TPSMC85A-VR
Littelfuse · TVS · DO-214AB(SMCJ)
TPSMC85A-VR 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 | K | passive | Cathode of the unidirectional TVS, marked by the color band, with VR 85.0 V stand-off, VBR 94.40 to 104.00 V at 1 mA and VC 137.0 V max at 11.0 A Ipp. |
| 2 | A | passive | Anode of the unidirectional TVS, which conducts forward with VF 3.5 V max at 100 A and carries up to 200 A IFSM. |
