1.5KE220CA from DOWO, 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 (no polarity band on the CA type); 1.5KE220CA has VRWM 185 V, VBR 209 to 231 V at 1 mA, and maximum clamping voltage 328 V at IPP 4.57 A. |
| 2 | A2 | passive | Second bidirectional TVS terminal, interchangeable with the other lead; the device handles 1500 W peak pulse power (10/1000 µs) and has maximum leakage of 1 µA at VRWM. |
