bidirectional

3 Description

The MMBZxxVCL is a dual channel unidirectional

or single channel bidirectional ESD in 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 MMBZxxVCL is packaged in the SOT-23,

providing two channels of robust transient protection

in one space-efficient form factor.
