Introduction

The ASSR-41xx series consists of an AlGaAs infrared LED input stage optically coupled to a high-voltage output detector circuit. The detector includes a high-speed photovoltaic diode array and drive circuit for switching two discrete high-voltage MOSFETs. The relay turns on (contacts close) when the input LED current reaches a minimum of 3 mA. The relay turns off (contacts open) when the input voltage is 0.8V or lower. The single-channel ASSR-4110 and ASSR-4111 are equivalent to 1 Form A electromechanical relay, while the dual-channel ASSR-4120 is equivalent to 2 Form A electromechanical relays. They are available in 4-pin SO, 6-pin DIP, 8-pin DIP, and gull-wing surface-mount DIP packages. Their electrical and switching characteristics are specified over a temperature range of -40℃ to +85℃. They are designed for general-purpose switching of signal and low-power AC/DC loads. The ASSR-4111 supports both AC/DC and DC-only output connections. For DC-only connections, the output current Io increases to 0.24A and the on-resistance R(ON) decreases to 8.5Ω.
