XN0421F00L

Overview

The Panasonic XN0421F is a composite transistor featuring two integrated NPN elements within an SC-74 Mini6-G1 package. It incorporates built-in resistors to reduce mounting area and assembly costs. Key electrical parameters include a collector-base voltage (V_CBO) of 50 V, collector-emitter voltage (V_CEO) of 50 V, and a maximum collector current (I_C) of 100 mA. The device has a total power dissipation rating of 300 mW at 25°C and operates within a junction temperature range up to 150°C. Input resistance is nominally 4.7 kΩ with a ±30% tolerance.

Feature Summary

• Dual NPN transistors integrated into a single surface-mount package
• Built-in base resistors for simplified circuit design
• Reduced footprint and assembly complexity compared to discrete components

Applications

• General electronic equipment
• Office equipment
• Communications equipment
• Measuring instruments
• Household appliances

Procurement Notes

Verify the specific lifecycle status through official channels before procurement, as the datasheet indicates maintenance or discontinuation phases may apply. Confirm that the SC-74 Mini6-G1 package dimensions align with your PCB layout requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards.

Selection Notes

Select this component when space constraints require dual switching functions in a minimal footprint. Verify that the 100 mA collector current and 50 V voltage ratings meet the load requirements. Consider the fixed input resistance values; ensure they are compatible with the driving logic levels without requiring additional external biasing components.

Part Context

This part belongs to the XN series of composite transistors from Panasonic Electronic Components. These devices are designed specifically for digital switching applications where multiple transistors with associated resistors are needed. The XN0421F serves as a direct replacement for configurations previously using separate discrete transistors and resistors.

Replacement Considerations

The datasheet identifies UNR221F as the conventional equivalent part number. When substituting, verify pinout compatibility between the SC-74 Mini6-G1 package and alternative packages. Ensure the replacement device meets the same 50 V and 100 mA specifications.
