1.5KE150CA 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 1 (no cathode band on the bipolar CA version); working peak reverse voltage 128 V, breakdown 142.5 to 157.5 V at 1 mA, max clamping 207 V at 7.25 A. |
| 2 | A2 | passive | Bidirectional TVS terminal 2, interchangeable with the other terminal; 1500 W peak pulse power (10/1000 µs), max reverse leakage 1 µA at 128 V. |
