ESD 抑制器/TVS 二极管 Hi Rel TVS
The high-reliability, Surface Mount, Transient Voltage Suppressor TVS product family includes a rectifier diode in series with and in the opposite direction to the primary TVS protection diode. 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-160D 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.
