Hi, i'm an auto electrician and i have just bought a Snap on test light from eBay. Its a LED test light EECT4H and the 4 diodes on the PCB are blown. Can anyone help me identify them. I have included the datasheet for the light and pictures of the diode and a diagram i did of the circuit. I believe the diode is size SOD323 if that is correct and i'm not sure if the diode is a standard diode or a zener as the lamp works at 6-12v?
