1.0 A Output Current
FOD3150
Description
The FOD3150 is a 1.0 A Output Current Gate Drive Optocoupler,
capable of driving most 800 V / 20 A 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 ON Semiconductor patented 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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Maximum pulse width = 10 ms, maximum duty cycle = 0.2 %.
2. Derate linearly above 87°C, free air temperature at a rate of 0.77 mW/°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
