Data Sheet ASSR-, ASSR-, ASSR-, ASSR- (Photo MOSFET) (V/.A/.Ω) Description The ASSR-XX Series is specifically designed for high current applications, commonly found in the industrial applications. The ASSR-XX 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 ma through the input LED. The relay turns off (contact opens) with an input voltage of.v or less. The single-channel configurations, ASSR- and ASSR-, are equivalent to Form A Electromechanical Relays (EMR), and the dual-channel configuration, ASSR- and ASSR-, is equivalent to Form A EMR. They are available in -pin SO, -pin DIP, -pin DIP and Gull Wing Surface Mount for DIP packages and true surface mount SO-pin. Their electrical and switching characteristics are specified over the temperature range of C to + C. ASSR- enables AC/DC and DC-only output connections. For DC-only connection, the output current, I O, increases to A and the on-resistance, R (ON) reduces to.ω. 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.

ASSR-, ASSR-, ASSR-, ASSR- Data Sheet Applications Information On-Resistance and Derating Curves The Output On-Resistance, R (ON), specified in this data sheet, is the resistance measured across the output contact when a pulsed current signal (I O = A) is applied to the output pins. The use of a pulsed signal ( ms) implies that each junction temperature is equal to the ambient and case temperatures. The steady-state resistance, Rss, on the other hand, is the value of the resistance measured across the output contact when a DC current signal is applied to the output pins for a duration sufficient to reach thermal equilibrium. Rss includes the effects of the temperature rise in the device. Derating curves are shown in Figure, Figure, Figure, (Photo MOSFET) (V/.A/.Ω) and Figure, specifying the maximum output current allowable for a given ambient temperature. The maximum allowable output current and power dissipation are related by the expression Rss = Po(max)/(Io(max)) from which Rss can be calculated. Staying within the safe area ensures that the steady-state MOSFET junction temperature remains less than C. Turn On Time and Turn Off Time Variation The ASSR-xx Series exhibits a very fast turn on and turn off time. Both the turn on and turn off time can be adjusted by choosing proper forward current as depicted in Figure and Figure. The changes of the turn on and turn off time with ambient temperature are also shown in Figure and Figure.
