Description
Features
The ASSR-5211 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
• 600V Output Withstand Voltage
The ASSR-5211 consists of an AlGaAs infrared light-
• 0.2A or 0.4A Current Rating
emitting diode (LED) input stage optically coupled to
• Low Input Current: CMOS Compatibility
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.
• Low On-Resistance:
2.5Ω Typical for DC-only, 10Ω Typical for AC/DC
• High Speed Switching:
0.7ms (Ton), 0.07ms (Toff) Typical @ I = 5mA
F
• High Transient Immunity: >1kV/μs
• High Input-to-Output Insulation Voltage
The ASSR-5211 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.
