SMAJ20A Datasheet Transient Voltage Suppressors

Manufacturer: Vishay

Overview: www.vishay.com SMAJ5.0A thru SMAJ188CA Vishay General Semiconductor Surface-Mount TRANSZORB® Transient Voltage Suppressors Cathode SMA (DO-214AC) Anode (unidirectional) (bidirectional) LINKS TO ADDITIONAL RESOURCES 3D 3D 3D Models PRIMARY CHARACTERISTICS VBR uni-directional VBR bi-directional VWM PPPM PD IFSM TJ max. Polarity 6.40 V to 231 V 6.40 V to 231 V 5.0 V to 188 V 400 W, 300 W 3.3 W 40 A 150 °C Unidirectional, bidirectional Package SMA (DO-214AC) DEVICES FOR BIDIRECTION APPLICATIONS For bidirectional use CA suffix (e.g. SMAJ10CA). Electrical characteristics apply in both directions. TYPICAL APPLICATIONS Use in sensitive electronics protection against voltage transients induced by inductive load switching and lighting on ICs, MOSFET, signal lines of sensor units for consumer, computer, industrial, automotive, and telecommunication.

This datasheet includes multiple variants, all published together in a single manufacturer document.
