# SMBJ36A-JSM

**JSMSEMI** · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

SMBJ36A-JSM from JSMSEMI, in a SMB(DO-214AA). 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, marked by the cathode band on the body; the band denotes a uni-directional device, which matches the unidirectional SMBJ36A part. |
| 2 | Anode | passive | Anode terminal, the terminal without the cathode band, used with the cathode to clamp transients at the rated standoff voltage VRWM of 36 V (breakdown 40.0 to 44.2 V, max clamping 58.1 V at Ipp 10.4 A). |

## CAD (KiCad official)

- Symbol: `SMBJ36A-JSM`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `smbj36a-jsm-etched.step` / `smbj36a-jsm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smbj36a-jsm.step` / `smbj36a-jsm.glb` are the bare package body.
