The 1.5SMC220CAHE3/9AT: In an automotive 24V system, a 328V clamp with 4.6A Ipp means the TVS absorbs roughly 1.5kJ of transient energy before the silicon reaches its thermal limit — adequate for ISO 7637-2 pulse 5a (load dump) suppression on moderate-capacitance bus lines.
Tape & Reel packaging suits high-volume pick-and-place.
