PMBTA45,215

Single Bipolar Transistors Overview

The PMBTA45,215 is an NPN high-voltage low VCEsat transistor manufactured by Nexperia USA Inc. It operates in a SOT-23 surface-mount package with three terminals. Key electrical parameters include a collector-emitter voltage (VCEO) of 500 V and a collector-base voltage (VCBO) of 500 V. The device supports a continuous collector current (IC) of 0.15 A and a peak collector current (ICM) of 0.5 A. DC current gain (hFE) ranges from 50 to 100 at IC = 30 mA and VCE = 10 V. Total power dissipation is rated at 300 mW at Tamb ≤ 25 °C. Junction temperature limits extend up to 150 °C.
