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.
