Description
Product Details

BD132 PNP Power Transistor - 3A, 15W TO-126

The BD132 is a PNP power transistor housed in the TO-126 package, designed to handle up to 3A of continuous current and 15W of power dissipation. It is widely used as the PNP half of complementary push-pull audio amplifier stages and in medium-power switching or motor-driving circuits.

Functions & Applications

3A Continuous Current: Suitable for driving motors, relays and medium-power loads directly.
15W Power Dissipation: Handles moderate heat loads, especially with a small heatsink attached.
TO-126 Package: Compact power package with a metal tab for easy heatsink mounting.
PNP Complement: Pairs naturally with the NPN BD131 for symmetrical push-pull amplifier designs.

Frequently Asked Questions

Q: What is the complementary NPN transistor for the BD132?
A: The complementary NPN part is the BD131, which shares the same voltage, current and power ratings in the same TO-126 package.

Q: Does the BD132 need a heatsink?
A: For currents or dissipation approaching its 3A/15W limits a small heatsink is recommended, since the TO-126 package has limited surface area for heat dissipation on its own.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
