Clamping voltage and breakdown margin
The 1.5KE7.5CAHR0G: Reverse standoff is 6.4 V typical; the device starts to conduct at 7.13 V minimum breakdown, clamping the transient at 11.3 V maximum when the peak current hits 139 A. A single bidirectional channel means the same part clamps positive and negative surges symmetrically — no polarity concern during assembly, which simplifies pick-and-place for the axial leaded body. The full operating junction temperature range spans -55 °C to 175 °C, covering the cold-crank and hot-soak extremes an automotive module sees on the engine bay or firewall.
Package and board integration
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE7.5CAHR0G mounts through hole — the lead bend and body clearance must fit the board's hole pattern and keep the transient current path short back to the supply rail.
Sourcing and lifecycle posture
No pin-compatible second-source or successor cross-reference is documented for this exact order code.
