Dual Schottky in a compact SOT-343
The BAS4007WH6327: This is a small-signal Schottky diode array with two independent junctions in a single SC-82A / SOT-343 package. Reverse leakage is 1 µA at 30 V. The dual configuration suits polarity protection, OR-ing, and signal steering in space-constrained designs.
What the 120 mA and 40 V ratings mean for your board
At 120 mA per diode, this part is sized for signal-level loads — think I²C bus clamping, logic-level translation, or low-current flyback catch diodes. Junction temperature tops out at 150 °C, which is typical for Schottky devices and allows operation in warm enclosures without derating.
