Littelfuse · TVS · DO-214AB(SMCJ)
SMDJ8.0CA 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 | Terminal 1 | passive | Bidirectional TVS terminal with no polarity (no cathode band on CA versions); stand-off voltage 8.0 V, breakdown 8.89-9.83 V at 1 mA, max clamping 13.6 V at 220.6 A (10/1000µs). |
| 2 | Terminal 2 | passive | Bidirectional TVS terminal interchangeable with the other terminal; 3000 W peak pulse power at 10/1000µs, max reverse leakage 50 µA at 8.0 V. |
