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 (SMA
footprint in accordance with IPC 7531 standard).
Complies with the following standards

ISO 10605, C = 150 pF, R = 330
Ω:
– 30 kV (air discharge)
– 30 kV (contact discharge)
ISO 10605, C = 330 pF, R = 330
Ω:
– 30 kV (air discharge)
– 30 kV (contact discharge)
