Technical Specifications

The SDZ18VWA has a reverse standoff voltage of 18V, which is the maximum voltage that can be applied without causing significant conduction. It has a low clamping voltage, which limits the voltage that the protected circuit sees during a transient event. It has a fast response time, allowing it to quickly clamp transient voltages. It is available in a surface-mount package for easy integration into circuit boards. Key specifications include peak pulse power dissipation, clamping voltage, and operating temperature range, found on the datasheet. It is RoHS compliant.
