DESCRIPTION

SMBJ surface mount package is utilized where power and space is a requirement.

Designed for effective protection of power bus lines from voltage spikes originating

from ESD, line noise (EFT), and induced lighting defined by IEC 1000-4-2, 1000-

4-4, and 1000-4-5 respectively. Advanced technology provides lowest clamping

voltage with surface mount packaging minimizing parasitic inductance.
