UP0431100L

Overview

The Panasonic UP04311L is a composite transistor array housed in an SSMini6-F1 surface-mount package. It integrates one silicon NPN epitaxial planar transistor (Tr1) and one silicon PNP epitaxial planar transistor (Tr2), each with built-in bias resistors. The device supports a maximum collector current of 100 mA for both polarities and operates within a total power dissipation limit of 125 mW at 25°C ambient temperature. Key electrical parameters include a transition frequency of 150 MHz for the NPN element and 80 MHz for the PNP element, with a DC current gain minimum of 35 at 5 mA collector current.

Feature Summary

• Dual-element integration combining NPN and PNP transistors with internal biasing resistors into a single compact package.
• Designed to reduce printed circuit board mounting area and assembly costs by consolidating discrete components.
• Utilizes silicon epitaxial planar technology suitable for digital switching applications.

Applications

• Digital logic circuits requiring complementary switching pairs.
• General-purpose electronic equipment such as office machines and measuring instruments.
• Communications equipment signal processing stages.

Procurement Notes

Verify component status prior to ordering, as this part may be classified under maintenance or discontinued lifecycle stages. Confirm that the specific SSMini6-F1 package variant matches the design footprint requirements. Ensure compliance with RoHS Directive standards if required for the target market. Consult official manufacturer channels for current availability and latest product standards before finalizing procurement plans.

Selection Notes

Select this component when space-constrained designs require paired NPN/PNP switching elements with integrated base resistors. Verify that the 50 V collector-emitter voltage rating meets the circuit's operational limits. Consider the 125 mW total power dissipation constraint relative to the expected thermal environment. Ensure the input resistance tolerance aligns with the required biasing accuracy for the specific digital application.

Part Context

This component belongs to the UP series of composite transistors manufactured by Panasonic Industry. It serves as a direct replacement for combinations of discrete UNR2211 and UNR2111 transistors, offering a simplified layout solution. The SSMini6-F1 package provides a small form factor compared to traditional dual-transistor assemblies, facilitating denser circuit board layouts.

Replacement Considerations
