UP0421500L

Overview

The Panasonic UP0421500L is a composite transistor from the UP0421x series, featuring two silicon NPN epitaxial planar elements integrated into a single SSMini6-F1 package. Designed for switching and digital circuits, it incorporates a built-in base resistor (R1) of 10 kΩ with no second resistor (R2). The device supports a collector current of 100 mA and a total power dissipation of 125 mW at 25°C. It operates within an ambient temperature range of -55°C to +125°C and complies with the RoHS Directive.

Feature Summary

• Integrates two NPN transistors into one compact package to reduce mounting area and assembly costs.

Applications

• Switching circuits
• Digital logic circuits

Procurement Notes

Verify component status before procurement as the UP0421x series may be subject to maintenance or discontinuation phases. Consult official Panasonic semiconductor lifecycle documentation for current availability and obsolescence warnings. Ensure design compliance with absolute maximum ratings during transient states such as power-on and mode-switching to prevent device failure.

Selection Notes

Select the UP0421500L when a dual NPN configuration with a single 10 kΩ base resistor is required. Verify that the 125 mW total power dissipation rating accommodates thermal constraints in the target application. Confirm compatibility with standard surface mount processes and ensure the SSMini6-F1 footprint fits the PCB layout requirements.

Part Context

The UP0421500L belongs to the UP0421x series of composite transistors manufactured by Panasonic Electronic Components. This series consolidates multiple discrete transistor functions into a single surface-mount package to optimize board space. The specific UP04215 variant provides two NPN elements with one internal base resistor, distinguishing it from other series members that offer different resistance values or dual-resistor configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should consult Panasonic's official replacement guide or contact technical support for verified cross-references due to potential lifecycle changes.
