The BAT54WS-V is a small signal Schottky diode produced by Vishay Semiconductors. It features very low turn-on voltage and fast switching. These devices are protected by a PN junction guard ring against excessive voltage, such as electrostatic discharges. The device is lead-free and complies with RoHS 2002/95/EC and WEEE 2002/96/EC standards.
The BAT54WS-V is a low‑turn‑on voltage, fast‑switching small‑signal Schottky diode packaged in a SOD323 plastic case. It is lead‑free, RoHS compliant, and offered in tape‑and‑reel options for automated assembly.
