Product Overview
Westinghouse 1N3288A high-power silicon rectifier diode housed in a heavy-duty DO-8 (DO-205AA) stud-mount package. Rated for 100 V peak repetitive reverse voltage and 100 A to 150 A average forward current, this component handles demanding industrial rectification tasks, high-surge power conversion, and equipment maintenance. Features a solid threaded base stud for direct heatsink installation and a heavy flexible braided lead terminating in a flat lug terminal for secure wiring.

Frequently Asked Questions
What mounting package does this rectifier use?
This diode uses an industry-standard DO-8 (DO-205AA) stud-mount package with a heavy flexible braided top lead and a flat terminal lug.
What hardware is included on the stud?
Each unit includes the hex nut and washers fitted onto the threaded mounting stud.
What is the peak reverse voltage rating for the 1N3288A?
The 1N3288A is rated for 100 V peak repetitive reverse voltage (VRRM) and can handle forward surge currents up to 2,500 A.
Built for an era when power conversion was measured in pounds of copper and bolted directly to aluminum heat sinks. For heavy current that demands serious metal, this Westinghouse stud rectifier is ready to get back to work.
