CMXT2207 TR PBFREE

Overview

The CMXT2207 is a dual complementary silicon transistor manufactured by Central Semiconductor Corp. in the SOT-26 surface mount package. It consists of an NPN and PNP transistor pair designed for small signal general purpose and switching applications. The device features a collector-base voltage rating of 75V for the NPN side and 60V for the PNP side, with continuous collector currents up to 600mA. Power dissipation is rated at 350mW, and the operating junction temperature range spans from -65°C to +150°C.

Feature Summary

• Dual complementary configuration integrating NPN and PNP transistors into a single compact surface mount package.
• Designed specifically for small signal general purpose operations and high-speed switching applications.
• Utilizes epitaxial planar process technology within an epoxy molded SUPERmini™ case.

Applications

• Small signal amplification circuits
• General purpose switching applications
• Complementary output stages

Procurement Notes

This component has been officially transitioned to End of Life (EOL) status by Central Semiconductor Corp. Current availability is restricted to existing stock only, as production has ceased. Buyers should verify specific inventory levels directly with authorized distributors or the manufacturer's sales team, as standard ordering channels may no longer accept new purchase orders for this discontinued part number.

Selection Notes

Engineers selecting this component must account for its discontinuation status when designing new products. While the electrical characteristics remain suitable for legacy designs requiring a dual complementary BJT pair in an SOT-26 footprint, long-term supply chain stability cannot be guaranteed. Design reviews should prioritize identifying alternative components that offer equivalent pinouts and performance metrics to ensure future manufacturability.

Part Context

The CMXT2207 belongs to Central Semiconductor’s SUPERmini™ series of discrete semiconductors. This series focuses on providing high-density packaging solutions for various transistor types. As a dual complementary device, it serves as a space-saving alternative to using separate NPN and PNP transistors in circuit layouts requiring matched or complementary switching behaviors.

Replacement Considerations

No direct replacement part numbers are currently available from Central Semiconductor Corp. for this model. The manufacturer indicates that no substitutes exist and advises contacting [email protected] for assistance in locating alternate sources or compatible third-party equivalents.
