UP0431500L

Overview

The UP04315 is a composite transistor device manufactured by Panasonic Electronic Components, designed for switching and digital circuits. It integrates two elements into one package: an NPN epitaxial planar transistor (Tr1) and a PNP epitaxial planar transistor (Tr2), both featuring built-in bias resistors. The device operates with a maximum collector-emitter voltage of 50 V and a total power dissipation of 125 mW. Tr1 provides a typical forward current transfer ratio (hFE) of 460 at IC = 5 mA, while Tr2 offers a typical hFE of 460 under similar conditions. The input resistance is nominally 10 kΩ with a tolerance of ±30%. Transition frequencies are specified at 150 MHz for Tr1 and 80 MHz for Tr2.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistors in a single SSMini6-F1 package
• Reduces mounting area and assembly costs by consolidating two discrete elements
• Optimized for high-speed switching and digital logic applications

Applications

• Switching circuits
• Digital logic interfaces
• General electronic equipment

Procurement Notes

Verify the current lifecycle status directly through official Panasonic channels before procurement. The datasheet indicates potential maintenance or discontinuation stages that may affect long-term availability. Confirm RoHS compliance requirements and ensure the specific package variant matches design constraints. Request the latest Product Standards to validate specifications prior to finalizing orders.

Selection Notes

Select this component when space-saving integration of complementary switching pairs is required. Ensure the 10 kΩ internal resistor value aligns with the target logic levels and drive currents. Verify that the 125 mW total power dissipation rating accommodates the thermal environment. Consider the transition frequency limits if operating near high-speed signal boundaries.

Part Context

This part belongs to the UP series of composite transistors from Panasonic. It serves as a compact alternative to using separate NPN and PNP devices with external biasing networks. The SSMini6-F1 package allows for surface-mount implementation in dense circuit layouts.

Replacement Considerations

The datasheet identifies UNR2215 and UNR2115 as basic constituent parts. Verify pinout compatibility and electrical characteristics against these individual components if substituting with discrete equivalents.
