Parametric fit for low-power Schottky switching
The BAT5406E6327HTSA1: The 5 ns reverse recovery time (trr) places it in the small-signal fast-switching class — suitable for rectification and clamping in low-current DC-DC converters, OR-ing diodes, and protection networks where the blocking voltage stays under 30 V and the forward drop matters at the operating current. Forward voltage is specified at 800 mV maximum at 100 mA — this is the conduction loss figure for the typical operating point. Reverse leakage is 2 µA at 25 V, which rises with junction temperature but stays manageable for battery-powered circuits where standby current is budgeted.
Housed in the SOT-23-3 (PG-SOT23) surface-mount package, the BAT5406E6327HTSA1 shares the standard 3-pin footprint common to small-signal diodes and transistors. The common-anode pinout ties the two anodes to pin 1, with the cathodes on pins 2 and 3 — confirm the orientation against the PCB layout before soldering. For a 200 mA load in a 25 °C ambient, the self-heating is low, but if the diode sits near a hot regulator or in a 85 °C enclosure, the derating margin narrows — the forward voltage increases with temperature, raising conduction losses.
ROHS3 compliant — no exemptions that require special handling for EU markets.
