PDTC123YM,315

Overview

The PDTC123YM,315 is an NPN Resistor-Equipped Transistor (RET) from the PDTC123Y series manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 and R2 in a leadless SOT883 (SC-101) plastic package measuring 1.0 x 0.6 x 0.5 mm. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. The typical input resistor R1 is 2.2 kΩ, while the bias resistor ratio R2/R1 is typically 4.5. Total power dissipation is rated at 250 mW at 25 °C ambient temperature.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Leadless ultra-small plastic package suitable for high-density surface-mount applications
• Reduces pick and place costs compared to discrete resistor-transistor combinations

Applications

• General-purpose switching and amplification
• Circuit drivers
• Inverter and interface circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the packing method. The datasheet indicates that the -315 suffix corresponds to tape and reel packaging with a quantity of 10,000 units. Confirming this detail ensures alignment with automated assembly requirements and prevents procurement errors related to incorrect reel specifications.

Selection Notes

Select the PDTC123YM variant when a compact SOT883 footprint is required. Ensure the application operates within the 50 V collector-emitter voltage limit and 100 mA continuous current rating. Verify thermal management capabilities, as the SOT883 package has a thermal resistance of 500 K/W. Consider the PNP complement PDTA123YM if complementary logic functionality is needed.

Part Context

This component belongs to the PDTC123Y series of NPN resistor-equipped transistors. The series includes multiple package options such as SOT416, SOT346, SOT54, SOT23, and SOT323. The PDTC123YM specifically utilizes the SOT883 package, which is distinct from other series members due to its leadless ultra-small form factor designed for space-constrained PCB layouts.
