ASSR-1611
High Current, 1 Form A, Solid State Relay (MOSFET)
(60V/2.5A/0.1)
Data Sheet
Description
Features
The ASSR-1611 is specifically designed for high current Compact Solid-State Bi-directional Signal Switch
applications, commonly found in the industrial equip-
ments. The relay is a solid-state replacement for single-
pole, normally-open, (1 Form A) electromechanical relays.
Single Channel Normally-off Single-Pole-Single-Throw
(SPST) Relay
60V Output Withstand Voltage
The ASSR-1611 consists of an AlGaAs infrared light-emit-
2.5A or 5A Current Rating
ting diode (LED) input stage optically coupled to a high-
Low Input Current: CMOS Compatibility
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 cur-
rent of 5mA through the input LED. The relay turns off
(contact opens) with an input voltage of 0.8V or less.
Low On-Resistance: 20mΩ Typical for DC-only, 65mΩ
Typical for AC/DC
High Speed Switching: 3.2ms (T ), 0.1ms (T ) Typical

High Transient Immunity: >1kV/μs
High Input-to-Output Insulation Voltage
The ASSR-1611 connection A, as shown in the schematic,
allows the relay to switch either ac or dc loads. The con-
nection B, with its advantages of reduced on-resistance
and higher output current, allows the relays to switch dc
loads only.
