MURS340 from Yangzhou Yangjie Elec Tech, in a SMC(DO-214AB). 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 terminal, marked by the color band on the package; the device blocks a repetitive peak reverse voltage (VRRM) of 400 V. |
| 2 | A | passive | Anode terminal, opposite the color band; it carries an average rectified output current of 3.0 A (100 A non-repetitive surge, IFSM) with a maximum VF of 1.25 V at 3.0 A. |
