The resulting photocurrent acts as base current, amplified by the transistor current gain (hFE) to produce a larger collector current. The 980nm peak wavelength matches common IR emitters for optimal coupling.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Anode\/Collector<\/td><td>Collector terminal (marked with dot)<\/td><\/tr><tr><td>2<\/td><td>Cathode\/Emitter<\/td><td>Emitter terminal<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Industrial factory automation<\/li><li>Access control and security systems<\/li><li>Mobile and wearable optical sensing<\/li><li>Appliance optical interrupt detection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>BPW34<\/td><td>Vishay<\/td><td>Si PIN photodiode<\/td><td>SMD<\/td><\/tr><tr><td>TEMD6200X01<\/td><td>Vishay<\/td><td>Si phototransistor<\/td><td>SMD<\/td><\/tr><tr><td>SFH203PA<\/td><td>ams OSRAM<\/td><td>Si photodiode<\/td><td>SMD<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9840","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=9840"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9840\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9840"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9840"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9840"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9840"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
