SMAJ78C-e3数据手册Microchip中文资料规格书

描述 Description

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.

特性 Features

This device has the ability to clamp dangerous high voltage, short term transients such as produced by directed orradiated electrostatic discharge phenomena before entering sensitive component regions of a circuit design. Responsetime of clamping action is virtually instantaneous. As a result, they may also be used effectively for protection fromESD or EFT per IEC61000-4-2 and IEC61000-4-4 or for inductive switching environments and induced RF. They canalso be used for protecting other sensitive components from secondary lightning effects per IEC61000-4-5 and classlevels defined herein. Microchip also offers numerous other TVS products to meet higher and lower power demandsand special applications.
• RoHS compliant (2002/95/EC), MSL level 1 (J-STD-020)
• Qualified to automotive grade – AEC Q101
• Bi-directional devices are denoted by the suffixes C or CA, electrical characteristics apply in both directions
