XN0121000L

Overview

The Panasonic XN01210 is a composite silicon NPN epitaxial planar transistor designed for switching and digital circuits. It integrates two emitter-coupled transistors with a built-in bias resistor into a single SC-74A (Mini5-G1) package, reducing mounting area and assembly costs by half. The device features a maximum collector-emitter voltage of 50 V, a collector current rating of 100 mA, and a total power dissipation of 300 mW at 25°C. Electrical characteristics include a forward current transfer ratio (hFE) ranging from 160 to 460 at IC = 5 mA, an input resistance of 4.7 kΩ ±30%, and a transition frequency of 150 MHz.

Feature Summary

• Integrates two emitter-coupled transistors with a built-in bias resistor into a single package
• Reduces mounting area and assembly cost by one half compared to discrete components
• Designed specifically for switching and digital circuit applications

Applications

• Switching circuits
• Digital logic circuits

Procurement Notes

Verify the exact ordering code suffix against the manufacturer's official documentation before procurement. Confirm that the component meets RoHS Directive (EU 2002/95/EC) compliance requirements for your specific manufacturing process. Check the latest product lifecycle status on the Panasonic semiconductor website to ensure availability and confirm if the part is in maintenance or discontinued phases.

Selection Notes

Select this component when space constraints require combining two transistors and a bias resistor into a single footprint. Ensure the design operates within the 50 V collector-emitter voltage limit and 300 mW total power dissipation rating. Verify that the required hFE range of 160 to 460 meets the circuit gain specifications. Consider the SC-74A package dimensions for PCB layout compatibility.

Part Context

The XN01210 belongs to Panasonic's composite transistor family, which consolidates multiple discrete elements to save board space. It is functionally related to other models like the XN01211 and XN1210, which share similar packaging but may differ in internal resistor ratios or electrical parameters. This series targets high-density digital designs where component count reduction is critical.

Replacement Considerations

Consult the datasheet for equivalent part numbers such as UNR2210 or UN2210 combinations. Verify pinout compatibility and electrical parameter overlaps before substitution. Contact Panasonic sales for confirmed cross-references.
