Absolute Maximum Ratings

(T

A

= 25ºC unless otherwise speciﬁed)

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.

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 VCC = 30V, VEE = Ground, TA = 25°C

unless otherwise speciﬁed.

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).

DISCLAIMER

FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE

RELIABILITY, FUNCTION, OR DESIGN. FAIRCHILD DOES NOT ASSUME ANY LIABILITY ARISING OUT OF THE APPLICATION OR USE OF ANY PRODUCT OR

CIRCUIT DESCRIBED HEREIN; NEITHER DOES IT CONVEY ANY LICENSE UNDER ITS PATENT RIGHTS, NOR THE RIGHTS OF OTHERS. THESE

WHICH COVERS THESE PRODUCTS.

LIFE SUPPORT POLICY

FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE

EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.

As used herein:

1. Life support devices or systems are devices or systems which, (a) are

intended for surgical implant into the body or (b) support or sustain life,

and (c) whose failure to perform when properly used in accordance

with instructions for use provided in the labeling, can be reasonably

expected to result in a significant injury of the user.

2. A critical component in any component of a life support, device, or

system whose failure to perform can be reasonably expected to

cause the failure of the life support device or system, or to affect its

safety or effectiveness.

ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,

under Sales Support.

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.

Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failedapplications,

and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of

counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are

listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have

full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicalandproduct information.

Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide

any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our

customers to do their part in stopping this practice by buying direct or from authorized distributors.
