MSMCGLCE170AE3 [Microchip]

The circuit being protected sees only the rectifier diode's low 100 pF capacitance. They are available in either a DO-215AB (gull-wing) or DO-214AB (J-bend) package, and RoHS compliant versions are available. The low capacitance of these TVS devices allows them to be applied to the protection of high-frequency signal and communication lines in inductive switching environments or systems exposed to the secondary effects of lightning per IEC61000-4-5, as well as RTCA/DO-160G or ARINC 429 for airborne avionics. They also protect from ESD and EFT per IEC61000-4-2 and IEC61000-4-4. If bipolar 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.
