General Information
The Bourns® Model CD0201-T20C device provides signal and power line ESD
protection for electronic devices such as cellular phones, handheld electronics and
other portable electronic applications.
The device is available in a compact industry-standard 0201 sized chip package
(0603 metric measuring 0.6 mm x 0.3 mm). It is intended to be mounted directly onto
a printed circuit board.
The device is designed to meet IEC 61000-4-2 (ESD) protection requirements.
The combination of its small size and high ESD surge capability makes the Model
CD0201-T20C well-suited for use in protecting sensitive electronics from damage or
latch-up due to ESD in portable applications.
The Model CD0201-T20C TVS diode has a working peak voltage of 20 V.
