Product overview
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).
