Data Sheet ASSR-1410, ASSR-1411, and ASSR-1420
General-Purpose, Form A, Solid State
Relay (Photo MOSFET) (60V/0.6A/1Ω) Description
The Broadcom® ASSR-14XX Series consists of an AlGaAs
infrared light-emitting diode (LED) input stage that is
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 highvoltage 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-1410 and ASSR1411, are equivalent to 1 Form A Electromechanical Relays
(EMR), and the dual-channel configuration, ASSR-1420, 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. 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-1411 enables AC/DC and DC-only output
connections. For DC-only connection, the output current, IO,
increases to 1.2A and the on-resistance, R(ON), reduces to
0.5Ω. …
