# SB3100

**SMC Sangdest Microelectronicstronic Nanjing** · Schottky Diodes · DO-201AD

SB3100 from SMC Sangdest Microelectronicstronic Nanjing, in a DO-201AD. 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 lead on the end of the body marked with the cathode band; it is the positive terminal in forward conduction and blocks up to VRRM = 100 V. |
| 2 | A | passive | Anode, the lead on the end of the body opposite the cathode band; it carries up to 3 A average rectified forward current (IF(AV), 50% duty cycle at TC = 105°C). |
