3 Description
The TVS3300 is a transient voltage suppressor which
provides robust protection for electronic circuits
exposed to high transient voltage events. Unlike a
traditional TVS diode, the TVS3300 precision clamp
triggers at a lower breakdown voltage and regulates
to maintain a flat clamping voltage throughout a
transient overvoltage event. The lower clamping
voltage combined with a low dynamic resistance
enables a unique TVS protection solution that can
lower the voltage a system is exposed during a surge
event by up to 30% in unidirectional configuration and
up to 20% in bidirectional configuration when
compared to traditional TVS diodes. The low
clamping voltage and flat clamping performance allow
designers to confidently select downstream system
components with maximum voltage rating than is
possible with traditional TVS diodes, saving system
cost, board area and improving overall performance.
The TVS3300 is a unidirectional precision surge
protection clamp with a 33-V working voltage
designed specifically to protect systems with mid-
voltage rails in industrial, communication, and factory
automation applications. The TVS3300 has a fast
response time when surge current is applied so there
is no overshoot voltage during clamping, making it
ideal to replace traditional TVS and zener diodes.
The TVS3300 is available in two small footprint
packages which, when used in place of an industry
standard SMB package, can reduce footprint by 94%
(WCSP package) and 79% (QFN) for space
constrained applications. Both package options
robustly dissipate the surge power and provide up to
58% lower leakage current compared to traditional
TVS diodes in SMA and SMB package, allowing for
higher accuracy 4-20-mA current loop
measurements.
