DRA9123J0L

Overview

The DRA9123J0L is a digital transistor manufactured by Panasonic Electronic Components, housed in an SMT-3 surface-mount package with dimensions of 1.6mm x 1.6mm x 0.5mm. It integrates a PNP bipolar junction transistor with a built-in front resistor configured in a single-resistor arrangement. The device features a collector-emitter voltage (VCEO) rating of -50V and a maximum collector current (IC) of -100mA. Key electrical parameters include a DC current gain (hFE) ranging from 100 to 200 at IC = -5mA, and a base-emitter on-state voltage (VEBon) of approximately -1.1V at IB = -0.1mA.

Feature Summary

• Integrates a PNP transistor with a built-in input resistor for simplified circuit design
• Compact SMT-3 surface-mount package suitable for high-density mounting
• Designed for switching applications requiring low power consumption

Applications

• Switching circuits in portable electronic devices
• Driver stages for logic interfaces
• General-purpose signal switching in consumer electronics

Procurement Notes

Verify the specific suffix J0L against official Panasonic documentation to confirm tape-and-reel packaging specifications and quantity per reel. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to ensure authenticity and traceability, as component markings may vary slightly between manufacturing batches.

Selection Notes

Select this component when a compact PNP digital transistor with integrated biasing is required. Ensure the operating voltage does not exceed the -50V VCEO rating. Verify that the required current gain falls within the 100-200 hFE range specified for the -5mA test condition. Consider the SMT-3 package size constraints during PCB layout planning.

Part Context

This component belongs to Panasonic's series of digital transistors designed for replacing discrete resistor-transistor combinations. These devices reduce board space and assembly costs by integrating passive and active elements into a single surface-mount package. The DRA9123J0L specifically targets applications needing reliable PNP switching with minimal external components.

Replacement Considerations

Potential substitutes include the ROHM DTA123YEBTL or equivalent PNP digital transistors in SMT-3 packages. Verify pinout compatibility, voltage ratings, and current gain characteristics before substitution. Ensure the replacement part meets the same thermal and mechanical requirements for the intended application.
