Littelfuse · TVS · DO-214AA
TPSMB26CA-VR from Littelfuse, in a DO-214AA. 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 (CA) TVS terminal with no polarity; stand-off voltage VR 26.0 V, breakdown 28.90-31.90 V at 1 mA, max clamping 42.1 V at 14.3 A Ipp. |
| 2 | Terminal 2 | passive | Second bidirectional TVS terminal, interchangeable with terminal 1 because the part has no cathode band; 600 W peak pulse power at 10/1000µs. |
