UP0431NG0L

Overview

The UP0431NG is a composite transistor array from Panasonic Industry, incorporating one silicon NPN epitaxial planar transistor (Tr1) and one silicon PNP epitaxial planar transistor (Tr2) into a single SSMini6-F2 package. Designed for digital circuits, it features built-in bias resistors with a nominal value of 4.7 kΩ and a resistance ratio of approximately 0.10. The device supports a maximum collector current of 100 mA and a total power dissipation of 125 mW at 25°C. Electrical specifications include a transition frequency of 150 MHz for the NPN element and 80 MHz for the PNP element, with a collector-emitter saturation voltage of 0.25 V.

Feature Summary

• Dual-element integration combining NPN and PNP transistors with built-in bias resistors in a compact surface-mount package.
• Designed to reduce mounting area and assembly costs by consolidating discrete components into a single unit.
• Optimized for digital circuit applications with specified high-level and low-level output voltage characteristics.

Applications

• Digital logic interface circuits
• General-purpose switching applications in office equipment
• Communications equipment signal processing
• Household appliance control boards

Procurement Notes

Verify component authenticity through authorized Panasonic Industry distributors or certified suppliers. Confirm the specific ordering suffix matches the required packaging format, as variations exist between tape-and-reel and cut-tape options. Ensure compliance with RoHS directives applicable to your region. Check the manufacturer's official lifecycle status page for current availability and discontinuation notices before finalizing procurement plans.

Selection Notes

Select this component when space constraints require a combined NPN/PNP pair with integrated base resistors. Verify that the 4.7 kΩ internal resistance values align with the target logic family drive requirements. Ensure the 50V collector-emitter voltage rating exceeds the maximum operating voltage of the application circuit. Consider the SSMini6-F2 footprint dimensions during PCB layout design to ensure adequate clearance.

Part Context

The UP0431NG belongs to the UP0431 series of composite transistors manufactured by Panasonic Industry. It utilizes the SSMini6-F2 surface-mount package, which measures 1.6mm x 1.2mm. This series is engineered to replace multiple discrete components, simplifying bill-of-materials and reducing assembly complexity for standard electronic equipment such as measuring instruments and consumer appliances.
