70 V / 70 mA common-cathode Schottky pair
The BAS7005WH6327XTSA1 from Infineon is a dual Schottky diode in a common-cathode configuration — two independent anodes sharing a single cathode pin, housed in a SC-70 (SOT-323) surface-mount package. Each diode is rated for 70 V reverse voltage and 70 mA average rectified current, making this a small-signal Schottky array, not a power rectifier. The headline spec that matters for fit is the 100 ps reverse recovery time — that is the absence of stored charge you get from a Schottky barrier versus a PN junction. In a high-frequency clamp or a steering diode for a fast-switching signal, that 100 ps means no reverse-recovery spike to ring the line.
Forward drop and leakage — the real-world tradeoffs
Forward voltage is 1 V maximum at 15 mA forward current. That is typical for a small-signal Schottky in this voltage class — not a low-Vf part, but the drop is predictable across the operating range. Reverse leakage is 100 nA maximum at 50 V reverse, which is low enough for battery-powered sense circuits at room temperature, but expect it to climb with junction temperature per the datasheet curve. The junction temperature rating is 150°C maximum — standard for this class, but the leakage at 125°C will be orders of magnitude higher than the 25°C figure. If the diode sits near a hot regulator or power stage, budget the leakage into your quiescent-current calculation.
The package is SC-70 (SOT-323), designated PG-SOT323 by Infineon. Three leads — the common cathode is pin 2, anodes on pins 1 and 3. The footprint is standard SOT-323, shared with countless small-signal transistors and diodes, so the copper land pattern is well established. No exposed pad, no thermal vias needed at 70 mA per diode.
