3 Description
The MMBZ30VCL-Q1 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. This protection is key as automotive
systems require a high level of robustness and
reliability when they control safety devices.
The MMBZ30VCL-Q1 is packaged in the SOT-23,
providing two channels of robust transient protection
in one space-efficient form factor.
