# SMAJ6.5CA

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

SMAJ6.5CA 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 (SMAJ6.5CA has no cathode band, so terminals are interchangeable), with VRWM 6.5V, VBR 7.22 to 7.98V at 10mA and VC 11.2V at IPP 35.7A. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (SMAJ6.5CA has no cathode band, so terminals are interchangeable), with VRWM 6.5V, VBR 7.22 to 7.98V at 10mA and VC 11.2V at IPP 35.7A. |
