I found this component t4N shorted, lucky that time i got scrap unit to get the spare part. But I want to buy this for future spare part. I can't identify the part number, cant find even using google.

I found this component shorted when troubleshooting this unit: https://elex518.blogspot.com/2019/02/chiller-controller-psc-4400-lam-rainbow.html
 

The only component in SOT23 package with 4N as it's code that I can find is a transistor L2SC4083. It is described as an audio transistor but I can't find a datasheet.
Note: it is NOT the same device as a 2SC4083 which is a microwave amplifier transistor.

Thanks betwixt...have tried to search also the datasheet, but have no luck. Really stuck from here already, I would like to find replacement/substitute but a bit difficult without knowing the part number of t4N.
