(60V/1.0A/0.5)
Data Sheet
Description
The ASSR-15XX Series is speci cally designed for high
current applications, commonly found in the industrial
applications.
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/o 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 o (contact opens) with
an input voltage of 0.8V or less.
The single channel configurations, ASSR-1510 and
ASSR-1511, are equivalent to 1 Form A Electromechani-
cal Relays (EMR), and the dual channel con guration,
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.
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.
