Description

The SM4TY 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. SM4TY devices are packaged in SMA (SMA footprint in accordance with

IPC 7531 standard).
