DRA9124E0L

Overview

The DRA9124E0L is a pre-biased PNP transistor manufactured by Panasonic Electronic Components. It integrates two internal base resistors: R1 at 22 kΩ and R2 at 22 kΩ, simplifying circuit design by eliminating external biasing components. The device features a maximum collector current (IC) of 100 mA and a collector-emitter breakdown voltage (VCEO) of 50 V. Key electrical characteristics include a DC current gain (hFE) of at least 60 at IC = 5 mA and VCE = 10 V, with a maximum collector-emitter saturation voltage (VCEsat) of 250 mV at IC = 10 mA and IB = 500 µA. The unit has a maximum power dissipation of 125 mW and is housed in an SSmini3-F3-B package.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific ordering suffix matches the required package variant. Review the manufacturer datasheet for handling precautions and soldering profiles to ensure assembly integrity. Validate that the discontinued status does not impact long-term supply requirements.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required. Ensure the 100 mA current rating and 50 V voltage rating exceed the application's peak operational demands. Verify that the 125 mW power dissipation capability accommodates the thermal environment without exceeding junction temperature limits.

Part Context

This part belongs to Panasonic's lineup of pre-biased transistors designed to reduce board space and component count. These devices combine standard bipolar transistors with built-in resistors to streamline digital logic interfacing and switching control tasks in consumer and industrial electronics.

Replacement Considerations

Consult official cross-reference documentation for verified substitutes. Ensure any replacement maintains identical pinout configuration, electrical ratings, and package dimensions to guarantee mechanical and functional compatibility.
