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.
ABSOLUTE MAXIMUM RATINGS
February 2003
For PNP types voltage and current values are negative.
