DESCRIPTION The H21A series are gallium arsenide infrared emitting diode coupled with a silicon photodarlington in a plastic housing. The packaging system is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejection, cost and reliability. The gap in the housing provides a means of interrupting the signal with an opaque material, switching the output from an “ON” to an “OFF” state. FEATURES • Opaque housing • Low cost • .035” apertures • High IC(ON) 2001 Fairchild Semiconductor Corporation DS300291 6/05/01 1 OF 4 www.fairchildsemi.com PHOTOTRANSISTOR OPTICAL INTERRUPTER SWITCH H21A4 ABSOLUTE MAXIMUM RATINGS H21A5 H21A6 (TA = 25°C unless otherwise specified) Parameter Operating Temperature Storage Temperature Soldering Temperature (Iron)(2,3 and 4) Soldering Temperature (Flow)(2 and 3) INPUT (EMITTER) Continuous Forward Current Reverse Voltage Power Dissipation (1) OUTPUT (SENSOR) Collector to Emitter Voltage Emitter to Collector Voltage Collector Current Power Dissipation (TC = 25°C)(1) Symbol TOPR TSTG TSOL-I TSOL-F Rating -55 to +100 -55 to +100 240 for 5 sec 260 for 10 sec Unit °C °C °C °C IF 50 mA VR PD 6 100 V mW VCEO 55 V VECO IC PD 4.5 20 150 V mA mW NOTE: 1.
