XP0121400L

Overview

The XP01214L is a composite transistor featuring two NPN elements in an SMini5-G1 package. It integrates emitter-coupled transistors with built-in base resistors for digital circuits. Key electrical parameters include a collector-emitter voltage of 50V, collector current of 100mA, and total power dissipation of 150mW at 25°C. The transition frequency is 150MHz, and the DC current gain (hFE) is 80 minimum at 5mA/10V. Internal resistances are nominally 10kΩ with a ratio of R1/R2 between 0.17 and 0.25.

Feature Summary

Procurement Notes

Verify component status before procurement as this part may be discontinued or under maintenance plans. Confirm availability through official Panasonic Industry channels or authorized distributors. Ensure the latest datasheet revision matches design requirements. Check RoHS compliance documentation if required by specific regional regulations. Validate lead times and supply continuity prior to finalizing production schedules.

Selection Notes

Select this component when space constraints require dual transistor integration. Verify that the 50V rating and 100mA current capacity meet circuit demands. Consider the internal resistor values for biasing calculations. Ensure the SMini5-G1 package fits the PCB layout. Evaluate thermal performance given the 150mW power dissipation limit.

Part Context

This device belongs to the XP0121 series of composite transistors manufactured by Panasonic Industry. It utilizes silicon NPN epitaxial planar technology designed specifically for digital applications. The product complies with the RoHS Directive (EU 2002/95/EC). It is intended for standard applications in general-purpose electronics rather than specialized high-reliability sectors.

Replacement Considerations

Check for direct substitutes within the XP0121 series such as XP0121200L or XP0621400L. Verify pin compatibility and electrical characteristics match the original design. Consult Panasonic Industry for updated replacement recommendations if the part is discontinued.
