Description
The SM6TY Transil series has been designed to
protect sensitive automotive circuits against
surges defined in ISO 7637-2 and against
electrostatic discharges according ISO 10605.
■ AEC-Q101 qualified
Complies with the following standards
■ ISO 10605, C = 150 pF, R = 330 Ω:
– 30 kV (air discharge)
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. SM6TY are packaged in SMB (SMB
footprint in accordance with IPC 7531 standard).
– 30 kV (contact discharge)
■ ISO 10605, C = 330 pF, R = 330 Ω:
– 30 kV (air discharge)
– 30 kV (contact discharge)

1. Pulse test: tp < 50 ms
2. 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:
V
BR @ TJ = VBR @ 25°C x (1 + αT x (TJ - 25))
VCL @ TJ = VCL @ 25°C x (1 + αT x (TJ - 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
