DESCRIPTION
The H11B815 consists of a gallium arsenide infrared
emitting diode driving a silicon Darlington phototransistor
in a 4-pin dual in-line package.
FEATURES
• Compact 4-pin package
• Current Transfer Ratio: 600% minimum (at IF = 1 mA)
• High isolation voltage between input and output (5300
VRMS)
• UL recognized (File # E90700)
