MALCE15A [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 (see Figure 6-1). They feature working standoff voltages V_WM from 6.5 to 170 volts and are available in RoHS compliant versions. 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. They also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4. Features: High reliability controlled devices with wafer fabrication and assembly lot traceability for all M prefix devices; All devices are 100% surge tested; Unidirectional low capacitance device (< 100 pF); Suppresses transients up to 1,500 watts at 10/1000 μs; 3σ lot norm screening performed on standby current I_D; Enhanced reliability screening in reference to MIL-PRF-19500 are available; Moisture classification is level 1 with no dry pack required per IPC/JEDEC J-STD-020F for all M prefix devices; RoHS compliant versions available
