zOutline
RSB18V is a bi-directional zener diode having two
zeners confronted in one package, aimed to absorb the
surge in plus and minus directions arising from the signal
line in mobile phone, consumer electronics such as PC,
and automotive applications.
In general, two pieces of zener diodes are used as ESD
protector to absorb the surge in +/ - directions. Paying
attention to this point and using its original technology,
ROHM succeeded to incorporate 2 zeners in one die /
package for benefit of space-saving on the circuit board.
