ONSEMI BDX33BG Power Transistor

The BDX33B and BDX33C (NPN) along with BDX34B and BDX34C (PNP) are high-performance Darlington complementary silicon power transistors designed for low-speed switching and general-purpose applications. Featuring high DC current gain of approximately 2500, these devices support collector-emitter voltages up to 80V or 100V, respectively. They include built-in base-emitter shunt resistors, are Pb-Free, RoHS compliant, and capable of dissipating up to 65W. Suitable for power switching in various industrial and electronic systems, these transistors ensure reliable operation with excellent thermal stability and safety margins.
