Product details

Automotive-grade qualification and application scope

The 1.5SMC51CAHM3_A/H: This part carries AEC-Q101 qualification, making it suitable for automotive electronic modules that require documented reliability screening per the automotive stress-test qualification standard. The series designation 'Automotive, AEC-Q101, 1.5SMC, TransZorb®' confirms it meets the temperature cycling, ESD, and humidity bias requirements for Tier-1 supply. Listed applications include Automotive and Telecom — the 43.6V standoff voltage aligns with 48V telecom battery plants and 48V automotive mild-hybrid bus protection. The bidirectional configuration (1 channel) clamps both polarities with a single device, reducing component count on the rail.
