Description
Features
The ASSR-14XX 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/off 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 off (contact opens) with
an input voltage of 0.8V or less.
• Compact Solid-State Bi-directional Signal Switch
The single channel configurations, ASSR-1410 and
ASSR-1411, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual channel configuration,
ASSR-1420, is 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 specified 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.
• Low On-Resistance:
0.2 Ω Typical for DC-only,
0.7 Ω Typical for AC/DC
ASSR-1411 enables AC/DC and DC-only output connec
tions. For DC-only connection, the output current, Io,
increases to 1.2A and the on-resistance, R(ON) reduces
to 0.5W.

- 3750 Vrms for 1 min per UL1577
- CSA Component Acceptance
• Single and Dual Channel Normally-off Single-PoleSingle-Throw (SPST) Relay
• 60V Output Withstand Voltage
• 0.6A or 1.2A Current Rating
(See Schematic for ASSR-1411 Connection A and B)
• Low Input Current: CMOS Compatibility
• Very High Output Off-state Impedance:
10 Teraohms Typical
• High Speed Switching:

Note
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 ≥ 0.5mA, however, for qualified device performance over temperature range, it is recommended to operate at
IF =5mA.
4. Device is considered as a two terminal device:
ASSR-1410 - pin 1, 2 shorted and pin 3, 4 shorted.
ASSR-1411 - pin 1, 2, 3 shorted and pin 4, 5, 6 shorted.
ASSR-1420 - 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 specification, or Avago Technologies Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
6. During the pulsed R(ON) measurement ( IO duration ≤30ms), ambient (TA) and case temperature (TC) are equal.

Applications Information
On-Resistance and Derating Curves
The Output On-Resistance, R(ON), specified in this data
sheet, is the resistance measured across the output
contact when a pulsed current signal (Io=0.6A) is ap
plied to the output pins. The use of a pulsed signal (≤
30ms) 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 sufficient to reach thermal equilibrium. Rss includes the effects of the temperature rise in the device.
I F = 10mA, 4-Layer Board
Turn On Time and Turn Off Time Variation
The ASSR-14XX Series exhibits a very fast turn on and
turn off time. Both the turn on and turn off time can be
adjusted by choosing proper forward current as depicted in Figures 11 and 13. The changes of the turn on and
turn off time with ambient temperature are also shown
in Figures 12 and 14.

Derating curves are shown in Figures 1, 2, 3 and 4,
specifying the maximum output current allowable for
a given ambient temperature. 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.
