Overview

The XN01112 is a composite transistor device manufactured by Panasonic Electronic Components, designed for switching and digital circuits. It integrates two PNP epitaxial planar transistors with built-in bias resistors into a single SC-74A (Mini5-G1) package. The component features a collector-emitter voltage rating of -50 V and a maximum collector current of -100 mA per element. Total power dissipation is rated at 300 mW. Key electrical characteristics include a forward current transfer ratio (hFE) of 60 at -5 mA and an input resistance of 22 kΩ. The transition frequency is specified at 80 MHz.

Feature Summary

• Integrates two emitter-coupled transistors with built-in resistors within a single package to reduce mounting area and assembly costs.

Applications

• Switching circuits
• Digital logic circuits

Procurement Notes

Verify the specific lifecycle status of the XN01112 directly with Panasonic or authorized distributors before procurement. The datasheet indicates maintenance or discontinuation plans may apply. Confirm that the SC-74A package availability aligns with long-term supply requirements. Ensure compliance with RoHS directives if required for the target application environment.

Selection Notes

Select this component when space-saving integration of dual PNP transistors with fixed bias ratios is required. The internal resistor ratio allows for simplified circuit design compared to discrete components. Verify that the -50 V voltage rating and -100 mA current limits meet the specific load requirements of the switching application.

Part Context

This part belongs to the XN series of composite transistors from Panasonic. These devices are engineered to replace multiple discrete components, offering a compact solution for digital logic applications. The XN01112 specifically utilizes PNP technology, contrasting with NPN variants in the same family.

Replacement Considerations

The datasheet identifies UNR2112 (UN2112) as the conventional equivalent part number. Designers should verify pinout compatibility and electrical parameter tolerances when substituting with other dual PNP composite transistors from different manufacturers.
