The Infineon BAS70-05E6327 is a dual Schottky diode with a common-cathode configuration in a surface-mount SOT-23-3 package. The 100 ps reverse recovery time makes it suitable for high-speed switching applications such as flyback clamping, polarity protection, and RF detector circuits. The small-signal Schottky construction keeps the forward voltage drop to 1 V at 15 mA, minimizing conduction loss in low-voltage rails.
With a 70 V maximum reverse voltage, this diode provides comfortable margin for 12 V and 24 V supply rails, including transients common in industrial and automotive environments. The reverse leakage is specified at 100 nA at 50 V, which is low enough to avoid significant standby drain in battery-powered circuits.
100 ps reverse recovery — fast enough for MHz switching
The 100 ps reverse recovery time is characteristic of Schottky diodes and eliminates the stored-charge delay seen in PN-junction diodes. This makes the BAS70-05E6327 a natural fit for high-frequency rectification, snubber clamping, and RF detector stages where switching speed directly affects efficiency or signal integrity.
SOT-23-3 package — rework-friendly footprint
The SOT-23-3 package (also listed as TO-236-3 and SC-59) is a standard three-lead surface-mount footprint. It is easy to hand-solder or rework with hot air, and the Infineon PG-SOT23-3-11 variant uses the same land pattern. The junction is rated for an operating temperature of 150°C, so the part can sit near warm components without derating concerns.
This is a standard small-signal Schottky diode that is widely stocked across the independent distribution channel.
