DRA5144V0L

Overview

The DRA5144V0L is a pre-biased PNP digital transistor manufactured by Panasonic Electronic Components. It integrates a single bipolar junction transistor with built-in bias resistors in a Mini3-G3-B surface-mount package. Key electrical specifications include a collector-emitter maximum voltage (VCEO) of -50 V and a continuous collector current rating of -100 mA. The device features a typical input resistance of 47 kOhms and supports a maximum operating temperature of +150°C. It is designed for compact circuit applications requiring integrated biasing solutions.

Feature Summary

• Integrates a PNP bipolar transistor with built-in bias resistors to simplify circuit design
• Utilizes a Mini3-G3-B surface-mount package for space-efficient PCB layout
• Supports high-temperature operation up to +150°C for robust performance

Applications

• General-purpose switching circuits
• Logic interface buffering
• Driver stages for low-power loads

Procurement Notes

Verify component authenticity through authorized Panasonic distributors or certified suppliers. Request original manufacturer documentation, including datasheets and product change notifications, to confirm compliance with RoHS standards and lead-free requirements. Ensure storage conditions meet specified humidity and temperature limits to prevent degradation prior to assembly.

Selection Notes

Select the DRA5144V0L when a compact PNP solution with integrated biasing is required. Confirm that the -50 V voltage rating and -100 mA current capacity align with load requirements. Evaluate the 47 kOhm input resistance against drive source capabilities. Consider the Mini3-G3-B footprint compatibility during PCB layout planning.

Part Context

This component belongs to Panasonic's DRA series of pre-biased digital transistors. These devices combine NPN or PNP transistors with internal resistors to reduce external component count. The DRA5144V0L specifically addresses applications needing reliable PNP switching in minimal space, offering a standardized alternative to discrete resistor-transistor combinations.

Replacement Considerations

Cross-reference with other Panasonic DRA series PNP devices sharing the Mini3-G3-B package. Verify equivalent electrical parameters, particularly VCEO, Ic, and input resistance values, before substitution. Ensure thermal characteristics and pinout configurations match the original design requirements.
