Description
The SM4TY Transil series has been 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
reliability and stability over time. SM4TY devices
are packaged in SMA (SMA footprint in
accordance with IPC 7531 standard).
