XN0121200L

Overview

The XN01212 is a composite NPN transistor device manufactured by Panasonic Electronic Components, designed for switching and digital circuits. It integrates two emitter-coupled transistors with built-in bias resistors into a single SC-74A (Mini5-G1) package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 60 at 5 mA, a transition frequency of 150 MHz, and a total power dissipation rating of 300 mW. The internal configuration features a resistance ratio between the two elements ranging from 0.8 to 1.2.

Feature Summary

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

Applications

• Switching circuits
• Digital logic circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check current lifecycle stage via official Panasonic resources before procurement. Ensure storage conditions meet specified limits to prevent degradation prior to use.

Selection Notes

Select this component when space constraints require integrating dual transistor functions with fixed bias ratios. Verify that the 50 V voltage rating and 100 mA current capacity align with circuit requirements. Consider the 150 MHz transition frequency for high-speed switching needs.

Part Context

This device belongs to the XN series of composite transistors from Panasonic. It serves as a replacement for configurations previously requiring two separate UNR2212/UN2212 units. The Mini5-G1 package provides a compact footprint suitable for dense PCB layouts.

Replacement Considerations

The datasheet identifies UNR2212 (UN2212) × 2 as the conventional equivalent configuration. Verify pinout compatibility and electrical parameter alignment when substituting discrete components.
