MLCE6.5 – MLCE170A
Available
1500 Watt Low Capacitance
Transient Voltage Suppressor
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.
