The 1.5KE9.1AHE3_B/C: Its 7.7 V reverse standoff voltage means it sits across a 12 V nominal rail without conducting leakage, then avalanches at 8.65 V minimum and clamps transients to 13.4 V maximum at 117 A peak pulse current.
7.7 V reverse standoff means the diode will not conduct leakage current on a nominal 12 V bus. It starts avalanching at 8.65 V minimum and clamps the surge to 13.4 V maximum at 117 A — well below the typical 36 V load-dump survivability target for automotive ECUs.
As an AEC-Q101 qualified automotive-grade part, Vishay provides PPAP documentation, RoHS compliance declarations, and the full AEC-Q101 qualification test report. The TransZorb series is also UL recognized under the Vishay TVS component program.
