Description
The FODM305X series consists of a galium arsenide diode
driving a silicon bilateral switch housed in a compact 4-pin mini-
flat package. The lead pitch is 2.54 mm. The FODM305X series
isolates low voltage logic from 115 and 240 Vac lines to provide
random phase control of high current triacs or thyristors. It also
features greatly enhanced static dv/dt capability to ensure
stable switching performance of inductive loads.

Note
1. Test voltage must be applied within dv/dt rating.
2. This is static dv/dt. See Figure 1 for test circuit. Commutating dv/dt is function of the load-driving thyristor(s) only.
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
(15 mA for FODM3051, 10 mA for FODM3052, 5 mA for FODM3053) and absolute max I
F
(60 mA).

SCOPE
PROBE
1. The mercury wetted relay provides a high speed
repeated pulse to the D.U.T.
2. 100x scope probes are used, to allow high speeds
and voltages.
3. The worst-case condition for static dv/dt is estab-
lished by triggering the D.U.T. with a normal LED
input current, then removing the current. The vari-
able R
TEST
allows the dv/dt to be gradually
increased until the D.U.T. continues to trigger in
response to the applied voltage pulse, even after
the LED current has been removed. The dv/dt is
then decreased until the D.U.T. stops triggering.
