PDTA124EU,135

Overview

The PDTA124EU,135 is a PNP Resistor-Equipped Transistor (RET) manufactured by Nexperia in the SOT-323 (SC-70) surface-mounted package. It integrates a single PNP transistor with built-in bias resistors R1 and R2, both nominally 22 kΩ. The device supports an output current of -100 mA and withstands a collector-emitter voltage of -50 V. Key electrical characteristics include a DC current gain (hFE) of at least 60 at -5 mA, a transition frequency of 180 MHz, and a total power dissipation of 200 mW at 25 °C ambient temperature. It operates within a junction temperature range up to 150 °C.

Feature Summary

• Integrates a PNP transistor with two internal bias resistors to reduce component count and simplify circuit design.
• Qualified for automotive applications under the AEC-Q101 standard.
• Designed as a cost-saving alternative to discrete BC847/BC857 series transistors in digital switching applications.

Applications

• Control of IC inputs
• Switching loads
• Digital applications in automotive segments
• Digital applications in industrial segments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the packaging configuration. The suffix '135' indicates a tape and reel packing method with a quantity of 3000 units per reel for the SOT-323 package. Confirm that the marking code corresponds to the manufacturing site requirements for your assembly line.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the load current remains within the -100 mA continuous limit. Verify thermal management capabilities if operating near the maximum junction temperature or power dissipation limits.

Part Context

This part belongs to the PDTA124E series of PNP resistor-equipped transistors from Nexperia. The series includes variants in different packages such as SOT23, SOT416, and SOT883. The PDTA124EU specifically utilizes the SOT-323 footprint, offering a very small form factor suitable for space-constrained designs while maintaining the same electrical performance as other series members.

Replacement Considerations

PDTC124EU is the NPN complement within the same family. For direct replacement in existing designs, verify pin compatibility and ensure the polarity change aligns with the circuit topology. Other series members like PDTA124ET (SOT-23) share electrical specs but differ in physical dimensions.
