Hi Experts,
I have been encountering diode protection burn-out, thats the diode D1 OPN:1N4148W-E3-08 got burnt and failed. Further x-ray investigation shows internal wires melted and burnt die which leads to suggestion of electrical over-stress and large surge current. I attached the schematic enclosed.
Please advise what has went wrong and what additional circuit should be included to prevent such burnt-out from happening again. Thanks
