VR0402/0603
5.5 V to 15 V
electronics devices against high
voltage transient surges in the low
voltage region. They offer excellent
transient energy absorption due to
improved energy volume distribution
and power dissipation. The wide
operating voltage and energy range
make them suitable for numerous
applications on Vcc protection, I/O
protection, Keyboard protection, LCD
protection and Sensor
protection…etc..
