UP0439000L

Overview

The UP04390L is a composite transistor array from Panasonic Industry, integrating an NPN epitaxial planar transistor (Tr1) and a PNP epitaxial planar transistor (Tr2) into a single SSMini6-F1 package. Designed for switching and digital circuits, the device features built-in base resistors to reduce mounting area and assembly costs. The NPN element provides a transition frequency of 150 MHz with a collector current rating of 100 mA, while the PNP element offers an 80 MHz transition frequency with identical current handling. Both transistors share a total power dissipation limit of 125 mW at 25°C and operate within a junction temperature range up to 125°C.

Feature Summary

• Dual-element integration combining one NPN and one PNP transistor in a compact surface-mount package
• Built-in base resistors eliminate external components, reducing circuit board space and assembly complexity
• High-speed switching capability supported by transition frequencies up to 150 MHz for the NPN element

Applications

• Digital logic interface circuits
• Switching applications requiring complementary NPN/PNP pairs
• General-purpose electronic equipment and office machines

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Check the latest product lifecycle status on the official Panasonic Industry website, as this specific part number may be subject to maintenance or discontinuation plans. Ensure that the SSMini6-F1 package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select the UP04390L when a design requires both NPN and PNP switching elements with integrated biasing resistors. The NPN section is suitable for higher-frequency tasks up to 150 MHz, whereas the PNP section operates up to 80 MHz. Consider the 125 mW total power dissipation constraint when designing thermal management solutions for high-density mounting environments.

Part Context

This component belongs to the UP04 series of composite transistors manufactured by Panasonic Industry. It utilizes silicon epitaxial planar technology for both the NPN and PNP elements. The device is housed in the SSMini6-F1 leadless package, which measures approximately 1.6 mm by 1.0 mm, facilitating downsizing and high-density mounting in modern electronic equipment.

Replacement Considerations

The datasheet identifies the UNR1114 (NPN) and UNR1213 (PNP) as the basic constituent parts. Verify compatibility if substituting individual discrete transistors for this composite unit.
