BAT54-V/54A-V/54C-V/54S-V is a small signal Schottky diode from Vishay Semiconductors with very low turn-on voltage and fast switching.
The BAT54 series are small‑signal Schottky diodes offered in SOT‑23 packages. They feature very low turn‑on voltage, fast switching, and protection against electrostatic discharge. The datasheet lists detailed electrical, thermal, and mechanical characteristics for each variant (BAT54‑V, BAT54A‑V, BAT54C‑V, BAT54S‑V).
Key specifications include a typical forward voltage of about 240 mV at 1 mA, a reverse breakdown voltage of 30 V, and a power dissipation rating of 230 mW. The devices are RoHS‑compliant, lead‑free, and supplied in tape‑and‑reel or bulk packaging options.
