TVS for OV Protection

TVS for OV Protection



Design Notes:

Protection Application:
For the SMPS power supply, the Capacitor at PFC could be explosive due to transient voltage. An TVS diode could be placed in parallel to the to capacitor at PFC for over voltage protection.
Solution Description:
The TVS diode should be selected based on the line voltage, nominal load current. Typical part number used as 1.5SMC400A.
