Schottky diode for low-voltage rectification and clamping
The Infineon BAT54WH6327XTSA1 is a Schottky diode rated for 30 V reverse voltage and 200 mA average rectified current, housed in a surface-mount SC-70 (SOT-323) package. Its 800 mV forward voltage at 100 mA and 5 ns reverse recovery time suit it for low-voltage rectification, freewheeling, and clamping applications in compact designs.

Key ratings for the BOM decision
The 30 V reverse voltage and 200 mA forward current define the operating envelope — this is a low-voltage, low-current Schottky. The 800 mV forward drop at 100 mA is higher than some Schottky types; if efficiency at low current is critical, compare against parts with lower Vf at the same current. The 5 ns trr is fast enough for switching up to several MHz in signal-level rectification. Junction temperature maxes at 150 °C, typical for this class.
Package and footprint
The SC-70 (SOT-323) package is a three-lead surface-mount body, 2.0 mm × 1.25 mm typical, with a 0.65 mm lead pitch. The Infineon supplier device package is PG-SOT323. This footprint is common across many Schottky diodes, easing second-source substitution.
