About this product
The RB154 is a single-phase silicon bridge rectifier rated for 1.5 A and 400 V, housed in a molded plastic case with silver-plated copper leads. It converts AC input into pulsating DC and is designed for mounting on printed circuit boards, such as in small power supplies and adapter circuits.

Frequently asked questions
How do I wire the RB154 in a circuit?
Connect the AC supply to the two AC pins and take the DC output from the + and - pins. Check the polarity marking on the body before soldering.
Can it be used with a 220 V mains supply?
Its 280 V RMS and 400 V peak reverse ratings cover a 220 V AC input. Keep the DC load below 1.5 A, and add a heatsink or reduce the load if you operate close to that limit.
