Automotive Ignition Transistor

Automotive Ignition Transistor

Automotive Ignition Transistor

(OP)
I want to use the POINTS of an early (6v) Automobile to switch a SEMICONDUCTOR controling the ignition coil . What would be a good useable device its probably been done before I have seen 12v systems but not 6v applications. Any device numbers would be helpful.

RE: Automotive Ignition Transistor

IGBT!  Do a search and look through those,  I guarentee that those will work in your application, since they are used by several of the biggest auto makers in the US.

RE: Automotive Ignition Transistor

Hi melone, I have not seen an IGBT that swiches with 6v, do you have a part number?. A logic drive MOSFET would seem a better choice.

RE: Automotive Ignition Transistor

The IGBT's that we use are logic level gate drive.  I will have to do some searching to find the part numbers, but try looking at On semiconductors or Harris semiconductors.

RE: Automotive Ignition Transistor

There are plenty of "sensitive gate" IGBTs in the world.  I use then when the job calls for them, but they are usually 25 to 50% more expensive in small volumes.
