# BAS70-04Q-13-F

**Diodes Incorporated** · Schottky Diodes · SOT-23-3

BAS70-04Q-13-F from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | passive | Anode of diode 1. Connects to the P-side of the first Schottky junction; cathode of this diode is the common cathode on pin 3. Max continuous forward current 70mA, forward voltage ~0.41V @ 1mA. |
| 2 | A2 | passive | Anode of diode 2. Connects to the P-side of the second Schottky junction; cathode of this diode is tied to the common cathode on pin 3. Max continuous forward current 70mA, forward voltage ~0.41V @ 1mA. |
| 3 | K | passive | Common cathode. Shared N-side of both Schottky diodes (BAS70-04 is a common-cathode dual configuration). Reverse breakdown voltage 70V, reverse leakage 0.1µA typ. @ 25°C. |
