PDTC144WM,315

Overview

The PDTC144WM,315 is an NPN resistor-equipped transistor from the PDTC144W series manufactured by Nexperia. It integrates a single NPN bipolar junction transistor with built-in bias resistors (R1 = 47 kΩ, R2 = 22 kΩ) in a leadless ultra-small plastic package (SOT883). Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. The device features a minimum DC current gain (hFE) of 60 at IC = 5 mA. Thermal resistance from junction to ambient is 500 K/W under standard mounting conditions.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Utilizes a leadless ultra-small plastic package for reduced pick and place costs

Applications

• General purpose switching and amplification
• Inverter and interface circuits
• Circuit driver applications

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT883 package variant matches the required footprint for the target PCB layout. Ensure compatibility with reflow soldering processes as specified in the datasheet mounting conditions.

Selection Notes

Select this component when space constraints require a compact surface-mount solution for low-current switching tasks. The integrated resistor network eliminates external bias components, reducing board area. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the application circuit.
