LCE6.5 – LCE170A

Available

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.
