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
APPLICATIONS / BENEFITS
Available in both Unidirectional and Bidirectional
construction (Bidirectional with C or CA suffix)
Selections for 33 to 400 volt standoff voltages VWM
Suppresses transients up to 30 kW @ 10/1000 s
and 200 kW @ 8/20 s (see Figure 1)
Fast response
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.
Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B
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 1,2,3,4: 30KP33A - 30KP400A or CA
Class 5: 30KP33A - 30KP400A or CA (short distance)
Class 5: 30KP33A - 30KP220A or CA (long distance)
Secondary lightning protection per IEC61000-4-5 with
12 Ohms source impedance:
Class 1,2, 3: 30KP33A to 30KP400A or CA
Class 4: 30KP33A to 30KP220A or CA
Secondary lightning protection per IEC61000-4-5 with
2 Ohms source impedance:
