ASSR-4110, ASSR-4111, ASSR-4120
General Purpose, Form A, Solid State Relay (Photo MOSFET)
(400V/0.12A/25)
Data Sheet
Description
The ASSR-41xx Series consists of an AlGaAs infrared
light-emitting diode (LED) input stage optically
coupled to a high-voltage output detector circuit. The
detector consists of a high-speed photovoltaic diode
array and driver circuitry to switch on/o two discrete
high voltage MOSFETs. The relay turns on (contact
closes) with a minimum input current of 3mA through
the input LED. The relay turns o (contact opens) with
an input voltage of 0.8V or less.
The single channel configurations, ASSR-4110 and
ASSR-4111, are equivalent to 1 Form A Electromechani-
cal Relays (EMR), and the dual channel con guration,
ASSR-4120, are equivalent to 2 Form A EMR. They are
available in 4-pin SO, 6-pin DIP, 8-pin DIP and Gull
Wing Surface Mount for DIP packages. Their electrical
and switching characteristics are speci ed over the
temperature range of -40°C to +85°C. They are used for
general purpose switching of signals and low power
AC/DC loads.
ASSR-4111 enables AC/DC and DC-only output
connec tions. For DC-only connection, the output
current, Io, increases to 0.24A and the on-resistance,
R(ON) reduces to 8.5.

Notes:
1. For derating, refer to Figure 1, 2, 3 and 4.
2. The voltage across the output terminals of the relay should not exceed this rated withstand voltage. Over-voltage protection circuits should
be added in some applications to protect against over-voltage transients.
3. Threshold to switch device is IF 0.5 mA, however, for quali ed device performance over temperature range, it is recommended to operate
at IF = 5 mA.
4. Device is considered as a two terminal device:
ASSR-4110 - pin 1, 2 shorted and pin 3, 4 shorted.
ASSR-4111 - pin 1, 2, 3 shorted and pin 4, 5, 6 shorted.
ASSR-4120 - pin 1, 2, 3, 4 shorted and pin 5, 6, 7, 8 shorted.
5. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if applicable), your
equipment level safety speci cation, or Avago Technologies Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
6. During the pulsed R(ON) measurement ( IO duration 30 ms), ambient (TA) and case temperature (TC) are equal.

Applications Information
On-Resistance and Derating Curves
The Output On-Resistance, R(ON), speci ed in this data
sheet, is the resistance measured across the output
contact when a pulsed current signal (Io = 120 mA) is
applied to the output pins. The use of a pulsed signal
(≤ 30 ms) implies that each junction temperature is
equal to the ambient and case temperatures. The
steady-state resistance, Rss, on the other hand, is the
value of the resistance measured across the output
contact when a DC current signal is applied to the
output pins for a duration su cient to reach thermal
equilibrium. Rss includes the e ects of the temperature
rise in the device.
Figure 2. Maximum Output Current Rating vs Ambient Temperature
(ASSR-4111-001E)
Figure 1. Maximum Output Current Rating vs Ambient Temperature
(ASSR-4110-003E)
Figure 1, 2, 3 and 4 specify the maximum average
output current allowable for a given ambient tem-
perature. The maximum allowable output current and
power dissipation are related by the expression Rss =
Po(max)/(Io(max))2 from which Rss can be calculated.
Staying within the safe area assures that the steady
state MOSFET junction temperature remains less than
125°C.
Turn On Time and Turn O Time Variation
The ASSR-41xx Series exhibits a very fast turn on and
turn o time. Both the turn on and turn o time can
be adjusted by choosing proper forward current as
depicted in Figures 11 and 13. The changes of the turn
on and turn o time with ambient temperature are also
shown in Figures 12 and 14.
