MASMBJ78AE3 [Microchip]

This SMBJ5.0-170A series of surface mount 600 W Transient Voltage Suppressors (TVSs) protects a variety of voltage-sensitive components from destruction or degradation. It is available in J-bend design (SMBJ) with the DO-214AA package for greater PC board mounting density or in a Gull-wing design (SMBG) in the DO-215AA for visible solder connections. It is also available in both unidirectional and bidirectional configurations 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.

• Available in both unidirectional and bidirectional construction (add C or CA suffix for bidirectional)
• Selections for 5.0 to 170 volts standoff voltages (VWM)
• Optional 100% screening for avionics grade is available by adding MA prefix to part number for 100% temperature cycle -55o C to +125o C (10X) as well as surge (3X) and 24 hours HTRB with post test VZ & IR (in operating direction for unidirectional or both directions for bidirectional)
• Options for screening in accordance with MIL-PRF-19500 for JANTX are available by adding MX prefix to the part number.
• Axial-lead equivalent packages for thru-hole mounting available as P6KE6.8 to P6KE200CA (consult factory for other surface mount options)
• Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B
• RoHS compliant devices available by adding an “e3” suffix
