XN0421500L

Overview

The XN0421500L is a composite transistor device manufactured by Panasonic Electronic Components, designed for switching and digital circuits. It integrates two NPN transistors with built-in bias resistors into a single MINI6-G1 package. The component features a collector-emitter voltage rating of 50V and a maximum collector current of 100mA per element. Electrical characteristics include a minimum DC current gain (hFE) of 160 at 5mA and a transition frequency of 150MHz. The internal connection utilizes a common emitter configuration with an input resistance of 10kΩ. Total power dissipation is rated at 300mW.

Feature Summary

• Integrates two NPN transistors with built-in bias resistors within a single package to reduce mounting area and assembly costs.

Applications

• Switching circuits
• Digital logic circuits

Procurement Notes

Verify the specific lifecycle status before procurement as this component may be discontinued or in limited supply. Confirm that the MINI6-G1 package dimensions align with the target PCB footprint. Ensure the 50V voltage rating and 100mA current limits meet the circuit requirements. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select this component when space-saving integration of dual NPN transistors with fixed bias resistors is required. The 10kΩ base resistor simplifies drive circuit design compared to discrete transistors. Verify that the 150MHz transition frequency is sufficient for the intended switching speed. Consider the 300mW total power dissipation limit when designing thermal management solutions.

Part Context

This part belongs to the XN04215 series of composite transistors from Panasonic. These devices are silicon NPN epitaxial planar types specifically engineered for general-purpose switching applications. The series offers various configurations with different resistor values, but this specific model provides a standard 10kΩ bias resistance for both elements.
