PDTC124TM,315

Overview

The PDTC124TM,315 is an NPN resistor-equipped transistor from the PDTC124T series manufactured by Nexperia. It integrates a single bias resistor (R1) of 22 kΩ with the emitter left open. The device is housed in a leadless ultra-small plastic SOT883 package (SC-101). Key electrical limits include a collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. Thermal characteristics specify a total power dissipation (Ptot) of 250 mW at 25 °C ambient temperature, with a junction-to-ambient thermal resistance of 500 K/W.

Feature Summary

• Built-in bias resistors simplify circuit design
• Reduction of component count
• Reduced pick and place costs

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT883 package dimensions align with PCB footprint requirements. Ensure thermal management strategies account for the specified 500 K/W junction-to-ambient resistance under actual operating conditions.

Selection Notes

Select this component when a compact NPN digital transistor with a 22 kΩ base resistor is required. The SOT883 package offers a small form factor suitable for space-constrained designs. Verify that the 50 V voltage rating and 100 mA current capacity meet the application's maximum stress requirements.

Part Context
