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. Please

Description
The FOD8321 is a 2.5 A output current gate drive
optocoupler, capable of driving medium-power IGBT/
MOSFETs. It is ideally suited for fast-switching driving of
power IGBT and MOSFET used in motor-control inverter
applications and high-performance power systems.
The FOD8321 utilizes Fairchild’s Optoplanar
®
coplanar
packaging technology and optimized IC design to
achieve reliable high-insulation voltage and high-noise
immunity.
It consists of an Aluminum Gallium Arsenide (AlGaAs)
Light-Emitting Diode (LED) optically coupled to an
integrated circuit with a high-speed driver for push-pull
MOSFET output stage. The device is housed in a wide
body, 5-pin, small-outline, plastic package.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
T
A
= 25ºC unless otherwise specified.
Notes:
1. Maximum pulse width = 10 µs, maximum duty cycle = 0.2%.
2.
No derating required across operating temperature range.
3.
Derate linearly from 25°C at a rate of 5.2 mW/°C
4.
Functional operation under these conditions is not implied. Permanent damage may occur if the device is subjected
to conditions outside these ratings.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.

Switching Characteristics
Apply over all recommended conditions, typical value is measured at VDD = 30V, VSS = Ground, TA = 25°C unless

Notes:
9. Propagation delay tPHL is measured from the 50% level on the falling edge of the input pulse to the 50% level of the
falling edge of the VO signal.
10. Propagation delay tPLH is measured from the 50% level on the rising edge of the input pulse to the 50% level of the
rising edge of the VO signal.
11. PWD is defined as | tPHL – tPLH | for any given device.
12. The difference between tPHL and tPLH between any two FOD8321 parts under the same operating conditions, with
equal loads.
13. 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 ensure that the output remains high (i.e., VO > 15.0 V).
14. 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 ensure that the output remains low (i.e., VO < 1.0 V).
