U1AQ
Yangzhou Yangjie Elec Tech · Fast Recovery / High Efficiency Diodes · SOD-123
U1AQ from Yangzhou Yangjie Elec Tech, in a SOD-123. 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, the end marked by the cathode line on the package body; rated for VRRM of 50 V (U1AQ), with 1.0 A average rectified output current. |
| 2 | A | passive | Anode, the end opposite the cathode line; forward voltage 0.92 V max at IF=1.0A, reverse recovery time 25 ns max. |
