1.5KE15CA from RUILON(Shenzhen Ruilongyuan Elec), in a DO-201. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Bi-directional (CA suffix) TVS terminal 1; the device is symmetric with no cathode band, 1500W peak pulse power at 10/1000μs, VRWM 12.8V, VBR 14.30-15.80V at 1mA, max clamping voltage 21.2V at 71.0A. |
| 2 | A2 | passive | Bi-directional (CA suffix) TVS terminal 2; the device is symmetric and either lead may be connected to the higher potential, with reverse leakage max 1μA at VRWM 12.8V. |
