PDTC144ES,126

Overview

The PDTC144ES,126 is an NPN resistor-equipped transistor from the PDTC144E series manufactured by Philips Semiconductors (NXP). It integrates bias resistors R1 and R2, both typically 47 kΩ, into a single component. The device is housed in a SOT54 (TO-92) plastic single-ended leaded package with three leads. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, a DC output current (IO) of -100 mA, and a total power dissipation of 500 mW at 25 °C ambient temperature. The thermal resistance from junction to ambient is 250 K/W.

Feature Summary

Integrates built-in bias resistors to simplify circuit design
Reduces component count and board space requirements
Eliminates external resistor components for switching applications

Applications

General purpose switching and amplification
Inverter circuits
Interface circuits
Circuit driver applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and manufacturing origin. Ensure compatibility with the required through-hole mounting method associated with the SOT54 outline. Cross-reference the part number with the most recent product specification to confirm active production status and any potential design changes.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required for through-hole designs. The SOT54 package accommodates standard PCB drilling patterns. Verify that the 500 mW power dissipation rating meets the thermal requirements of the specific application environment. Confirm that the 47 kΩ internal resistor values align with the intended logic levels and drive currents.

Part Context

This component belongs to the PDTC144E series of NPN resistor-equipped transistors. The series includes various package options such as surface-mount types like SC-75 and SC-89. The PDTC144ES specifically utilizes the TO-92 form factor, offering a distinct alternative to the surface-mount variants within the same functional family.
