The 15KPA17e3 - 15KPA280CAe3 series of devices clamps dangerous high-voltage short-term transients such as those produced by the secondary effects of lightning strikes, providing circuit protection to several class levels in the IEC61000-4-5 specification. Clamping time is virtually instantaneous. It also provides protection from transients caused by inductive load dumps, induced RFI, and ESD, providing protection to IEC61000-4-2 and -4-4.
