zOutline

RSB18F2 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.

zFeatures

1) Absorption of plus & minus surge with one package.

2) Decrease of components and space-saving on the

circuit board.
