Series Schottky pair in a standard SOT-23 footprint
The BAS4004E6327HTSA1 is a Schottky diode array from Infineon, integrating two 40 V, 120 mA diodes in a common-cathode series configuration within a single SOT-23-3 package. Rated for a maximum reverse voltage of 40 V and an average rectified current of 120 mA per diode, it targets low-current signal rectification, clamping, and OR-ing in compact designs.
Switching speed and leakage at 30 V reverse bias
A reverse recovery time of 100 ps makes this part suitable for high-frequency switching applications up to several hundred MHz, where a standard PN-junction diode would introduce excessive switching loss. Reverse leakage is specified at 1 µA maximum at 30 V reverse bias — a figure that rises with junction temperature, so the effective leakage at 85 °C ambient should be derated per the Infineon datasheet curve. Forward voltage is 1 V maximum at 40 mA forward current, a typical Schottky Vf for this current class; the lower Vf vs a PN diode reduces conduction loss in low-voltage rails.
SOT-23-3 surface-mount package and tape-and-reel delivery
Housed in the industry-standard SOT-23-3 (PG-SOT23) package, the BAS4004E6327HTSA1 occupies a 2.9 mm × 1.3 mm footprint with 0.95 mm pin pitch — compatible with existing SOT-23 land patterns for reflow assembly. Supplied on tape and reel (Cut Tape also available), it integrates directly into automated pick-and-place lines without process change.
Active production, ROHS3 compliant, multi-source distribution
As an active, catalog-listed part, it is available through Infineon's authorized distribution network and independent channels; pricing and lead time are confirmed at RFQ against the BOM quantity.
