The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.Uses: 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, and telecommunication. TVS components are ideal for the protection of I/O interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.Key Features?Low profile package?Ideal for automated placement?Glass passivated chip junction?Excellent clamping capability?Very fast response time?Low incremental surge resistance?Low incremental surge resistance?Typical failure mode is short from over-specified voltage or current?Low inductanceMECHANICAL DATACase: SMB (DO-214AA)Molding compound meets UL 94 V-0 flammability ratingBase P/N-E3-RoHS-compliant, commercial gradeBase P/N-M3 - halogen-free, RoHS-compliant, commercial gradeBase P/NHE3 X- RoHS-compliant and AEC-Q101 qualified Base P/NHM3 X halogen-free, RoHS-compliant, and AEC-Q101 qualified ("_X" denotes revision code e.g. A, B, ...)Terminals: matte tin plated leads, solderable per J-STD-002 and JESD 22-B102 E3, M3, HE3, and HM3 suffix meets JESD 201 class 2 whisker testPolarity: for unidirectional types the band denotes cathode end, no marking on bidirectional types
