DRC3123E0L

Overview

The DRC3123E0L is a silicon PNP epitaxial planar transistor with a built-in bias resistor, manufactured by Panasonic Electronic Components. Designed for digital circuits, it utilizes the SSSMini3 package (SC-105AA), measuring 1.2x1.2mm. Key electrical parameters include a maximum collector-emitter voltage of 50V and a maximum collector current of 0.1A. The device features a minimum DC current gain (hFE) of 30 and a built-in bias resistor ratio of 4.55. It operates as a single component with low collector-emitter saturation voltage.

Feature Summary

• Integrated bias resistor simplifies circuit design by reducing external component count.
• Low collector-emitter saturation voltage enhances switching efficiency in digital applications.
• Halogen-free construction complies with EU RoHS directives and UL-94 V-0 standards.

Applications

• Digital logic interface circuits
• Switching applications requiring compact form factors
• General-purpose transistor circuits in consumer electronics

Procurement Notes

Verify the manufacturer part number against official Panasonic documentation to ensure authenticity. Confirm compliance requirements such as halogen-free status and RoHS adherence prior to procurement. Check for specific ordering suffixes that may indicate packaging variations or material changes. Ensure the supplier provides valid traceability documents matching the specified SC-105AA package type.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. The SSSMini3 package suits space-constrained designs. Verify that the 50V collector-emitter voltage and 0.1A current limits meet the target application's electrical demands. Consider the built-in resistor ratio of 4.55 for base drive calculations instead of discrete resistor selection.

Part Context

The DRC3123E0L belongs to Panasonic's series of transistors with built-in resistors, specifically designed for digital circuits. It shares functional similarities with other models in the DRA/DRC series but differs in package size and specific electrical characteristics. The SSSMini3 package distinguishes it from larger standard transistor packages, offering a smaller footprint for modern surface-mount applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with Panasonic's internal substitution guides or consult technical support for verified equivalents. Do not assume compatibility with generic PNP transistors without verifying pinout and electrical parameter alignment.
