Description
The SM6TY series are designed to protect sensitive automotive circuits against
surges defined in ISO 7637-2 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.
