An ignition circuit for a spark plug includes an IGBT switch with a foldback clamp circuit. The foldback clamp has a first high clamp voltage for a first short interval to fire the spark plug, followed by a lower clamp voltage. The power dissipation of the IGBT switch is therefore substantially reduced.
