**Bencent** · TVS · SMB

BV-SMBJ6.5A from Bencent, in a SMB. 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 of the unidirectional TVS (VR 6.5V stand-off, VBR 7.22-7.98V at 10mA, VC 11.2V at IPP 53.6A); connect to the protected positive line. |
| 2 | A | passive | Anode of the unidirectional TVS; connect to ground or the return line of the protected circuit. |

## CAD (KiCad official)

- Symbol: `BV-SMBJ6.5A`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `bv-smbj6-5a-etched.step` / `bv-smbj6-5a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bv-smbj6-5a.step` / `bv-smbj6-5a.glb` are the bare package body.
