MICROCHIP MSAC22

The MSAC5.0A through MSAC50A TVS product series are high-reliability axial-lead devices featuring a rectifier diode connected in series opposition with the primary TVS protection diode. The protected circuit sees only the rectifier diode's low capacitance of 30 pF, and RoHS-compliant versions are available. Their working peak reverse voltage VWM ranges from 5.0 to 50 volts. Multiple upscreening options are offered to enhance reliability. The low capacitance characteristics of these TVS devices make them suitable for protecting high-frequency signals and communication lines, for use in inductive switching environments or systems subject to lightning secondary effects as specified by IEC61000-4-5, and for airborne electronics compliant with RTCA/DO-160G or ARINC 429 standards. They also provide ESD and EFT protection per IEC61000-4-2 and IEC61000-4-4.
