Product Details

BD234 PNP Power Transistor - 2A/45W Switching & Amplification

The BD234 is a PNP power transistor in a TO-126 package, rated for 45V and 2A, commonly used as the complementary counterpart to NPN power devices in push-pull amplifier and driver stages. It's a solid choice for hobbyists building audio amplifiers, motor drivers or power-switching circuits that need a compact, easy-to-mount PNP power device.

Functions & Applications

PNP Power Device: Complements NPN power transistors in push-pull and H-bridge topologies.
TO-126 Package: Compact power package that can be fitted with a small heatsink for improved thermal handling.
2A Collector Current: Enough headroom for motor drivers, relay banks and audio output stages.
45V Rating: Suitable for low-voltage power supply and battery-powered projects.

Frequently Asked Questions

Q: What is the complementary NPN transistor for the BD234?
A: The BD234 is typically paired with the BD233 or BD235 NPN power transistors in complementary push-pull configurations.

Q: Does the BD234 need a heatsink?
A: For currents approaching 2A or extended operation near its 25W rating, a small TO-126 heatsink is recommended to keep junction temperature safe.
