**Yangzhou Yangjie Elec Tech** · ESD And Surge Protection (TVS/ESD) · DO-214AA(SMB)

SMBJ36AQ from Yangzhou Yangjie Elec Tech, in a DO-214AA(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 | K | passive | Cathode of the uni-directional TVS diode, the end marked with the band; connect to the protected line, with a working peak reverse voltage VRWM of 36 V. |
| 2 | A | passive | Anode of the uni-directional TVS diode, the end without the band; usually connected to ground, with a breakdown voltage of 40.00 to 44.20 V and a maximum clamping voltage of 58.1 V at 10.3 A. |
