XP0621400L

Overview

The XP0621400L is a composite transistor array manufactured by Panasonic Industry, featuring two integrated NPN pre-biased transistors within a single SMini6-G1 surface-mount package. Designed for digital circuits, it incorporates built-in base resistors to reduce mounting area and assembly costs. The device operates with a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per element. It delivers a transition frequency of 150MHz and a total power dissipation rating of 150mW at 25°C ambient temperature. The internal configuration utilizes a UNR2214 topology with an input resistance (R1) nominally set at 10kΩ.

Feature Summary

• Dual-element integration combining two NPN transistors with built-in biasing resistors into one compact package
• Designed specifically for digital circuit applications to minimize footprint and simplify assembly processes
• Utilizes the SMini6-G1 surface-mount package for efficient board space utilization

Applications

• General-purpose digital logic circuits
• Office equipment signal processing
• Communications equipment interface stages
• Household appliance control boards

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm RoHS compliance documentation aligns with EU Directive 2002/95/EC requirements. Ensure storage conditions respect the specified shelf life and damp-proof packaging protocols to prevent characteristic degradation prior to use.

Selection Notes

Select this component when dual NPN switching or buffering is required in space-constrained digital designs. Verify that the 10kΩ internal base resistor value matches the driving source impedance requirements. Ensure the 50V breakdown voltage exceeds the maximum operating voltage of the target application circuit.

Part Context

This part belongs to the XP0621 series of composite transistors from Panasonic Industry. It shares the same physical package and general electrical characteristics as variants like the XP0621200L and XP0621600L, differing primarily in the specific values of the integrated base resistors and resulting DC current gain specifications.

Replacement Considerations

Direct functional substitutes include the XP0621200L and XP0621600L. These alternatives share identical pinouts and packages but feature different internal resistor ratios and hFE values. Validate circuit compatibility regarding base drive currents before substitution.
