ASSR-4110, ASSR-4111, ASSR-4120
General-Purpose, Form A, Solid State Relay
(Photo MOSFET) (400V/0.12A/25Ω)
Description
The Broadcom
®
ASSR-41xx 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 3 mA through the input LED. The
relay turns off (contact opens) with an input voltage of 0.8V
or less.
The single channel configurations, ASSR-4110 and
ASSR-4111, are equivalent to 1 Form A Electromechanical
Relays (EMR), and the dual channel configuration,
ASSR-4120, are 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. Their electrical and
switching characteristics are specified over the temperature
range of –40°C to +85°C. They are used for general
purpose switching of signals and low power AC/DC loads.
ASSR-4111 enables AC/DC and DC-only output
connections. For DC-only connection, the output current, Io,
increases to 0.24A and the on-resistance, R(ON) reduces to
8.5W.
CAUTION!
It is advised that normal static precautions be
taken in handling and assembly of this
component to prevent damage and/or
degradation which may be induced by ESD.
