Active production — a 24V-rail TVS with AEC-Q101 pedigree
The 1.5SMC24CAHM3_A/H: That protection window keeps a 24 V bus within the safe operating area of downstream ICs during load-dump or inductive kickback events.
Package and board-fit for the DO-214AB footprint
Power line protection is not integrated — this is a standalone transient suppressor, not a rail-clamp array. The single bidirectional channel handles both positive and negative surges on one signal or power line, simplifying the BOM for a 24 V bus.
Sourcing posture for a current-production automotive-grade part
The AEC-Q101 qualification means the part has passed the automotive stress tests (temperature cycling, high-temperature reverse bias, ESD) and is traceable to a certified production line. For a 24 V automotive ECU or telecom power supply, this is the reliability floor the design requires.
