B772 Specs and Replacement

The B772 is a PNP bipolar junction transistor commonly used in low-frequency power amplification and switching applications. Built in a SOT89/TO126 package, it supports a collector-emitter voltage of 30V and a collector current up to 3A, making it suitable for moderate-power stages. The transistor offers a DC current gain typically between 60 and 320, depending on the selected grade, ensuring efficient amplification with low drive requirements. With a power dissipation of about 0.5W and good thermal stability, the B772 is often paired with its NPN complement D882 in push-pull audio output stages. Its rugged construction, reliable switching behavior, availability make the B772 a practical choice in consumer electronics, motor drivers, regulated power supplies.
