BDX34B PNP Darlington Power Transistor (80V, 10A, 70W, TO 220, 1 Qty)

The BDX34B PNP Darlington Power Transistor is a high gain silicon bipolar transistor designed for power switching, amplification and electronic driver applications. Featuring a collector base voltage rating of 80V, maximum collector current of 10A and collector power dissipation rating of 70W, this transistor is suitable for audio power amplifiers, motor control circuits and industrial electronic equipment.

The BDX34B features a Darlington configuration consisting of two internally connected PNP transistors, providing high current amplification with relatively low base drive requirements. Its minimum DC current gain of 750 under specified test conditions makes it suitable for controlling higher current loads using appropriate driver circuits. The TO 220 package supports through hole PCB mounting and heat dissipation with a suitable heat sink. Its complementary NPN transistor is the BDX33B, making it suitable for complementary power amplifier and switching configurations.
