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 to
IEC 61000-4-2 and ISO 10605.
®
■ ECOPACK 2 compliant components
■ AEC-Q101 qualified
Complies with the following standards
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).
■ IEC 61000-4-2 level 4:
– 15 kV (air discharge)
– 8 kV (contact discharge)
■ ISO 10605, C = 330 pF, R = 330 Ω:
– 15 kV (air discharge)
– 8 kV (contact discharge)
■ ISO 7637-2 (for pulse 1 and 2a, applicable only
to parts with stand-off voltage (V ) lower than
RM
the average battery voltage: 13.5 V):
– Pulse 1: V = -100 V
S
– Pulse 2a: V = +50 V
S
– Pulse 3a: V = -150 V
S
– Pulse 3b: V = +100 V

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))
