Description
Features
The ASSR-40xC Series is specifically designed for fast
switching applications, commonly found in the test and
measurement systems. The low C x R and low output offstate leakage current provide higher system throughput
and reduce system errors.
• Compact Solid-State Bi-directional Signal Switch
• Single and Dual Channel Normally-off Single-PoleSingle-Throw (SPST) Relay
• 400V Output Withstand Voltage
• 0.04A Current Rating
• Low Input Current: IF = 1mA
• Low C x R: 650pF•Ω typical
• Low Output Off-state Leakage Current: 0.3nA typical
• Fast Speed Switching: 0.08ms (Ton), 0.05ms (Toff )
typical
• High Transient Immunity: >1kV/ms
• High Input-to-Output Insulation Voltage
(Safety and Regulatory Approvals Pending)
- 3750 Vrms for 1 min per UL1577
- CSA Component Acceptance
The dual channel configuration of ASSR-402C is equivalent to 2 Form A Electromechanical Relays (EMR). One
channel of the relay 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 1mA through the input LED.
The relay turns off (contact opens) with an input voltage
of 0.8V or less.
ASSR-401C is available in 4-pin SO package and ASSR402C is available in 8-pin DIP and Gull Wing Surface
Mount packages. Their electrical and switching characteristics are specified over the temperature range of
-40°C to +85°C.

Note
Notes:
1. For qualified device performance over temperature range, it is recommended to operate at IF =5mA.
2. Device is considered as a two terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7 and 8 shorted together.
3. 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.”
4. The PCB design and environmental conditions are taken into consideration when measuring the IO(OFF) performance.
5. During the pulsed R(ON) measurement ( IO duration ≤30ms), ambient (TA) and case temperature (TC) are equal.
