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.
