XP0121100L

Overview

The XP0121100L is a composite transistor device manufactured by Panasonic, featuring two NPN elements integrated into a single SMini5-G1 package. It operates with a maximum collector-emitter voltage of 50 V and a collector current limit of 100 mA. The unit includes built-in bias resistors with a nominal resistance of 10 kΩ and a ratio of 1.0 between the two internal paths. Key electrical characteristics include a minimum DC current gain (hFE) of 35 at 5 mA, a saturation voltage of 0.25 V at 10 mA, and a transition frequency of 150 MHz. Total power dissipation is rated at 150 mW.

Feature Summary

• Integrates two emitter-coupled transistors with built-in bias resistors into a single compact package to reduce mounting area and assembly costs.

Applications

• Digital circuits
• General electronic equipment such as office equipment and measuring instruments

Procurement Notes

Verify component authenticity through authorized distributors or official Panasonic channels. Confirm the specific ordering suffix matches the required packaging format. Check for RoHS compliance status and ensure the part number corresponds to the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when space constraints require dual NPN transistors with pre-biasing in a small footprint. Ensure the design accounts for the 150 mW total power dissipation limit and the 50 V voltage ratings. Verify that the 10 kΩ input resistance aligns with the driving circuit requirements for the intended digital logic levels.

Part Context

This device belongs to the XP0121 series of composite transistors designed for digital applications. It serves as a direct replacement for discrete setups requiring two matched NPN transistors with biasing resistors, offering a standardized solution for signal switching and amplification tasks in consumer electronics.

Replacement Considerations

The UNR2211 × 2 configuration is cited as a basic equivalent. Verify pinout compatibility and electrical parameter matching before substitution.
