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.
