Littelfuse · TVS · DO-214AB(SMCJ)
SMDJ8.0A from Littelfuse, in a DO-214AB(SMCJ). 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 | Cathode | passive | Cathode terminal of the unidirectional TVS (marked by the color band); stand-off voltage VR 8.0 V, breakdown 8.89-9.83 V at 1 mA, max clamping 13.6 V at 220.6 A (10/1000µs). |
| 2 | Anode | passive | Anode terminal of the unidirectional TVS, opposite the cathode band; max forward voltage VF 3.5 V at 100 A for single-die parts. |
