XN0A31100L

Overview

The Panasonic XN0A311 is a composite transistor featuring an NPN epitaxial planar type (Tr1) and a PNP epitaxial planar type (Tr2) integrated into a single SC-74A Mini5-G1 package. Designed for switching applications, 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

• Dual-element integration combining complementary NPN and PNP transistors in one compact package
• Built-in base resistors eliminate external components, reducing circuit board space and assembly complexity
• High-speed switching capability suitable for general electronic equipment applications

Applications

• General-purpose switching circuits in office equipment
• Signal processing in communications equipment
• Control logic in measuring instruments
• Driver stages in household appliances

Procurement Notes

Verify component lifecycle status before procurement as the product may be discontinued or subject to maintenance plans. Confirm compliance with specific environmental directives required by the target application. Consult official manufacturer channels for updated availability and lead times. Ensure design specifications align with the latest published datasheet parameters to avoid compatibility issues during production.

Selection Notes

Select this component when space constraints require dual complementary switching elements. Verify that the ±100 mA collector current rating meets load requirements. Ensure the operating voltage does not exceed the 50 V collector-emitter limit. Consider the thermal management needs given the 300 mW total power dissipation constraint in the small SC-74A package.

Part Context

This part replaces discrete UNR2211 (NPN) and UNR2111 (PNP) transistors. It consolidates two separate components into a single surface-mount device. The internal connection diagram defines pin assignments for collectors, emitters, and bases for both transistors within the five-pin configuration.

Replacement Considerations

Direct substitutes include the UNR2211 paired with UNR2111 discrete transistors. Verify pin compatibility and electrical characteristics match the original design requirements before substitution.
