Description

General part information

SMAJ18CA-e3 Series

This SMAJ5.0-170A series of surface mount 500 W Transient Voltage Suppressors (TVSs) protects a variety of voltage-sensitive components from destruction or degradation. The package outline is similar to the DO-214AC or DO-214BA. It is also available in a unidirectional configuration or as bidirectional with a C or CA suffix part number as well as RoHS Compliant with an "e3"suffix. Their response time is virtually instantaneous. As a result, they can be used for protection from ESD or EFT per IEC61000-4-2 and IEC61000-4-4, or for inductive switching environments and induced RF protection. They can also protect from secondary lightning effects per IEC61000-4-5 and class levels defined herein. Microchip also offers numerous other TVS products to meet higher and lower power demands and special applications.
