SMCJ45A Datasheet

SURFACE MOUNT 1500 Watt Transient Voltage Suppressor


The SMCJ5.0-170A or SMCG5.0-170A series of 1500 W Transient Voltage Suppressors (TVSs) protects a variety of voltage-sensitive components from destruction or degradation. It is available in J-bend design (SMCJ) with the DO-214AB package for greater PC board mounting density or in a Gull-wing design (SMCG) in the DO-215AB for visible solder connections. Selections include unidirectional and bidirectional. They can protect from secondary lightning effects per IEC61000-4-5 and class levels defined herein, or for inductive switching environments and induced RF protection. Since their response time is virtually instantaneous, they can also be used in protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.

• Economical surface mount design in both J-bend or Gull-wing terminations
• Available in both Unidirectional and Bidirectional construction with a C or CA suffix
• Suppresses transients up to 1500 watts @ 10/1000 µs
• Qualified to UL497B
• Optional 100% screening for avionics grade is available by adding MA prefix to part number for added 100% temperature cycle -55oC to +125oC (10X) as well as surge (3X) and 24 hours HTRB with post test VZ & IR (in the operating direction for unidirectional or both directions for bidirectional)
• Options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers.
• Axial-lead equivalent packages for thru-hole mounting available as 1.5KE6.8 to 1.5KE200CA or 1N6267 thru 1N6303A and 1N5908 (consult factory for other surface mount options)
• Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B

• Selections for 5.0 to 170 volts standoff voltages (VWM)
• Protection from switching transients and induced RF
• Protection from ESD, and EFT per IEC 61000-4-2 and IEC 61000-4-4
• Secondary lightning protection per IEC61000-4-5 with
   42 Ohms source impedance:
   Class 1: SMC 5.0 to SMC 170A or CA
   Class 2: SMC 5.0 to SMC 150A or CA
   Class 3: SMC 5.0 to SMC 75A or CA
   Class 4: SMC 5.0 to SMC 36A or CA
• Secondary lightning protection per IEC61000-4-5 with
   12 Ohms source impedance:
   Class 1 : SMC 5.0 to SMC 90A or CA
   Class 2: SMC 5.0 to SMC 45A or CA
   Class 3: SMC 5.0 to SMC 24A or CA
   Class 4: SMC 5.0 to SMC 11A or CA
• Secondary lightning protection per IEC61000-4-5 with
   2 Ohms source impedance:
   Class 2: SMC 5.0 to SMC 22A or CA
   Class 3: SMC 5.0 to SMC 10A or CA
