24V standoff and 5kW peak pulse — the TVS selection axis
The 5-0SMDJ24A: The minimum breakdown of 26.7 V sits above the 24 V standoff, so the device stays off and leaks minimally under normal operation — it only turns on hard during an overvoltage event.
SMC/DO-214AB footprint and telecom deployment
The SMC (DO-214AB) package is the standard half-wave footprint for 5 kW TVS diodes — compatible with standard surface-mount pick-and-place lines and reflow profiles, with a land pattern that handles the die attach and thermal cycling the 150°C junction rating demands.
