SUNMATE Elec · ESD And Surge Protection (TVS/ESD) · DO-27
1.5KE39CA from SUNMATE Elec, in a DO-27. 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 | Axial lead 1 of the bidirectional 1.5KE39CA TVS (VRWM 33.3 V, VBR 37.1-41.0 V at 1.0 mA, VC 53.9 V at IPP 28.2 A); polarity-free, interchangeable with the other lead, with no cathode band. |
| 2 | A2 | passive | Axial lead 2 of the bidirectional 1.5KE39CA TVS (1500 W peak pulse power on 10/1000µs); polarity-free, interchangeable with the other lead, marked with the device code only. |
