The SML4763A with Zener diodes is a surface-mount Sod-123 RoHS electronic component manufactured by Formosa. It is a dual-active, bidirectional transient voltage suppressor that can provide protection against high voltage transients such as electrostatic discharge (ESD) and electrical fast transients (EFT) in electronic circuits. It features a breakdown voltages of 6.2V, 7.0V, 8.2V, 9.1V or 12.0V, with peak power ratings up to 500W. The component is RoHS compliant and is composed of a single Zener diode in a Sod-123 package. It is suitable for use in automotive, industrial and consumer electronics applications.
