PDTC124ET-QR

Overview

The PDTC124ET-QR is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia USA Inc. It integrates a transistor with built-in bias resistors R1 and R2, both nominally 22 kΩ, into a single SOT-23 (TO-236AB) surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous output current of 100 mA. It operates within an ambient temperature range of -65 °C to +150 °C and features a total power dissipation of 250 mW at 25 °C. Qualified under AEC-Q101 standards, it includes a transition frequency of 230 MHz and a DC current gain minimum of 60.

Feature Summary

• Integrates dual bias resistors to reduce component count and simplify circuit design
• Qualified according to AEC-Q101 for automotive applications
• Provides cost-saving alternative to discrete BJT configurations in digital logic

Applications

• Digital applications in automotive and industrial segments
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific suffix 'QR' against the manufacturer's official documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering code matches the exact SOT-23 variant required for your PCB footprint. Cross-reference the marking code '%17' with manufacturing site codes to validate authenticity and traceability during incoming inspection.

Selection Notes

Select this component when a compact NPN switching solution with integrated base biasing is required. The 22 kΩ resistor values are suitable for standard logic level driving. Consider the PNP complement PDTA124ET-Q if a complementary polarity is needed. Verify that the 50 V breakdown voltage meets the system's peak transient requirements before finalizing the design.

Part Context

This part belongs to the PDTC124ET family of resistor-equipped transistors from Nexperia. It serves as the NPN counterpart to the PDTA124ET series. The product line is designed to replace multiple discrete components, offering space savings on printed circuit boards while maintaining reliable performance in high-volume manufacturing environments.

Replacement Considerations

The PNP equivalent is PDTA124ET-Q. For non-automotive grades, the standard PDTC124ET may be considered if AEC-Q101 qualification is not required.
