# BAS70-04-E3-08

**Vishay Intertech** · Schottky Diodes · SOT-23

BAS70-04-E3-08 from Vishay Intertech, in a SOT-23. 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 | A1 | passive | Anode of the first Schottky diode in the series pair (BAS70-04 top view, pin 1 bottom left); VRRM 70 V, IF 200 mA. |
| 2 | K2 | passive | Cathode of the second Schottky diode in the series pair (BAS70-04 top view, pin 2 bottom right); VRRM 70 V, IF 200 mA. |
| 3 | K1/A2 | passive | Center node joining the cathode of the first diode to the anode of the second diode in the serial dual configuration (top pin). |
