Series Schottky pair for high-speed clamping and rectification
The STMicroelectronics BAR43SFILM is a Schottky diode array with a 1 Pair Series Connection configuration, rated for 30 V DC reverse voltage and 100 mA average rectified current per diode. The 5 ns reverse recovery time makes it a fit for high-frequency switching, clamping, and protection circuits where the series pair provides a common-cathode-like topology in a single SOT-23-3 package.
Forward drop and leakage — the BOM trade-offs
Reverse leakage is specified at 500 nA at 30 V, a value that climbs with junction temperature — the 150°C maximum junction rating means the leakage current can dominate the thermal budget in a confined SOT-23-3 layout if the ambient is high.
