SMA6J58A
Littelfuse · TVS · SMA(DO-214AC)
SMA6J58A from Littelfuse, in a SMA(DO-214AC). 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 | K | passive | Cathode of the unidirectional TVS, marked by the color band, with VR 58 V, VBR 64.4-71.2 V at 1 mA and VC 93.6 V at 6.7 A Ipp. |
| 2 | A | passive | Anode of the unidirectional TVS, the terminal opposite the cathode band, which conducts forward with VF up to 3.5 V at 25 A. |
