The ZVP0535B is a high-efficiency, high-voltage, dual-channel NPN transistor manufactured by Plessey. It has a maximum voltage rating of 50 Volts and a maximum current rating of 5 Amps. It has an internal emitter resistor network and is ideally suited for power amplification, switching, line regulation and other high-power applications. Its large collector dissipation (100 Watts) makes it suitable for variety of applications. Its excellent noise immunity, low Vcesat and low saturation voltage make it an ideal component for high-density circuit designs. The ZVP0535B is in a TO-3 package, making it very easy to mount on the board.
