production data
Description
A
The SM30TY Transil series has been designed to
protect automotive sensitive circuits against
surges defined in ISO 7637-2 and against
electrostatic discharges according to ISO 10605.
K
Unidirectional
Bidirectional
SMC
(JEDEC DO-214AB)
The planar technology makes it compatible with
high-end circuits where low leakage current and
high junction temperature are required to provide
reliability and stability over time. SM30TY are
packaged in SMC (SMC footprint in accordance
with IPC 7531 standard).
