PDTA144ES,126

Overview

The PDTA144ES,126 is a PNP resistor-equipped transistor from the PDTA144E series manufactured by NXP USA Inc. It integrates two bias resistors (R1 and R2) with a typical value of 47 kΩ each into a single component. The device operates within a collector-emitter voltage range of -50 V and supports a DC output current up to -100 mA. It utilizes a SOT54 (TO-92) plastic through-hole package with three leads: base, collector, and emitter. The unit features a maximum total power dissipation of 500 mW at 25 °C ambient temperature and a junction temperature limit of 150 °C.

Feature Summary
