Product details

Automotive-grade Zener TVS for transient protection

The 1.5KE68H: The reverse standoff voltage is 55.1 V, with a minimum breakdown of 61.2 V — this window ensures the device stays off during normal operation but triggers before the protected circuitry sees damaging overvoltage.

AEC-Q101 qualification and temperature range

Qualified to AEC-Q101, the 1.5KE68H meets automotive-grade stress and reliability requirements — suitable for under-hood and chassis-domain applications where temperature swings and transient exposure are routine.
