UP0121M00L

Overview

The UP0121M00L is a composite transistor manufactured by Panasonic Electronic Components, featuring two NPN silicon epitaxial planar transistors integrated into a single SSMini5-F2 package. It incorporates built-in bias resistors (R1: 2.2 kΩ, R2: 47 kΩ) to reduce mounting area and assembly costs. The device supports a collector current of 100 mA and a collector-emitter voltage of 50 V with a total power dissipation of 125 mW at 25°C ambient temperature. Designed for switching and digital circuits, it offers a transition frequency of 150 MHz and complies with the RoHS Directive.

Feature Summary

• Two emitter-coupled transistors with built-in resistors incorporated into one package
• SSMini type package designed for reduction of mounting area and assembly cost

Applications

• Switching circuits
• Digital circuits

Procurement Notes

Verify component authenticity through authorized distributors or official Panasonic channels. Confirm compliance with specific environmental directives required by your manufacturing process. Review the latest product standards directly from the manufacturer before finalizing procurement decisions to ensure specifications remain current.

Selection Notes

Select this component when space constraints require integrating dual transistors with fixed bias networks. Ensure the design operates within the 125 mW total power dissipation limit at the expected ambient temperature. Verify that the 50 V collector-emitter voltage rating exceeds the maximum circuit operating voltage under all transient conditions.

Part Context

This part belongs to the UP0121 series of composite transistors produced by Panasonic Electronic Components. These devices are engineered specifically for applications requiring compact solutions for logic interfacing or signal switching where discrete resistor placement would otherwise consume excessive board real estate.

Replacement Considerations

The datasheet identifies UNR221M as the basic part number equivalent to two individual elements. No other specific substitute part numbers are documented in the provided source material.
