DRA3143E0L

Overview

The DRA3143E0L is a single PNP digital transistor manufactured by Panasonic Industry. It integrates a built-in input resistor with a typical value of 2.2 kOhms, simplifying circuit design by reducing component count and board space. The device is housed in an SSSMini3-F2-B surface-mount package measuring 1.2x1.2mm. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. It supports a maximum operating temperature of +150 C and is available in reel, cut tape, and MouseReel packaging formats.

Feature Summary

• Integrates a built-in input resistor to simplify biasing circuits and reduce footprint.
• Utilizes the compact SSSMini3-F2-B surface-mount package for high-density mounting.
• Supports high-temperature operation up to +150 C for robust performance.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for low-current loads in industrial control systems.
• Logic interface stages between microcontrollers and peripheral devices.

Procurement Notes

Verify availability status as the component may be discontinued or subject to limited supply. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure ordering suffixes match specific packaging requirements such as reel or cut tape quantities. Cross-reference datasheets for any recent product change notifications affecting specifications.

Selection Notes

Select this component when a PNP digital transistor with a 2.2 kOhm input resistance is required. Compare against alternatives like DRC3143E0L if NPN polarity is needed instead. Consider the SSSMini3-F2-B package dimensions for PCB layout constraints. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the Panasonic Digital Transistor series, which combines bipolar junction transistors with internal resistors. These components are designed to replace discrete resistor-transistor combinations, offering improved reliability and reduced assembly costs. The DRA3143E0L specifically addresses applications requiring PNP logic switching with defined input impedance characteristics.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the available source material. Engineers should consult official Panasonic Industry documentation or authorized distributors for validated cross-references. Verify pinout compatibility and electrical parameter equivalence before substituting.
