DESCRIPTION
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.
FEATURES
• 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 µs
and 200 kW @ 8/20 µs (see Figure 1)
• Fast response
• 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
