The FM4745WA-T is a Zener diode manufactured by Rectron Semiconductor. Similar to the FM4745W, it's designed to provide stable voltage regulation and overvoltage protection. It allows current to flow in the forward direction like a standard diode, but also allows reverse current flow when the voltage reaches its specific Zener voltage. The “WA” typically indicates specific characteristics related to its surge handling or tolerance compared to a standard part. It is ideal for voltage regulation, surge protection, and clipping applications requiring a reliable and compact Zener diode.
