3 leg device

Hi
I'm trying to identify an IC.
It is physically located next to a 2SD1071 in a CDI device.
The IC is green, 3 legs and flat. Its about the same size as a
7805 voltage regulator.
The only numbers I can make out are 1356
The 6 may be a G. There is a character before the 1
but I can't make it out.
This IC is on a CDI card for a motor bike
I'd be grateful for any info
Regards
Harry

This is only a 'possible'.... could the character before the 1 be an A?

I think you've cracked it. The 2SA looks promising and I've not yet checked the 2SD.
Many thanks
