ASSR-1218 , ASSR-1219 and ASSR-1228
Form A, Solid State Relay (Photo MOSFET)
(60V/0.2A/10â¦)
Data Sheet
Description
The ASSR-12XX 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 volt-
age 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 volt-
age of 0.8V or less.
The single channel configurations, ASSR-1218 and
ASSR-1219, are equivalent to 1 Form A ElectromechaniÂ
cal Relays (EMR), and the dual channel configuration,
ASSR-1228, 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. ASSR-1219 enables
AC/DC and DC-only output connections. For DC-only
connection, the output current, Io, increases to 0.4A
and the on-resistance, R(ON) reduces to 2.5â¦.
