RUILON(Shenzhen Ruilongyuan Elec) · TVS · DO-201
1.5KE18CA 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 | Bidirectional TVS terminal 1 (no polarity, no cathode band on CA parts); 1.5KE18CA has 15.3V stand-off, 17.1-18.9V breakdown at 1mA and 25.2V max clamping at 59.5A (10/1000µs). |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (no polarity, interchangeable with terminal 1); 1500W peak pulse power at 10/1000µs, reverse leakage max 1µA at 15.3V. |
