1.5SMC6.8CA from Littelfuse, in a DO-214AB. 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 | Terminal 1 | passive | Bidirectional TVS terminal with no polarity (no cathode band), standing off 5.80 V (VR), breaking down at 6.45-7.14 V at 10 mA, and clamping at 10.5 V max at 144.8 A Ipp. |
| 2 | Terminal 2 | passive | Second bidirectional TVS terminal, interchangeable with the other terminal, with 1500 W peak pulse power (10/1000 µs) and 1000 µA max leakage at VR 5.80 V. |
