Power dissipation of SMBJ30A/CA for DC operation below clamping voltage

2022-12-12
Hi ST Team, i use the SMBJ30A/CA but how much current will be flow if a DC voltage of 40 volt is applied? It must be larger than IBR = 1 mA given in the datasheet. However, there isn't any info for DC operation if a DC voltage above VBR but below VCL...
