Rectifier Bridge PB 151 M 1.5A 50V

The Rectifier Bridge PB 151 M is a single-phase full-wave bridge rectifier rated at 1.5 A and 50 V. It combines four diodes in one component with four terminals, so it turns the AC output of a transformer into pulsating DC in a single part, ready to be smoothed by a capacitor. It suits small low-voltage power supplies, chargers and repair work.

Rectifier Bridge PB 151 M Specifications

• Type: single-phase full-wave bridge rectifier
• Maximum reverse voltage: 50 V
• Average forward current: 1.5 A
• Terminals: 4 (two AC inputs marked ~, plus + and − DC outputs)
• Internal structure: 4 diodes in a bridge configuration

Rectifier Bridge PB 151 M Applications

• Small linear power supplies with a step-down transformer
• AC to DC conversion for low-voltage relays, LEDs and controllers
• Polarity protection, so a DC input works whichever way it is connected
• Battery chargers and adapters
• Repair and replacement in consumer electronics

What's in the Box

• 1 × PB 151 M bridge rectifier, 1.5 A 50 V

Tip: The peak of an AC voltage is about 1.41 times its RMS value, so keep the transformer output well below 35 V AC to stay inside the 50 V rating. Expect a drop of roughly 1.5–2 V across the bridge, because the current always passes through two diodes.
