DESCRIPTION
APPEARANCE
These Microsemi 30 kW Transient Voltage Suppressors (TVSs) are
designed for applications requiring protection of voltage-sensitive electronic
devices that may be damaged by harsh or severe voltage transients
including lightning per IEC61000-4-5 and class levels with various source
impedances described herein. This series is available in 33 to 400 volt
standoff voltages (VWM) in both unidirectional and bi-directional with either
5% or 10% tolerances of the Breakdown Voltage (VBR). Microsemi also
offers numerous other TVS products to meet higher or lower power
demands and special applications.
IMPORTANT:
For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES @ 250C UNLESS OTHER WISE SPECIFIED
APPLICATIONS / BENEFITS
Available in both Unidirectional and Bidirectional
construction (Bidirectional with a CA suffix)
Suppresses transients up to 30 kW @ 10/1000 s and
200 kW @ 8/20 s (see Figure 1)
Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B
Glass passivated chip junction in a P600 package
Reverse leakage below 2 A for voltages above 73
volts VBR
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 JANTX are available by adding MX prefix to
the part number.
RoHS Compliant devices available by adding “e3” suffix
