Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

FOD3150A — High Noise Immunity, 2.5 A Output Current, Gate Drive Optocoupler
August 2013
FOD3150A
High Noise Immunity, 2.5 A Output Current,
Gate Drive Optocoupler
Features
■
High noise immunity characterized by 20 kV/µs
■
■
■
Description
The FOD3150A is a 2.5 A Output Current Gate Drive
Optocoupler, capable of driving most 800 V / 20 A
IGBTs or MOSFETs. It is ideally suited for fast switching
driving of power IGBTs and MOSFETs used in motor
control inverter applications, and high performance
power system.
It utilizes Fairchild’s 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.
