2N2652

Overview

The Central Semiconductor Corp 2N2652 is a dual NPN amplifier and switch transistor housed in a TO-78 metal case. It features a collector-base voltage of 100V, a collector-emitter voltage of 60V, and a maximum collector current of 500mA. The device provides a minimum DC current gain (hFE) of 150 at 50mA and a typical transition frequency (fT) of 50MHz. Total power dissipation is rated at 600mW at 25°C ambient temperature with equal power sharing between the two dies.

Feature Summary

• Dual NPN configuration within a single hermetic metal package
• Designed for general-purpose amplification and switching applications
• High current gain capability suitable for driver stages

Applications

• General purpose signal amplification
• Electronic switching circuits
• Driver stages for power transistors

Procurement Notes

Verify End-of-Life status before procurement. The manufacturer has discontinued all devices in the TO-78 package. Confirm if existing inventory remains available or if alternative sourcing from other manufacturers is required for production needs.

Selection Notes

Select this component only if legacy TO-78 packaging is mandatory for the design. Evaluate thermal constraints carefully as the 600mW rating requires equal power distribution between the internal dies. Ensure replacement strategies are defined due to discontinuation.

Part Context

This component belongs to a family of dual transistors manufactured by Central Semiconductor Corp. All units in the TO-78 case style have been officially classified as End of Life. The manufacturer indicates no direct replacement part numbers are available for this specific model.

Replacement Considerations

No official replacement part numbers are listed by the manufacturer. Designers must identify equivalent dual NPN transistors in different packages or source surplus stock, as the TO-78 package line is fully discontinued.
