IGN1A IGBT Coils have a 19 amp IGBT ignitor built in and can be driven with a 5 volt logic level output Normally, we use them for a distributorless ignition as a coil per plug application, however they can be fired sequentially or every crank revolution (wasted spark coil per plug). If used as a single coil with a distributor, you may need to run a bit less dwell to prevent heat buildup from being an issue. Maximum recommended duty cycle is 40%.
The coil dwell starts when a 5 volt signal is applied to pin A and the coil fires when the voltage drops to zero. The signal is similar to an LSx coil, although it does need a bit more current to trigger.

Care must be taken with power supply due to the high current these units can pull. Some OEM wiring may not be capable of maintaining this and we recommend 16AWG M22759/32 wire for the most reliable solution.
