Overview
The PDTC124XM,315 is an NPN Resistor-Equipped Transistor (RET) from the PDTC124X series, manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 and R2 in a compact SOT883 (SC-101) leadless package. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. The typical input bias resistor R1 is 22 kΩ, with a standard R2/R1 ratio of 2.1. Key electrical characteristics include a DC current gain (hFE) minimum of 80 at IC = 5 mA, a collector-emitter saturation voltage (VCEsat) maximum of 150 mV at IC = 10 mA, and a total power dissipation (Ptot) of 250 mW.
Feature Summary
- Integrates NPN transistor with built-in bias resistors to reduce component count and simplify circuit design.
- Offers general-purpose switching and amplification capabilities suitable for circuit drivers and interface applications.
- Provides reduced pick and place costs due to the compact surface-mount package configuration.
Applications
- General-purpose switching and amplification
- Circuit drivers
- Inverter and interface circuits
Procurement Notes
Verify the specific ordering suffix '315' against official Nexperia documentation to confirm the packing method, as this code indicates the tape and reel format for the SOT883 package. Ensure that the procurement source provides valid traceability data consistent with the manufacturer's quality standards. Cross-reference the part number with the most recent product data sheet to confirm availability and any potential obsolescence notices before finalizing orders.
Selection Notes
Select the PDTC124XM variant when a leadless ultra-small plastic package (SOT883) is required for space-constrained designs. This model is appropriate for applications needing an NPN RET with a 22 kΩ input resistor and a 50 V collector-emitter rating. Consider the thermal resistance of 500 K/W for heat dissipation planning. Verify compatibility with reflow soldering processes, as this is the only recommended soldering method for this component.
Part Context
The PDTC124XM belongs to the broader PDTC124X family of NPN resistor-equipped transistors. While sharing identical electrical specifications with other series members like the PDTC124XT or PDTC124XU, it is distinguished by its unique SOT883 (SC-101) package. This family allows designers to choose between various form factors, such as SOT23 or SOT323, based on board layout requirements without altering the underlying circuit functionality.
Replacement Considerations
Direct replacements within the same electrical specification include PDTC124XT (SOT23), PDTC124XU (SOT323), and PDTC124XE (SOT416). These alternatives share the same NPN RET characteristics but differ in physical package dimensions and pinout orientation. Verify footprint compatibility and thermal performance differences when substituting these packages.
