DESCRIPTION

This high-reliability plastic encapsulated Transient Voltage Suppressor (TVS) diode series for thru-hole

mounting includes a rectifier diode element in series and in the opposite direction. This allows it to

present a very low (< 100 pF) capacitance to the system it is protecting (see Figure 2). The low

capacitance of these devices makes them particularly useful for protecting lines carrying high frequency

signals. They are also useful in protecting from the secondary effects of lightning in airborne avionics per

IEC61000-4-5, RTCA/DO-160G, and ARINC 429. If bidirectional 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.
