Bi-Directional Zener Diodes
RSB27V
Outline
RSB27V 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.

Products listed in this document are no antiradiation design.
The products listed in this document are designed to be used with ordinary electronic equipment or devices
(such as audio visual equipment, office-automation equipment, communications devices, electrical
appliances and electronic toys).
Should you intend to use these products with equipment or devices which require an extremely high level
of reliability and the malfunction of which would directly endanger human life (such as medical
instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers
and other safety devices), please be sure to consult with our sales representative in advance.
It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance
of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow
for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in
order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM
cannot be held responsible for any damages arising from the use of the products under conditions out of the
range of the specifications or due to non-compliance with the NOTES specified in this catalog.
