Description
Features
The ASSR-15XX Series is specifically designed for high
current applications, commonly found in the industrial
applications.
Compact Solid-State Bi-directional Signal Switch
Single and Dual Channel Normally-off Single-Pole-
Single-Throw (SPST) Relay
The ASSR-15XX 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.
60V Output Withstand Voltage
1.0A or 2.0A Current Rating
(See Schematic for ASSR-1511 Connections A & B)
Low Input Current: CMOS Compatibility
Low On-Resistance:
0.12 Typical for DC-only, 0.35 Typical for AC/DC
Very High Output Off-state Impedance:
The single channel configurations, ASSR-1510 and
ASSR-1511, are equivalent to 1 Form A Electromechani-
cal Relays (EMR), and the dual channel configuration,
ASSR-1520 and ASSR-1530, 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 and true
surface mount SO-8pin. Their electrical and switching
characteristics are specified over the temperature
range of -40°C to +85°C.
10 Teraohms Typical
High Speed Switching: 0.25ms (Ton), 0.02ms (Toff)
Typical
High Transient Immunity: >1kV/s
High Input-to-Output Insulation Voltage
(Safety and Regulatory Approvals)
- 3750 Vrms for 1 min per UL1577
- CSA Component Acceptance
ASSR-1511 enables AC/DC and DC-only output connec-
tions. For DC-only connection, the output current, Io,
increases to 2A and the on-resistance, R(ON) reduces to
0.2.
