PRODUCTION DATA
Two TVS diodes D3 and D4 are required at the input. The breakdown voltage of TVS in the positive side should be higher than the maximum system voltage 200 V. On the negative side clamping, diode D4 is used to clamp ISO 7637-2 pulse 1 and its selection is similar to procedure in TVS selection for 24-V Battery Systems. SMBJ150A for D3 and SMBJ33CA for D4 are recommended.
