Description
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.

1. To calculate VBR or VCL versus junction temperature, use the following formulas:
•
VBR at TJ = VBR at 25 °C x (1 + αT x (TJ - 25))
•
VCL at TJ = VCL at 25 °C x (1 + αT x (TJ-25))
2. To calculate maximum clamping voltage at other surge level, use the following formula:
•
VCLmax = VBR max + RD x IPPappli where IPPappli is the surge current in the application
3. Surge capability given for both directions for unidirectional and bidirectional types.
