The 1.5KE120CAHB0G: The 114V minimum breakdown voltage ensures the device stays off during normal operation on a 102V standoff rail, only conducting when the line exceeds that threshold.
The bulk packaging means parts ship loose in tubes or bags — no tape-and-reel, so plan for manual or tube-fed insertion rather than automated pick-and-place.
Any bidirectional TVS diode in the 1.5KE series with the same 102V standoff voltage and DO-201 package is pin-compatible — the 1.5KE120CA is the base part number without the automotive qualification. The AEC-Q101 variant adds the reliability screening for automotive use, so for non-automotive designs the non-qualified version is a drop-in substitute.
As an AEC-Q101 qualified part, the 1.5KE120CAHB0G ships with the standard RoHS and REACH compliance declarations from Taiwan Semiconductor. The AEC-Q101 qualification itself is the key automotive reliability certification, covering temperature cycling, ESD, and parametric stress tests per the automotive-grade standard.
