3 Description
The MMBZ30VCL is a dual channel unidirectional
or single channel bidirectional ESD in a common
cathode configuration. The device's low capacitance
and low leakage features enable use in high speed
applications. The low dynamic resistance allows low
clamping voltage to help protect systems against
transient events.
The MMBZ30VCL is packaged in the SOT-23,
providing two channels of robust transient protection
in one space-efficient form factor.
