What the 1500W rating means for the board
The 1.5KE180CA B0G: The 154 V reverse standoff voltage defines the normal operating rail — the protected line should never exceed this in steady state. Breakdown starts at 171 V minimum, and clamping is guaranteed at 246 V maximum at the rated current. Single bidirectional channel means the same device protects against positive and negative surges, so polarity orientation during installation is not critical — a practical advantage for field repairs where the board may not be marked clearly.
Through-hole axial package — field-swappable with basic tools
Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), this is a through-hole part that can be replaced on site with a soldering iron and solder wick. No hot-air station or reflow oven needed. The axial leads are clearly polarized by the body marking — the cathode band is present even on a bidirectional device, though the bidirectional construction means it works either way.
General-purpose application fit
Classified for general purpose applications, this TVS diode is not locked into a single industry standard — it works equally well in industrial power supplies, telecom line cards, automotive load-dump protection, and consumer AC-DC converters.
