COMPLEMENTARY PNP - NPN DEVICES

DESCRIPTION

The BD433, BD435, and BD437 are silicon

epitaxial-base NPN power transistors in Jedec

SOT-32 plastic package, intented for use in

medium power linear and switching applications.

The BD433 is especially suitable for use in

car-radio output stages.

The complementary PNP types are BD434,

BD436, and BD438 respectively.
