SMBJ20A电路保护的TVS-二极管规格书PDF中文资料

DESCRIPTION

This SMBJ5.0-170A or SMBG5.0-170A 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. Microsemi also offers numerous other TVS products to meet higher and lower power demands and special applications.

FEATURES

• 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 -55oC to +125oC (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
