Automotive 3000 W TVS in SMC package

The SM30TY Transil series has been designed to protect automotive sensitive 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. SM30TY are packaged in SMC (SMC footprint in accordance with IPC 7531 standard).
