**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · DO-214AC(SMA)

TPSMAJ6.5CA from TECH PUBLIC, in a DO-214AC(SMA). 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 with no polarity (the CA part has no cathode band), rated 6.5 V reverse stand-off, 7.22 V to 7.98 V breakdown at 10 mA, and 11.2 V maximum clamping at 35.7 A peak pulse current. |
| 2 | A2 | passive | Second bi-directional TVS terminal, interchangeable with the other, with 400 W minimum peak pulse power on a 10/1000 us waveform and 300 uA maximum reverse leakage at 6.5 V. |
