SMBJ13AQ
Yangzhou Yangjie Elec Tech · ESD And Surge Protection (TVS/ESD) · DO-214AA(SMB)
SMBJ13AQ 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, identified by the band on the package; SMBJ13AQ has VRWM 13.0 V, VBR 14.40-15.90 V at 1 mA and Vc 21.5 V at IPP 27.9 A. |
| 2 | A | passive | Anode of the uni-directional TVS diode at the end opposite the cathode band; no pin numbers or pin function table are printed in the datasheet, so this assignment follows the polarity note. |
