PDTC144ET-QR

Overview

The PDTC144ET-QR is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia, housed in a small SOT23 (TO-236AB) surface-mounted device plastic package. It integrates bias resistors to simplify circuit design and reduce component count. The device features a collector-emitter voltage of 50 V, an output current capability of 100 mA, and a typical input bias resistor (R1) of 47 kΩ with a ratio of 1. Qualified according to AEC-Q101, it supports operation across a temperature range from -65 °C to +150 °C.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce pick and place costs
