1.5KE12CA 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 (CA suffix) terminal 1 of the axial-lead TVS; no polarity, either lead may connect to the protected line, with 1500 W peak pulse power (10/1000 µs). |
| 2 | A2 | passive | Bidirectional (CA suffix) terminal 2 of the axial-lead TVS; no polarity, interchangeable with the other lead, with VRWM 10.2 V and VBR 11.40 to 12.60 V at 1 mA for 1.5KE12CA. |
