1.5 kW peak pulse in a DO-214AB footprint
The 1.5SMC12AHE3/57T: It clamps transients at 16.7 V maximum while conducting 89.8 A of peak pulse current. Reverse standoff voltage is 10.2 V, with a minimum breakdown of 11.4 V. The DO-214AB (SMC) package is surface-mount, requiring no through-hole — the copper pad area under the cathode tab sets the junction-to-ambient thermal resistance.
AEC-Q101 qualification for automotive lines
The series designation 'Automotive, AEC-Q101, 1.5SMC, TransZorb' means it carries the full automotive qualification trace — not just a commercial-grade die in an automotive package. For an ECU or battery-management clamp, this is the difference between a part that passes PPAP and one that does not.
Active lifecycle with no planned obsolescence
Vishay continues to manufacture the 1.5SMC series in the DO-214AB package, and the AEC-Q101 qualification ensures long-term supply for automotive program lifecycles. Sourced through authorized and independent distribution channels.
