XN0438100L

Overview

The Panasonic XN04381 is a composite transistor featuring an NPN epitaxial planar type (Tr1) and a PNP epitaxial planar type (Tr2) integrated into a single SC-74 Mini6-G1 package. Designed for switching and digital circuits, it combines two elements to reduce mounting area and assembly costs. The device operates with a collector-emitter voltage of 50 V for Tr1 and -50 V for Tr2, supporting collector currents up to 100 mA and -500 mA respectively. It includes built-in base resistors (R1: 4.7 kΩ typical; R2: 4.7 kΩ typical) and achieves a total power dissipation of 300 mW at 25°C ambient temperature.

Feature Summary

• Dual-transistor integration within a compact surface-mount package
• Built-in base resistors for simplified circuit design
• Optimized for high-speed switching applications

Applications

• Digital logic interface circuits
• Switching control circuits
• General-purpose electronic equipment

Procurement Notes

Verify the current lifecycle status directly with Panasonic or authorized distributors before procurement. The datasheet indicates maintenance or discontinuation stages may apply. Confirm RoHS compliance and specific ordering suffixes match project requirements. Request the latest Product Standards document to ensure specifications remain unchanged prior to final purchasing decisions.

Selection Notes

Select this component when space constraints require combining complementary NPN and PNP transistors with fixed base resistors. Ensure the required collector current does not exceed 100 mA for the NPN section or -500 mA for the PNP section. Verify that the 300 mW total power dissipation rating accommodates the thermal environment of the target application without exceeding the junction temperature limit.

Part Context

This part belongs to Panasonic's lineup of composite transistors designed to replace discrete resistor-transistor networks. It serves as a direct functional equivalent to combinations such as UNR2213 paired with UNR2122. The integration allows designers to minimize board space while maintaining standard switching performance characteristics for general industrial and consumer electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Panasonic resources for verified cross-references or compatible alternatives.
