HXY MOSFET · ESD And Surge Protection (TVS/ESD) · SOD-123FL
HSMF15AT13 from HXY MOSFET, in a SOD-123FL. 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 unidirectional TVS (marked by the cathode band on the body), connected to the protected line with a 15.0 V reverse stand-off voltage and 24.4 V maximum clamping voltage at 8.2 A. |
| 2 | A | passive | Anode of the unidirectional TVS (end opposite the cathode band), normally connected to ground, with a 16.7-18.5 V breakdown voltage at 1 mA test current. |
