Randomly resetting a micro. No useful info found TO92 device anyone hazard an idea of spec ? hold off for how long ? Could this be a hybrid construction with some electrolyted device inside. ? A lot of green corrossion from something that would seem to have leaked from inside this device, encrustation on the underside of its body and then green corrossion products associated with copper jumpers etc nearby

VHI prefix product code for Mitsumi device PST600K, data found , no mention of a liquid inside. Anyone come across a corrossive liquid break down product, from old age or whatever?

What did this come from? I can look up by mode and part number. Also include the circuit designation if you can.
Thx, Dan

+++++It is in a 1998 Sharp VC MH711 vcr with a favoured feature so repair rather than any old replacement. It is IC703 5V, 2.5V trigger. I'm more intrigued where this liquid came from, down the legs of the device and then pooled around it on the pcb. No hole in th e case above it anywhere for any user spilt liquid to gain entry
