The 1.5SMC480AHE3_ALL: That 1.5 kW figure is the maximum energy the die can absorb in a single surge event — it defines the clamping capability, not the steady-state dissipation. This is the trigger point for the protection — below 456 V the diode is effectively an open circuit, so it does not load the signal line during normal operation.
Automotive qualification and temperature range
This part carries AEC-Q101 qualification, the automotive stress test standard for discrete semiconductors. The TransZorb® silicon avalanche technology is designed to handle repetitive surge events without degradation over the vehicle lifetime.
Package and board-fit for the DO-214AB (SMC) footprint
The package is rated for surface-mount reflow soldering and is supplied on Tape & Reel for automated pick-and-place.
