H11AG1
DESCRIPTION
The H11AG series consists of a Gallium-Aluminum-
Arsenide IRED emitting diode coupled with a silicon
phototransistor in a dual in-line package. This device
provides the unique feature of the high current transfer
ratio at both low output voltage and low input current.
This makes it ideal for use in low power logic circuits,
telecommunications equipment and portable electronics
isolation applications.

Figure 8. CMOS Input, 3KW, Zero Voltage Switching Solid State Relay
The H11AG1’s superior performance at low input currents allows standard CMOS logic circuits to directly operate a 25A solid state relay.
Circuit operation is as follows: power switching is provided by the SC160B, 25A triac. Its gate is controlled by the C203B via the DT230H
rectifier bridge. The C203B turn-on is inhibited by the 2N4256 when line voltage is above 12V and/or the H11AG is off. False trigger and
dv/dt protection are provided by the combination of the MOV
varistor and RC snubber network.

Figure 9. Telephone Ring Detector/A.C. Line CMOS Input Isolator
The H11AG1 uses less input power than the neon bulb traditionally used to monitor telephone and line voltages. Additionally. response
time can be tailored to ignore telephone dial tap, switching transients and other undesired signals by modifying the value of C2. The high
impedance to line voltage also can simply board layout spacing requirements.
