With hFE of 220-475 (B-group), 100 MHz fT, low 250 mV saturation voltage, and complementary PNP BC857BW, it is ideal for general-purpose switching, signal amplification, and driver circuits in space-constrained automotive and consumer applications.","working_principle":"The BC847BW is an NPN bipolar junction transistor (BJT) in a vertical planar structure. In active mode, current flows from collector to emitter when the base-emitter junction is forward-biased (VBE > 0.6V). The collector current is controlled by the base current multiplied by the DC current gain (hFE): IC = hFE \u00d7 IB. The B-group selection ensures tight hFE binning (220-475) for consistent circuit performance. The low VCE(sat) of 250 mV minimizes power dissipation in switching applications. The 100 MHz transition frequency (fT) indicates the frequency at which the current gain drops to unity, providing sufficient bandwidth for audio and lower-RF applications. The complementary PNP BC857BW enables push-pull and class-AB amplifier designs with matched characteristics.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>Base<\/td><td>Input<\/td><td>Base terminal (current control input)<\/td><\/tr>\n<tr><td>2<\/td><td>Emitter<\/td><td>Power<\/td><td>Emitter terminal<\/td><\/tr>\n<tr><td>3<\/td><td>Collector<\/td><td>Output<\/td><td>Collector terminal (current output)<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>General-purpose NPN switching and signal amplification<\/li>\n<li>LED, relay, and small load driver circuits<\/li>\n<li>Audio preamplifier and signal processing with complementary BC857BW<\/li>\n<li>Automotive sensor interface and sub-system control<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr>\n<tr><td>Nexperia<\/td><td>BC847AW<\/td><td>SOT-323<\/td><td>A-group, hFE 125-250<\/td><\/tr>\n<tr><td>Nexperia<\/td><td>BC847CW<\/td><td>SOT-323<\/td><td>C-group, hFE 420-800<\/td><\/tr>\n<tr><td>Nexperia<\/td><td>BC847B<\/td><td>SOT-23<\/td><td>Same die, larger SOT-23 package<\/td><\/tr>\n<tr><td>Nexperia<\/td><td>BC846BW<\/td><td>SOT-323<\/td><td>65V VCEO version<\/td><\/tr>\n<tr><td>Infineon<\/td><td>BC847BW<\/td><td>SOT-323<\/td><td>Alternative source (check availability)<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6703","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6703"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6703\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6703"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6703"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6703"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6703"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
