XN0A31200L

Overview

The Panasonic XN0A312 is a composite transistor featuring an NPN epitaxial planar transistor (Tr1) and a PNP epitaxial planar transistor (Tr2) integrated into a single SC-74A Mini5-G1 package. Designed for switching and digital circuits, it incorporates built-in base resistors to reduce mounting area and assembly costs. The device supports a maximum collector current of 100 mA per element with a total power dissipation of 300 mW. It operates within a junction temperature range up to 150°C and complies with the RoHS Directive.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in resistors in one package
• Reduces printed circuit board mounting area and assembly costs by half
• Suitable for general-purpose switching and digital logic applications

Applications

• General-purpose switching circuits
• Digital logic interface applications
• Standard office equipment and communications equipment

Procurement Notes

Verify component lifecycle status directly with Panasonic or authorized distributors before procurement. The datasheet indicates this product falls under maintenance or discontinued categories. Confirm availability of the latest Product Standards to ensure specifications remain unchanged prior to final design implementation.

Selection Notes

Select this component when space constraints require combining complementary switching elements. Ensure the design accounts for the 300 mW total power dissipation limit shared between both transistors. Verify that the 100 mA collector current rating meets the load requirements for both NPN and PNP sections simultaneously.

Part Context

This part replaces discrete UNR2212 (NPN) and UNR2112 (PNP) transistors. It consolidates two separate components into a single EIAJ SC-74A Mini5-G1 package. The marking symbol on the device is 4P. It serves as a direct footprint-compatible alternative for designs previously utilizing the paired discrete units.
