**Shandong Jingdao Microelectronics** · ESD And Surge Protection (TVS/ESD) · SMA

SMAJ6.5A from Shandong Jingdao Microelectronics, in a 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 | Cathode | passive | Cathode terminal of the SMAJ TVS diode, which is the pin that sits at the positive side of the clamp in the unipolar (UNI) version used by SMAJ6.5A. |
| 2 | Anode | passive | Anode terminal of the SMAJ TVS diode, connected to the opposite side of the clamp from the cathode in the unipolar (UNI) version used by SMAJ6.5A. |

## CAD (KiCad official)

- Symbol: `SMAJ6.5A`
- Footprint: `Diode_SMD:D_SMA`
- 3D model: SMA (KiCad packages3D, STEP)
- 3D model files: `smaj6-5a-etched.step` / `smaj6-5a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smaj6-5a.step` / `smaj6-5a.glb` are the bare package body.
