MLCE14AE3 [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, presenting a very low <100 pF capacitance. It features working standoff voltages V_WM from 6.5 to 170 volts and is available in RoHS compliant versions. The low capacitance makes them particularly useful for protecting lines carrying high frequency signals and for protecting from the secondary effects of lightning in airborne avionics per IEC61000-4-5, RTCA/DO-160G, and ARINC 429. Bidirectional transient capability can be achieved by using two devices in anti-parallel. They also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4.
