FOD420, FOD4208, FOD4216, FOD4218
6-Pin DIP Triac Drivers
Features
■
300mA on-state current
■
High blocking voltage
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.

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.
