1500 Watt Low Capacitance
Transient Voltage Suppressor
DESCRIPTION
This Transient Voltage Suppressor (TVS) product family includes a rectifier diode element in
series and in an opposite direction. This allows it to achieve low capacitance performance
below 100 pF (see
figure 2).
The low level of TVS capacitance may be used for protecting
higher frequency applications in inductive switching environments or electrical systems
involving secondary lightning effects per IEC61000-4-5 as well as RTCA/DO-160 or ARINC
429 for airborne avionics. With virtually instantaneous response, 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 in opposite directions (anti-
parallel) for complete ac protection as shown in
figure 4.
