Description
The FOD420, FOD4208, FOD4216 and FOD4218
devices consist of an infrared emitting diode coupled to a
hybrid random phase triac formed with two inverse
parallel SCRs which form the triac function capable of
driving discrete triacs. The FOD4216 and FOD4218
utilize a high efficiency infrared emitting diode which
offers an improved trigger sensitivity. These devices are
housed in a standard 6-pin dual in-line (DIP) package.

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise noted)
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.
Note:
1. Isolation voltage, V
ISO
, is an internal device dielectric breakdown rating. For this test, Pins 1, 2 and 3 are common,
and Pins 4, 5 and 6 are common. 5,000 VRMS for 1 minute duration is equivalent to 6,000 VRMS for 1 second
duration.

Notes:
2. Test voltage must be applied within dv/dt rating.
3. All devices are guaranteed to trigger at an I
F
value less than or equal to max I
FT
. Therefore, recommended operating
I
F
lies between max I
FT
(2mA for FOD420 and FOD4208 and 1.3mA for FOD4216 and FOD4218 and the absolute
max I
F
(30mA).
4. This is static dv/dt. See Figure 11 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only.
5. Isolation voltage, V
ISO
, is an internal device dielectric breakdown rating. For this test, Pins 1, 2 and 3 are common,
and Pins 4, 5 and 6 are common.
Typical Application
Typical circuit for use when hot line switching is required.
In this circuit the “hot” side of the line is switched and the
load connected to the cold or neutral side. The load may
be connected to either the neutral or hot line.
R
in
is calculated so that I
F
is equal to the rated I
FT
of the
part, 2mA for FOD420 and FOD4208, 1.3mA for
FOD4216 and FOD4218. The 39
Ω
resistor and 0.01µF
capacitor are for snubbing of the triac and may or may
not be necessary depending upon the particular triac
and load use.

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

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.
