1 / 4 page SURFACE MOUNT 1500 Watt Transient Voltage Suppressor Microsemi Scottsdale Division 8700 E. Thomas Rd. PO Box 1390, Scottsdale, AZ 85252 USA, (480) 941-6300, Fax: (480) 947-1503 Page 1 Copyright 2005 2-23-05 REV C SCOTTSD A L E DIVISION SMCJ5.0 thru SMCJ170CA and SMCG5.0 thru SMCG170CA DESCRIPTION APPEARANCE 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. NOTE: All SMC series are equivalent to prior SMM package identifications. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • 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 -55 oC 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 MAXIMUM RATINGS MECHANICAL AND PACKAGING • Peak Pulse Power dissipation at 25 ºC: 1500 watts at 10/1000 µs (also see Fig 1,2, and 3) • Impulse repetition rate (duty factor): 0.01% • tclamping (0 volts to V(BR) min.): < 100 ps theoretical for unidirectional and < 5 ns for bidirectional • Operating and Storage temperature: -65 ºC to +150ºC • Thermal resistance: 20 ºC/W junction to lead, or 80ºC/W junction to ambient when mounted on FR4 PC board (1oz Cu) with recommended footprint (see last page) • Steady-State Power dissipation: 6 watts at TL = 30 oC, or 1.56 watts at TA = 25 ºC when mounted on FR4 PC board with recommended footprint • Forward Surge: 200 Amps peak impulse of 8.3 ms half-sine wave at 25ºC (unidirectional only) • Solder temperatures: 260 ºC for 10 s (maximum) • CASE: Void-free transfer molded thermosetting epoxy body meeting UL94V-0 • TERMINALS: Gull-wing or C-bend (modified J-bend) leads, tin-lead plated solderable to MIL-STD-750, method 2026 • POLARITY: Cathode indicated by band.
