DRA3144E0L

Overview

The DRA3144E0L is a PNP digital transistor manufactured by Panasonic Electronic Components, designed for compact surface-mount applications. It integrates a single PNP transistor with a built-in bias resistor of 47 kOhms within an SSSMini3-F2-B package measuring 1.2x1.2mm. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. It operates at temperatures up to +150 C and is supplied in reel, cut tape, or MouseReel formats.

Feature Summary

• Integrates a PNP transistor with a built-in 47 kOhm bias resistor to simplify circuit design.
• Utilizes a compact 1.2x1.2mm SSSMini3-F2-B surface-mount package for space-constrained layouts.
• Supports high-temperature operation with a maximum junction temperature of +150 C.

Applications

• Switching circuits in portable electronic devices requiring minimal board space.
• Interface drivers for logic level translation in embedded systems.
• General-purpose switching applications in consumer electronics.

Procurement Notes

Verify the specific suffix E0L against official Panasonic documentation to confirm exact packaging and tape-and-reel specifications. Confirm availability status as distribution channels may list this component as end-of-life or limited supply. Ensure compliance with RoHS directives by checking the manufacturer's latest certification documents before procurement.

Selection Notes

Select the DRA3144E0L when a small form factor is required alongside integrated biasing functionality. The 47 kOhm internal resistor value should match the driving source impedance requirements. Consider the -50 V rating and -100 mA current limit to ensure adequate headroom for the target application's electrical loads.

Part Context

This component belongs to Panasonic’s series of digital transistors, which combine bipolar junction transistors with on-chip resistors. The DRA3144E0L specifically utilizes the SSSMini3-F2-B package, part of Panasonic's miniaturized transistor lineup aimed at reducing footprint in modern PCB designs compared to traditional discrete resistor-transistor combinations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference data. Cross-reference with other PNP digital transistors in the SSSMini3-F2-B package only after verifying pinout compatibility and electrical parameter equivalence through official datasheets.
