XN0F25600L

Overview

The XN0F256 is a composite transistor featuring two silicon NPN epitaxial planar elements integrated into a single package. It consists of collector-coupled transistors with built-in resistors, designed for muting applications. The device operates within a collector-emitter voltage range of 20 V and supports a maximum collector current of 600 mA. Key electrical characteristics include a forward current transfer ratio (hFE) ranging from 100 to 600 at 50 mA, a transition frequency of 200 MHz, and a low collector-emitter saturation voltage of 80 mV under specified conditions. The internal resistor value is nominally 4.7 kΩ with a ±30% tolerance.

Feature Summary

• Dual-element integration combining two transistors into one package to reduce mounting area and assembly costs.
• Built-in base resistor configuration simplifies circuit design by eliminating external components.
• Low collector-emitter saturation voltage ensures efficient switching performance.
• High forward current transfer ratio suitable for amplification and switching tasks.

Applications

• Muting circuits in audio equipment
• General-purpose switching applications
• Amplifier stages requiring compact footprint

Procurement Notes

Verify the current lifecycle status before procurement, as the datasheet indicates maintenance or discontinued classifications. Confirm package availability and lead times directly with authorized distributors or Panasonic sales representatives. Ensure compliance with RoHS directives if required for your specific application environment.

Selection Notes

Select this component when space constraints require dual-transistor functionality in a minimal footprint. Consider the 4.7 kΩ internal resistor value for biasing requirements. Evaluate the 20 V collector-emitter voltage limit against peak operating voltages. The 600 mA current rating should accommodate load demands without exceeding thermal limits.

Part Context

The XN0F256 belongs to Panasonic's composite transistor family, specifically designed for applications needing multiple active elements in a single housing. It utilizes an EIAJ SC-74 Mini6-G1 package, providing a compact solution compared to discrete implementations. This integration aids in reducing board space and simplifying assembly processes.

Replacement Considerations

Consult official replacement lists on the Panasonic semiconductor website for verified substitutes. Cross-reference pinouts and electrical parameters carefully when considering alternatives from other manufacturers to ensure compatibility with existing circuit designs.
