MALCE54AE3 [Microchip]

This series of high-reliability plastic encapsulated TVS diodes is designed for thru-hole mounting and features a rectifier diode element in series and opposite direction, providing very low capacitance (<100 pF). They offer working standoff voltages from 6.5V to 170V and are available in RoHS compliant versions. The low capacitance makes them ideal for protecting high-frequency signal lines and for secondary lightning protection in airborne avionics per IEC61000-4-5, RTCA/DO-160G, and ARINC 429. Key features include 100% surge testing, unidirectional low-capacitance operation, suppression of transients up to 1,500 watts at 10/1000 μs, enhanced reliability screening, and moisture classification level 1. They are also available in SMCG & SMCJ surface mount packages.
