Product details

Automotive-grade transient suppression in a through-hole package

The 1.5KE7.5CAH: The reverse standoff voltage is 6.4V, and breakdown occurs between 7.13V minimum. This makes it suited for protecting 5V or 6V rails in 12V automotive electrical systems against load-dump and inductive-load transients.

The 139A peak pulse current at the clamping voltage confirms the diode can shunt high transient currents without exceeding junction temperature. The AEC-Q101 qualification includes stress tests for temperature cycling, high-temperature reverse bias, and ESD — essential for Tier-1 PPAP submissions.

Sourced through independent distribution channels. The AEC-Q101 documentation and RoHS/REACH compliance certificates are available with the order.
