5 kW peak pulse capacity and clamping performance
The 5.0SMDJ100A-QH: The gap between the 100 V reverse standoff (the idle working voltage) and the 162 V clamping ceiling is the protection window: the part sits below standoff in normal operation and turns on hard when a transient pushes it past the 111 V minimum breakdown point.
AEC-Q101 qualification for automotive environments
The DO-214AB (SMC) package provides a solderable thermal interface suitable for board-level assembly on automotive control modules.
Target applications and protection role
Listed for automotive and telecom deployments — these are the two environments where load-dump, inductive kick, and ESD transients make a robust TVS a first-pass design requirement rather than an afterthought. The unidirectional polarity means it protects a single rail against positive-going spikes; a negative rail or bidirectional protection needs the dual-diode variant in the same series.
