DESCRIPTION APPEARANCE
This surface mount Transient Voltage Suppressor (TVS) product family includes a
rectifier diode element in series and opposite direction to achieve low capacitance
below 100 pF. They are also available as RoHS Compliant with an e3 suffix. The low
TVS capacitance may be used for protecting higher frequency applications in inductive
switching environments or electrical systemsinvolving secondary lightning effects per
IEC61000-4-5 as well as RTCA/DO-160D or ARINC 429 for airborne avionics. They
also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4. If bipolar
transient capability is required, two of these low capacitance TVS devices may be used
in parallel and opposite directions (anti-parallel) for complete ac protection (Figure 6).
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES APPLICATIONS / BENEFITS
Available in standoff voltage range of 6.5 to 200 V
Low capacitance of 100 pF or less
Molding compound flammability rating: UL94V-O
Two different terminations available in C-bend (modified J-
Bend with DO-214AB) or Gull-wing (DO-215AB)
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
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 VBR & IR
RoHS Compliant devices available by adding an “e3” suffix

NOTE 1: TVS are normally selected according to the reverse “Stand Off Voltage” (VWM) which should be equal to or greater than the dc or continuous
peak operating voltage level.

SCHEMATIC APPLICATIONS
The TVS low capacitance device configuration is shown in Figure 4. As a further option for unidirectional applications, an additional low
capacitance rectifier diode may be used in parallel in the same polarity direction as the TVS as shown in Figure 5. In applications where random
high voltage transients occur, this will prevent reverse transients from damaging the internal low capacitance rectifier diode and also provide a
low voltage conducting direction. The added rectifier diode should be of similar low capacitance and also have a higher reverse voltage rating
than the TVS clamping voltage VC. The Microsemi recommended rectifier part number for the application in Figure 5 is the “SMBJLCR80” or
“SMBGLCR80” depending on the terminal configuration desired. If using two (2) low capacitance TVS devices in anti-parallel for bidirectional
applications, this added protective feature for both directions (including the reverse of each rectifier diode) is inherently provided in Figure 6. The
unidirectional and bidirectional configurations in Figure 5 and 6 will both result in twice the capacitance of Figure 4.
