PBSS5240ZX

Single Bipolar Transistors Overview

The PBSS5240ZX is a PNP low VCEsat Breakthrough In Small Signal (BISS) transistor manufactured by Nexperia USA Inc. It operates with a collector-emitter voltage of -40 V and a continuous collector current of -2 A, supporting peak currents up to -3 A for pulses under 1 ms. The device utilizes the BISS technology to achieve high energy efficiency through reduced heat generation. Key electrical characteristics include a maximum collector-emitter saturation resistance of 320 mΩ at -1 A collector current and -100 mA base current. The transition frequency is specified at 150 MHz, and it features a total power dissipation capability of up to 1 W depending on mounting conditions.
