Description
The SMA6FY Transil series are designed to protect sensitive automotive circuits
against surges defined in ISO 7637 series and against electrostatic discharges
according to ISO 10605.
The Planar technology makes it compatible with high-end circuits where low leakage
current and high junction temperature are required to provide long term reliability and
stability.
