Unidirectional Bidirectional
SMA
(JEDEC DO-214AA)
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).
Transil™ is a trademark of STMicroelectronics.
