The Infineon BAS70-07E6433 packs two independent Schottky diodes in a single PG-SOT143-4 surface-mount package, each rated for 70 V reverse voltage and 70 mA average rectified current. The 100 ps reverse recovery time is the headline number here — that sub-nanosecond switching speed makes this diode a natural fit for high-frequency clamping, flyback snubbing, and OR-ing in low-power DC-DC converters where every nanosecond of dead time costs efficiency. Reverse leakage is specified at 100 nA at 50 V, which is tight enough to avoid draining a battery in a wake-up circuit or a sample-and-hold front end.
Dual-diode configuration — board-space savings without the routing headache
Two independent Schottky diodes in a four-pin SOT-143 package means you get two separate signal paths on one footprint. That is useful for dual-rail ESD clamping (one diode per rail), for building a low-loss OR-ing stage from two supplies, or for a full-wave rectifier in a low-current AC sense circuit. The independent cathode and anode connections give layout flexibility — no common-cathode or common-anode strapping to work around.
Infineon lists the BAS70-07E6433 as Active.
