Main product characteristics
Description and applications
This device has the ability to clamp dangerous high voltage, short term transients such as produced by directed or
radiated electrostatic discharge phenomena before entering sensitive component regions of a circuit design. Response
time of clamping action is virtually instantaneous. As a result, they may also be used effectively for protection from
ESD or EFT per IEC61000-4-2 and IEC61000-4-4 or for inductive switching environments and induced RF. They can
also be used for protecting other sensitive components from secondary lightning effects per IEC61000-4-5 and class
levels defined herein. Microsemi also offers numerous other TVS products to meet higher and lower power demands
and 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.
