MXLLCE30A [Microchip]

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. They feature working standoff voltages V_WM from 6.5 to 170 volts and are available in RoHS compliant versions. The low capacitance makes them particularly useful for protecting lines carrying high frequency signals. They also protect from secondary effects of lightning in airborne avionics per IEC61000-4-5, RTCA/DO-160G, and ARINC 429. For bidirectional capability, two devices may be used in parallel and opposite directions. They also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
