What the 1500W rating means for your rail
The 1.5KE110CA-TP: That 1500W figure tells you how much transient energy it can absorb before the junction gives out — for a 94V standoff rail, a 152V clamp means the protected line sees less than 152V across the device during the surge event, which keeps downstream silicon inside its abs-max rating. The reverse standoff voltage of 94V is the DC or peak-AC voltage the diode can sit across without conducting appreciably. That 152V ceiling is the number to compare against the breakdown voltage of your downstream FETs or ICs.
Through-hole DO-201AE axial package — the same footprint as the common 1.5KE series. The axial leads let you solder it into a board or mount it point-to-point with sleeving. Available in Tape & Reel (TR) or Cut Tape (CT) — the TR option suits automated insertion for volume builds; CT works for prototype or repair quantities.
No power line protection rating (the part is not designed for AC mains primary-side clamping — it is a secondary-side transient suppressor for DC rails, signal lines, or low-voltage AC circuits).
