描述 Description

The SMTOAK2 TVS Diode Series is housed in a modified

SMTO-263 package , achieving a compact mechanical

design and compatible with automated PCB assembly. The

SMTOAK2 series is designed to protect sensitive electronics

against surge events and inductive load switching voltage

transient events.
