XP0121300L

Overview

The Panasonic XP0121300L is a composite transistor featuring two NPN elements in an SMini5-G1 package. It operates with a collector-emitter voltage of 50V and a maximum collector current of 100mA. The device includes built-in base resistors, typically 47kΩ, to simplify circuit design. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 5mA and a transition frequency of 150MHz. Total power dissipation is rated at 150mW, making it suitable for digital logic applications requiring compact surface-mount solutions.

Feature Summary

• Integrates two emitter-coupled NPN transistors into a single surface-mount package
• Includes built-in base resistors to reduce external component count
• Designed specifically for digital circuit applications

Applications

• Digital logic circuits
• General electronic equipment
• Communications equipment

Procurement Notes

Verify the specific revision status before procurement as this component is listed under maintenance or discontinued categories by the manufacturer. Confirm that the SMini5-G1 package dimensions align with existing PCB footprints. Ensure compliance with RoHS directives if required for the target market. Request the latest product standards directly from Panasonic Industry to verify current specifications prior to finalizing orders.

Selection Notes

Select this component when space constraints require integrating two matched NPN transistors with biasing resistors. The 50V rating and 100mA current capacity suit low-power digital switching tasks. Verify that the 150mW total power dissipation meets thermal requirements for the intended enclosure. Consider the 47kΩ internal resistance values for base drive calculations to ensure proper saturation levels in the application.

Part Context

This part belongs to the XP0121 series of composite transistors manufactured by Panasonic Industry. These devices are silicon NPN epitaxial planar types designed to replace discrete transistor pairs. The series offers reduced mounting area and assembly costs compared to using individual components. The XP0121300L specifically denotes the variant with 47kΩ base resistors.

Replacement Considerations

Direct substitutes may include other dual NPN pre-biased transistors in compatible packages such as SC-70-5 or SOT-353. Verify pinout compatibility and resistor values when considering alternatives from other manufacturers. Ensure replacement parts meet the same 50V and 100mA ratings.
