UMW SS14A
UMW · Schottky Diodes · SMA(DO-214AC)
UMW SS14A from UMW, in a SMA(DO-214AC). 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 | Pin 1 of the SMA molded body, which the datasheet marks by the color band denoting the cathode end; the SS14A is rated 40 V VRRM and 1 A average forward rectified current. |
| 2 | A | passive | Pin 2 of the SMA molded body, the opposite terminal to the color-banded cathode end; the SS14A is rated 40 V VRRM and 1 A average forward rectified current. |
