When current flows through the LED, it emits infrared light detected by the phototransistor base region, causing collector current proportional to the LED current (CTR). The base pin allows external biasing for gain adjustment or speed optimization.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Anode<\/td><td>LED anode (connect via resistor)<\/td><\/tr><tr><td>2<\/td><td>Cathode<\/td><td>LED cathode<\/td><\/tr><tr><td>3<\/td><td>NC<\/td><td>No connect<\/td><\/tr><tr><td>4<\/td><td>Emitter<\/td><td>Phototransistor emitter<\/td><\/tr><tr><td>5<\/td><td>Collector<\/td><td>Phototransistor collector<\/td><\/tr><tr><td>6<\/td><td>Base<\/td><td>Phototransistor base (optional bias)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>AC-DC SMPS feedback loop<\/li><li>Industrial control I\/O isolation<\/li><li>Motor drive signal isolation<\/li><li>Appliance sensor systems<\/li><li>Medical equipment isolation<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>CNY17-2<\/td><td>Various<\/td><td>CTR 63-125%<\/td><td>Higher CTR<\/td><\/tr><tr><td>4N25<\/td><td>Vishay<\/td><td>CTR 20% min<\/td><td>Same pinout<\/td><\/tr><tr><td>PC817<\/td><td>Sharp<\/td><td>CTR 50-300%<\/td><td>DIP-4 no base<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9782","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9782"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9782\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9782"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9782"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9782"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9782"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
