Description
The FOD3120 is a 2.5A Output Current Gate Drive
Optocoupler, capable of driving most 1200V/20A
IGBT/MOSFET. It is ideally suited for fast switching
driving of power IGBT and MOSFETs used in motor
control inverter applications, and high performance
power system.
It utilizes Fairchild’s proprietary coplanar packaging
technology, Optoplanar®, and optimized IC design to
achieve high noise immunity, characterized by high
common mode rejection.
It consists of a gallium aluminum arsenide (AlGaAs) light
emitting diode optically coupled to an integrated circuit
with a high-speed driver for push-pull MOSFET output
stage.

Notes:
1. Maximum pulse width = 10µs, maximum duty cycle = 1.1%
2. Derate linearly above 87°C, free air temperature at a rate of 0.77mW/°C
3. No derating required across temperature range.
4. Functional operation under these conditions is not implied. Permanent damage may occur if the device is
subjected to conditions outside these ratings.
5. Device is considered a two terminal device: Pins 2 and 3 are shorted together and Pins 5, 6, 7 and 8 are shorted
together.
6. 5,000 VRMS for 1 minute duration is equivalent to 6,000 VACRMS for 1 second duration.
7. The difference between tPHL and tPLH between any two FOD3120 parts under same test conditions.
8. Common mode transient immunity at output high is the maximum tolerable negative dVcm/dt on the trailing edge of
the common mode impulse signal, Vcm, to assure that the output will remain high (i.e. VO > 15.0V).
9. Common mode transient immunity at output low is the maximum tolerable positive dVcm/dt on the leading edge of
the common pulse signal, Vcm, to assure that the output will remain low (i.e. VO < 1.0V).
