BCX52-16TF

Overview

The Nexperia BCX52-16TF is a PNP power bipolar transistor housed in an SOT89 (SC-62) surface-mounted plastic package. It supports a collector current of -1 A and peak currents up to -2 A, with a maximum collector-emitter voltage of -60 V. The device offers a DC current gain range of 100 to 250 at -150 mA. Thermal resistance from junction to ambient varies based on PCB copper area, ranging from 250 K/W in free air to 114 K/W with a 6 cm² pad. Total power dissipation reaches 1100 mW under specific mounting conditions.
