[sdiy] Designator on zener 362?

That's what it looks like. I'm thinking there was a 3.6 volt value 
but...that doesn't seem likely as I draw out the circuit.  It's fried 
and so was the resistor in series; someting that certainly would happen 
I'd think if it were that. It's for an expensive charger for someone but 
just thought someone in here might recognize that style of designation.  
Thanks guys.  Hitachi is no help.  And not finding anything googling.

The circuit has current going through the zener to a 100ohm resistor to 
ground, with that point of connection feeding another 100ohm to an opto 
isolator led.

So if the charger is outputting 14V it would have like 9V at least 
across the resistor which would fry it's little 1/4W essence very 
quickly.  .8W at that voltage of course.  And the output says 7.x to 14V 
or something like that on it.   From what I drew out I think that 
circuit is designed to turn on the opto which controls an additional 
coil on the primary...when it detects that the battery being hooked up 
has more than 8V on it or whatever.  -Bob
