Description
.
The LDP01-xxAY Transil™ series have been
designed to protect automotive sensitive circuits
against surges defined in ISO 7637-2 and
ISO 16750 tests A and B also called load-dump.
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.
