PDTC124EU-QX

Overview

The PDTC124EU-Q is an NPN Resistor-Equipped Transistor (RET) housed in a compact SOT323 (SC-70) surface-mounted package. It integrates bias resistors R1 and R2, both nominally 22 kΩ, to simplify circuit design. The device supports a collector-emitter voltage of 50 V and an output current of 100 mA. Qualified under AEC-Q101 standards, it operates within a temperature range of -65 °C to +150 °C. Key electrical characteristics include a DC current gain of at least 60 at 5 mA and a transition frequency of 230 MHz.

Feature Summary

• Integrated bias resistors reduce component count and assembly costs
• AEC-Q101 qualified for automotive reliability requirements
• Compact SC-70 package suitable for space-constrained designs

Applications

• Digital logic applications in automotive systems
• Industrial digital control circuits
• Switching loads and controlling IC inputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and tape-and-reel specifications. Confirm that the requested revision level matches the current product data sheet version. Ensure compliance with RoHS directives and REACH regulations as stated in the legal information section before finalizing procurement orders.

Selection Notes

Select this component when a small form factor is required alongside integrated base biasing. The 22 kΩ input resistor value is suitable for standard logic interface applications. Consider the thermal resistance of 625 K/W in free air when designing for high ambient temperatures or limited PCB copper area.

Part Context

This part belongs to Nexperia's family of NPN resistor-equipped transistors designed for digital switching. It serves as a direct replacement for discrete resistor-transistor networks, offering a simplified alternative to components like the BC847 series in digital logic environments while maintaining automotive-grade qualification standards.

Replacement Considerations

The PDTA124EU is the PNP complement within the same series. Verify pinout compatibility if substituting with other RETs from different manufacturers, as internal resistor configurations may vary despite identical external markings.
