DESCRIPTION
The H21A1, H21A2 and H21A3 consist of a
gallium arsenide infrared emitting diode
coupled with a silicon phototransistor 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.
SCHEMATIC
FEATURES
• Opaque housing
14
• Low cost
• .035” apertures
23
• High IC(ON)
1. Derate power dissipation linearly 1.33 mW/°C above 25°C.
2. RMA flux is recommended.
3. Methanol or isopropyl alcohols are recommended as cleaning
agents.
4. Soldering iron tip 1/16” (1.6mm) minimum from housing.
