PDTC124XQCZ

Overview

The PDTC124XQCZ is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a DFN1412D-3 (SOT8009) leadless surface-mount package. It features built-in bias resistors with nominal values of R1 = 22 kΩ and R2 = 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at IC = 5 mA and VCE = 5 V, and a typical transition frequency (fT) of 230 MHz. The package height is 0.5 mm, facilitating compact circuit designs.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• Ultra-small leadless DFN1412D-3 package with side-wettable flanks for improved solder joint inspection
• Low profile construction suitable for space-constrained applications

Applications

• Digital logic switching applications
• Controlling inputs on integrated circuits
• Cost-effective alternative to discrete transistor-resistor networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm packaging format and reel specifications. Ensure that the DFN1412D-3 footprint matches your PCB layout guidelines, particularly regarding stencil thickness and reflow soldering profiles. Confirm RoHS compliance status through official datasheets before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN switch with integrated base biasing is required. The 22 kΩ input resistor value determines the drive current requirements compared to other series variants like PDTC143XQC or PDTC123JQC. Verify that the 50 V breakdown voltage meets the system's operational limits and that the thermal resistance characteristics are sufficient for the intended power dissipation levels.

Part Context

This part belongs to the Nexperia PDTC143X/123J/143Z/114Y/124XQC series of 50 V, 100 mA NPN resistor-equipped transistors. The series offers various resistor combinations within the same SOT8009 package footprint, allowing designers to standardize assembly processes while adjusting biasing parameters for different digital logic interfaces.

Replacement Considerations

Direct functional substitutes within the same package include PDTC143XQC, PDTC123JQC, PDTC143ZQC, and PDTC114YQC. These parts share identical pinouts and physical dimensions but differ in internal resistor values. Ensure the replacement variant's bias ratio aligns with the original circuit design requirements.
