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.

Transil™ is a trademark of STMicroelectronics.

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.
