PHOTOTRANSISTOR OPTOCOUPLERS H11AG1 H11AG2 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. FEATURES • High efficiency low degradation liquid epitaxial IRED • Logic level compatible, input and output currents, with CMOS and LS/TTL • High DC current transfer ratio at low input currents • Underwriters Laboratory (UL) recognized File #E90700 APPLICATIONS • CMOS driven solid state reliability • Telephone ring detector • Digital logic isolation 6 6 1 1 6 ABSOLUTE MAXIMUM RATINGS Parameters TOTAL DEVICE Storage Temperature Operating Temperature Lead Solder Temperature Total Device Power Dissipation @ 25°C (LED plus detector) Derate Linearly From 25°C EMITTER Continuous Forward Current Reverse Voltage Forward Current - Peak (1 µs pulse, 300 pps) LED Power Dissipation 25°C Ambient Derate Linearly From 25°C DETECTOR Detector Power Dissipation @ 25°C Derate Linearly from 25°C Continuous Collector Current Symbol TSTG TOPR TSOL PD IF VR IF(pk) PD PD Device All All All All All All All All All All H11AG3 SCHEMATIC 1 ANODE 1 6 BASE CATHODE 2 5 COL N/C 3 4 EMITTER Value -55 to +150 -55 to +100 260 for 10 sec 260 3.5 50 6 3.0 75 1.0 150 2.0 50 Units °C °C °C mW mW/°C mA V A mW mW/°C mW mW/°C mA  2001 Fairchild Semiconductor Corporation DS300213 1/28/02 1 OF 8 www.fairchildsemi.com 1 page PHOTOTRANSISTOR OPTOCOUPLERS H11AG1 H11AG2 H11AG3 47Ω ≤ 25A LOAD +5V 15K H11AG1 CMOS CONTROL ≥ 0.16mA 1.5MΩ 75KΩ 47Ω SC160B 22K 2N4256 150pF C203D DT230H (4) 0.1 V130LA20A 120V 60Hz SUPPLY 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.

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. DS300213 1/28/02 5 OF 8 www.fairchildsemi.com 5 Page
