What the 1500W rating means for a 85.5V rail
The 1.5KE100CA A0G: So if you are protecting a 85.5V nominal bus (common in 48V telecom rectifiers or 72V battery systems after a boost converter), this part holds the surge below the downstream components' abs-max rating.
Field-swappable through-hole package
Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), this is a through-hole part. No hot-air station needed — a standard soldering iron swaps it on a board. The axial leads are easy to orient: the cathode band is the only polarity mark, and since it is bidirectional, orientation does not matter for the protection function (it clamps both polarities). Mounting it in a panel or on a terminal block is straightforward with the lead spacing typical of DO-201 footprints.
That covers automotive underhood (125°C ambient with margin), industrial enclosures near ovens or motors, and outdoor telecom cabinets that see both desert heat and arctic cold. The 175°C TJ ceiling means the die itself can spike hot during a surge without immediate failure, as long as the average power stays within the derating curve.
Sourcing posture: quoted to order
Active and available through independent distribution channels. The part ships in Tape & Box (TB) packaging, suitable for both hand-insertion and auto-insertion machines that handle axial components.
