridges, rectification was handled by parts like this—simple, rugged, and easy to service. If your board calls for a classic WOG bridge, this one keeps the footprint and the era intact.
