NTE3097
Optoisolator
Zero Crossing TRIAC Driver
Description:
The NTE3097 is an optoisolator in a 6Lead DIP type package and contains a gallium arsenide IRED
optically coupled to a monolithic silicon detector performing the function of a Zero Voltage Crossing
bilateral TRIAC Driver. This device is designed for use with a TRIAC in the interface of logic systems
to equipment powered from 240VAC lines such as solidstate relays, industrial controls, motors, sole-
noids, and consumer appliances, etc.

Note 1. Isolation surge voltage is an internal dielectric breakdown rating. For this test, Pin1 and Pin2
are common, and Pin4, Pin5, and Pin6 are common.

Note 2. Test voltage must be applied within dv/dt rating.
Note 3. This device is guaranteed to trigger at an I
F1
value less than or equal to max. I
FT
. Therefore,
recommended operating I
F
lies between max. I
FT
(15mA) and absolute max. I
F
(60mA).
Note 4. This is static dv/dt. Commutating dv/dt is a function of the loaddriving thyristor only.
