SMPZ3940B-E3/85A Overview

To supply this electrical device, reverse leakage current of 500nA @ 32.7V is required.There is a maximum reverse leakage current that reaches 500nA.Zener single diode is important to note that during operation, the maximum voltage - Zener (Nom) is reduced to 43V.Wdiodeh a zener current of 35mA, diode is highly flexible in terms of design.When the maximum voltage - Forward (Vf) is supplied for its operation, it reaches 1.5V @ 200mA.
