What this Schottky pair does on the board
The Infineon BAS70-06WH6327 is a dual Schottky diode in a common-anode configuration, housed in a PG-SOT323-3 (SC-70) surface-mount package. The 100 ps reverse recovery time makes it suited for high-speed switching and RF detector circuits where the diode's capacitance and recovery shape the waveform.
The 70 V reverse voltage rating covers 48 V telecom rails and 24 V industrial buses with margin. The 70 mA forward current per diode is the continuous rating — fine for signal-level clamping, ESD protection, or small-signal rectification. The 1 V forward drop at 15 mA is typical for a Schottky of this die size; if you need lower Vf at higher current, look at a larger package like SOT-23. The 100 ps trr is fast enough for RF detector diodes and high-speed switching up into the UHF band. Off-state leakage is specified at 100 nA at 50 V reverse bias, which is low enough for battery-powered sense circuits.
