IGBT ??

[Ed Lansinger]

The Motorola MGP20N40CL is a nice IGBT for ignition coil drive.
It has internal clamping diodes for voltage protection (400V)
and can handle 20 amps.  In practice, with peak coil currents
of 10A, it only needs a small heat sink.  You can drive it directly
from a 5V CMOS output.
