• Dual complementary configuration integrating one NPN and one PNP transistor in a single compact package
• Designed for small signal general purpose and switching applications
• Utilizes epitaxial planar process technology with epoxy molding

Applications

• Small signal general purpose circuits
• Electronic switching applications

Procurement Notes

This component has been officially transitioned to End of Life (EOL) status by Central Semiconductor Corp due to declining customer demand. While production has ceased, limited stock may still be available from authorized distributors. Buyers should verify current availability directly with suppliers before finalizing procurement plans.

Selection Notes

Select this component when a matched pair of NPN and PNP transistors is required in a minimal footprint. Ensure designs accommodate the specific voltage ratings: 40V for the NPN and 60V for the PNP collector-emitter breakdown. Verify that the thermal resistance of 357 °C/W aligns with the system's heat dissipation capabilities.

Part Context

The CMXT2207 belongs to the CMXT series of dual complementary transistors produced by Central Semiconductor Corp. This series provides integrated solutions for applications requiring paired NPN/PNP configurations without the need for discrete matching. The part utilizes the SUPERmini™ SOT-26 case for efficient surface mounting.

Replacement Considerations

No direct replacement part numbers are currently available from Central Semiconductor Corp. The manufacturer indicates that only existing stock remains for this discontinued item. Engineers must identify alternative components from other manufacturers if new production is required.
