Additional Details:

The FM4741W is typically packaged in a small surface mount package. The Zener voltage (Vz) is a critical parameter and is specified in the datasheet provided by Rectron Semiconductor. The power dissipation capability of the Zener diode is also important and must be considered in the design to prevent overheating and failure. The Zener voltage has a tolerance, which should be taken into account in applications requiring precise voltage regulation.
