Dual Schottky in a SOT-323 — what the 100 ps trr buys you
The Infineon BAS4006WE6327 is a dual Schottky diode with a common-anode configuration in a SOT-323 package. Each diode handles 120 mA DC average rectified current and blocks 40 V reverse voltage. The 100 ps reverse recovery time is the spec that matters for high-speed clamping and low-loss rectification in switching supplies up to a few hundred MHz. The common-anode pair is handy for steering or OR-ing two signal paths to a single rail.
40 V reverse, 1 µA leakage — the guard-band numbers
Reverse leakage is specified at 1 µA at 30 V, which gives some headroom before the 40 V absolute maximum. Forward voltage drops 1 V at 40 mA, typical for a small-signal Schottky. The junction temperature rating goes to 150°C max, so the part can sit near a hot regulator or inductor without derating the current.
Active status and sourcing posture
Infineon lists the BAS4006WE6327 as Active in its product portfolio, so there is no end-of-life or last-time-buy pressure. For buyers looking to dual-source, the BAS40-06WE6327 is a near-identical sibling — same Schottky type, same 40 V, same SOT-323 footprint — and can be qualified as a drop-in second source.
