The SMA6TY 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 this device compatible with high-end circuits where low leakage current and high junction temperature are required to provide reliability and stability over time. SMA6TY are packaged in SMA (SMA footprint in accordance with IPC 7531 standard). a.

To calculate maximum clamping voltage at another surge level, use the following formula: VCLmax = VCL - RD x (IPP - IPPappli) where IPPappli is the surge current in the application. 3. To calculate VBR or VCL versus junction temperature, use the following formulas: VBR @ TJ = VBR @ 25°C x (1 + αT x (TJ - 25)) VCL @ TJ = VCL @ 25°C x (1 + αT x (TJ - 25)) 4.
