ASSR-1218 - Solid State Relay

Datasheet Summary

Description

The Broadcom® ASSR-12XX Series consists of an AlGaAs infrared light-emitting diode (LED) input stage that is optically coupled to a high-voltage output detector circuit.

Features

  • Compact solid-state bidirectional signal switch.
  • Single and dual-channel normally-off Single-Pole- Single-Throw (SPST) relay.
  • 60V output withstand voltage.
  • 0.2A or 0.4A current rating.
  • See schematics for ASSR-1219 Connection A and Connection B.
  • Low input current: CMOS compatibility.
  • Low On-Resistance.
  • 0.25Ω typical for DC-only.
  • 1Ω typical for AC/DC.

ASSR-1218, ASSR-1219, and ASSR-1228 Form A, Solid State Relay (Photo MOSFET) (60V/0.2A/10Ω) Data Sheet Description The Broadcom® ASSR-12XX 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 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-1218 and ASSR-1219, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual-channel configuration, ASSR-1228, is equivalent to 2 Form A EMR.
