XN0111M00L

Overview

The XN0111M is a silicon PNP epitaxial planar composite transistor designed for switching and digital circuits. It integrates two emitter-coupled transistors with a built-in resistor into a single SC-74A package, reducing mounting area and assembly costs by half compared to discrete components. The device features a collector-emitter breakdown voltage of -50 V, a maximum collector current of -100 mA, and a total power dissipation of 300 mW at 25°C. Key electrical characteristics include a forward current transfer ratio (hFE) of 80 at -5 mA, an input resistance (R1) of 2.2 kΩ, and a transition frequency (fT) of 80 MHz.

Feature Summary

• Integrates two emitter-coupled transistors with a built-in bias resistor within a single package
• Reduces required mounting area and assembly costs by approximately 50 percent
• Designed specifically for high-speed switching and digital logic applications

Applications

• General-purpose switching circuits in office equipment
• Digital signal processing interfaces in communications equipment
• Control logic within measuring instruments
• Standard household appliance circuitry

Procurement Notes

Verify the specific lifecycle status directly with Panasonic Industry before procurement, as this component may be subject to maintenance or discontinuation plans. Confirm that the SC-74A package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Request the latest product standards document to verify current specifications prior to final design approval.

Selection Notes

Select this component when space constraints require combining multiple transistor functions into one footprint. The integrated resistor simplifies biasing networks, reducing external component count. Verify that the -50 V collector-emitter voltage rating meets the system's maximum operating voltage. Consider the 300 mW total power dissipation limit relative to the ambient temperature conditions of the final enclosure.

Part Context

This part belongs to the XN series of composite transistors manufactured by Panasonic Electronic Components. It serves as a direct functional equivalent to two UNR211M discrete units combined into a single SMD package. The marking symbol on the component body is EK. It utilizes the EIAJ SC-74A Mini5-G1 package standard for surface mount technology.

Replacement Considerations

Direct substitutes include the UNR211M used in pairs, though this requires double the board space. Verify pinout compatibility when replacing with other composite transistor families. Check if alternative manufacturers offer identical hFE ratios and saturation voltages for critical switching performance.
