XP0431N00L

Overview

The Panasonic XP0431N is a composite transistor featuring an NPN epitaxial planar type (Tr1) and a PNP epitaxial planar type (Tr2) integrated into a single SMini6-G1 package. Designed for digital circuits, it incorporates built-in bias resistors with a nominal value of 4.7 kΩ and a resistance ratio of 0.1. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA per element. Total power dissipation is rated at 150 mW at 25°C ambient temperature. Transition frequencies are specified at 150 MHz for the NPN section and 80 MHz for the PNP section.

Feature Summary

• Dual-element integration combining NPN and PNP transistors within a single compact package to reduce mounting area.
• Built-in bias resistors eliminate external resistor requirements, simplifying circuit design and assembly.
• Epitaxial planar construction ensures stable electrical characteristics suitable for digital switching applications.

Applications

• Digital logic interface circuits
• General-purpose switching applications in electronic equipment
• Driver stages for low-power digital loads

Procurement Notes

Verify component authenticity through authorized Panasonic distributors or official channels. Confirm the specific revision status and lifecycle stage via Panasonic's semiconductor website prior to procurement. Ensure compliance with RoHS directives as stated in the datasheet. Validate that the SMini6-G1 package dimensions match the target PCB footprint during final design review.

Selection Notes

Select this component when space constraints require dual complementary switching elements in a minimal footprint. Verify that the 100 mA current rating and 150 mW power dissipation meet the thermal requirements of the application. Consider the 4.7 kΩ internal resistance for base drive calculations. Ensure operating temperatures remain within the -55°C to +150°C storage range and appropriate junction limits during operation.

Part Context

The XP0431N belongs to Panasonic's series of composite transistors designed to replace discrete resistor-transistor networks. It serves as a direct functional replacement for combinations like UNR221N and UNR211N. This integration strategy reduces board space and assembly costs while maintaining reliable performance in standard digital electronics.

Replacement Considerations

Publicly confirmed substitute part numbers include UNR221N and UNR211N. Verify pin compatibility and electrical parameters against the original design requirements before substitution.
