TPSMC26CA-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 | A1 | passive | Bi-directional TVS terminal 1 (TPSMC26CA-VR, no polarity, no cathode band): 26.0V reverse standoff, 28.90-31.90V breakdown at 1mA, 42.1V max clamping at 35.7A peak pulse current (10/1000µs). |
| 2 | A2 | passive | Bi-directional TVS terminal 2 (TPSMC26CA-VR, no polarity, no cathode band): interchangeable with terminal 1, 1500W peak pulse power at 10/1000µs. |
