XN0121600L

Overview

The Panasonic XN01216 is a composite transistor consisting of two NPN silicon epitaxial planar transistors in one SC-74A package. It features emitter-coupled elements with a built-in bias resistor ratio of 4.7. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a maximum collector current (IC) of 100 mA, and a total power dissipation (PT) of 300 mW at 25°C. The forward current transfer ratio (hFE) ranges from 160 to 460 at IC = 5 mA. Transition frequency (fT) is 150 MHz. Input resistance is 4.7 kΩ ±30%. Operating junction temperature reaches 150°C.

Feature Summary

• Two NPN elements incorporated into a single package for area reduction
• Built-in bias resistor simplifies circuit design
• High-speed switching capability suitable for digital applications

Applications

• Switching circuits

Procurement Notes

Verify the specific ordering suffix against the official Panasonic Semiconductor website or authorized distributor catalogs before purchase. Confirm the component lifecycle status, as this part may be subject to maintenance or discontinuation plans. Ensure the package type matches the required PCB footprint and soldering profile specifications.

Selection Notes

Select this component when space constraints require integrating two matched transistors with a fixed bias ratio. Verify that the 50 V collector-emitter voltage and 100 mA current ratings exceed the application's peak requirements. Consider the thermal management needs relative to the 300 mW total power dissipation limit in the operating environment.

Part Context

This device belongs to the XN series of composite transistors manufactured by Panasonic Electronic Components. These devices integrate multiple discrete semiconductor functions into compact surface-mount packages to reduce assembly costs and board space. The XN01216 specifically utilizes an SC-74A (Mini5-G1) outline.

Replacement Considerations

Check for direct cross-references such as UNR2216 equivalents or other dual NPN composite transistors with similar hFE ratios and voltage ratings. Verify pinout compatibility and thermal characteristics before substituting.
