We can find no actual data on the part no. FN U7842. If anyone has any info on them we would be most grateful to receive it.
The term FN transistor paired with TO-3 typically references high-frequency or power transistors in metal can packages like the FN-1016 (often used in audio amplifiers) or standard TO-3 power types. The TO-3 is a classic metal-case package designed to bolt onto heat sinks for high-power handling.
Key Characteristics of TO-3 Transistors
- Metal body acts as the collector connection.
- Two pin-out leads (Base and Emitter) or case-integrated mount.
- High thermal dissipation capability.
- Requires mica or silicone insulators to isolate from grounded heat sinks.
Common Applications
- Linear and audio power amplifiers.
- Power supplies and voltage regulators.
- Heavy-duty industrial switching.
PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large distribution Co. and have been kept in storage for a time, they are however unused and in good condition, though as we say above, we have no actual specificatons for them.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
