Product Overview
RCA 2N6468 is a silicon PNP bipolar power transistor built in the classic TO-66 metal package. Designed for medium-power switching and linear service, it supports applications up to 120 V and 4 A with proper heatsinking. With a power dissipation rating of 40 W and transition frequency around 5 MHz, it bridges low-frequency power control and moderate-speed signal stages. Originally used in regulated power supplies, industrial controls, and driver stages, it remains a practical choice for restoration, repair, and discrete power design.
The TO-66 metal can provides solid thermal transfer when chassis-mounted, making it suitable for series pass regulation and high-voltage PNP switching roles. Collector connection is through the case, with base and emitter on the two leads, following standard TO-66 conventions.

Frequently Asked Questions
Is this suitable for a 120 V linear power supply design?
It is rated up to 120 V collector-emitter and 4 A continuous collector current. Proper heatsinking is required to approach the 40 W dissipation limit.
What package style is used?
It uses the TO-66 metal can package. The collector is connected to the case, with base and emitter on the two leads. An insulating kit is typically used if electrical isolation from the heatsink is required.
Can this replace other 120 V, 4 A PNP TO-66 transistors?
It shares common ratings with other 120 V, 4 A, 40 W PNP TO-66 devices. Electrical characteristics and pin configuration should always be verified against your specific circuit before substitution.
Has this part been tested?
This listing is for unused, New Old Stock components. They have not been pulled from service and show no signs of prior installation.
Is more stock available?
Inventory is limited to what is currently on hand from this acquisition. Once depleted, restocking is unlikely.
RCA’s power semiconductors helped define early solid-state power control. If you are keeping legacy gear alive or building with discrete muscle, this one is ready for its next circuit.
