# P4SMA6.8CA

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

P4SMA6.8CA from hongjiacheng, 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 | Bidirectional TVS terminal 1 (P4SMA6.8CA has no cathode band, so polarity is interchangeable); 5.8V reverse stand-off, 6.46-7.14V breakdown at 10mA, 10.5V max clamping at 38.10A. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (interchangeable with terminal 1, no cathode band on CA parts); 400W peak pulse power at 10/1000µs. |
