DRA2543E0L

Overview

The Panasonic DRA2543E0L is a PNP digital transistor featuring a built-in bias resistor, housed in the Mini3 G3 B surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and supports a continuous DC collector current of up to 500 mA. The device dissipates a maximum power of 200 mW and functions reliably within an operating temperature range extending to +150 °C. Key electrical characteristics include a typical input resistance of 4.7 kΩ and a typical resistance ratio of 1. Designed for compact digital circuits, it integrates a single NPN-type configuration structure adapted for PNP operation within a 2.9 x 1.5 x 1.1 mm footprint.

Feature Summary

• Integrates a built-in bias resistor to simplify circuit design and reduce component count.
• Engineered for low collector-emitter saturation voltage to enhance switching efficiency.
• Constructed using silicon epitaxial planar technology for stable digital performance.
• Compliant with halogen-free standards and RoHS directives for environmental safety.

Applications

• Digital logic interface circuits requiring level shifting or buffering.
• Switching applications in portable electronic devices with space constraints.
• General-purpose transistor arrays in consumer electronics control boards.

Procurement Notes

Verify the specific ordering code suffix against official Panasonic documentation to ensure correct variant selection. Confirm that the requested units match the Mini3 G3 B package dimensions and pinout configuration. Check for RoHS compliance markings on packaging to meet regulatory requirements. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet prior to assembly.

Selection Notes

Select this component when a compact PNP digital switch with integrated biasing is required. Compare the 500 mA current rating and 50 V voltage limit against circuit demands. Evaluate the 4.7 kΩ input resistance for compatibility with driving logic levels. Consider the +150 °C maximum junction temperature for high-thermal environments compared to standard alternatives.

Part Context

This part belongs to Panasonic's series of resistors-biased transistors designed for digital applications. It utilizes the SSSMini3 package format, which is optimized for high-density PCB layouts. The DRA2543E0L serves as a discrete solution for replacing multiple discrete components, offering a standardized alternative within the broader family of Panasonic semiconductor devices.

Replacement Considerations

Cross-reference with Panasonic models such as DRC2543E0L for NPN equivalents or other DRA-series variants. Verify pin compatibility and electrical parameters before substitution. Ensure any replacement maintains the same Mini3 G3 B footprint and thermal characteristics.
