Rated at 100V maximum repetitive reverse voltage and 1A average forward current, this bridge rectifier provides full-wave rectification using four internally connected silicon diodes in a Graetz bridge configuration. The low 1.0V peak forward voltage per element minimizes power dissipation and improves conversion efficiency. The HF suffix indicates halogen-free and lead-free green packaging that meets IEC 61249-2-21 and RoHS requirements. The MINI2DIP package offers a significantly smaller footprint than traditional DIP bridge rectifiers.","working_principle":"The CDBHM2100L-HF bridge rectifier converts single-phase AC input to pulsating DC output using four diodes arranged in a Graetz bridge configuration. During the positive half-cycle of the AC input, two diagonally opposite diodes conduct, allowing current to flow through the load in one direction. During the negative half-cycle, the other two diodes conduct, maintaining the same current direction through the load. This full-wave rectification doubles the ripple frequency compared to half-wave rectification, simplifying downstream filtering. Each diode in the bridge drops approximately 1.0V when conducting, resulting in a total forward voltage drop of approximately 2.0V (two diodes in series per half-cycle). The 30A peak surge current rating accommodates initial power-on capacitor charging transients.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>AC Input 1<\/td><td>Input<\/td><td>AC input connection 1<\/td><\/tr><tr><td>2<\/td><td>DC+<\/td><td>Output<\/td><td>Positive DC output<\/td><\/tr><tr><td>3<\/td><td>AC Input 2<\/td><td>Input<\/td><td>AC input connection 2<\/td><\/tr><tr><td>4<\/td><td>DC-<\/td><td>Output<\/td><td>Negative DC output (ground)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>AC-DC switching power supply input bridge rectifier<\/li><li>Offline flyback converter AC input stage<\/li><li>Home appliance and white goods power supply<\/li><li>LED lighting driver AC input rectification<\/li><li>Consumer electronics power adapter and charger<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Diodes Inc<\/td><td>ABS10<\/td><td>MBS-4<\/td><td>100V 1A bridge, similar spec<\/td><\/tr><tr><td>Comchip<\/td><td>CDBHM2100G-HF<\/td><td>MINI2DIP<\/td><td>Same device, G marking variant<\/td><\/tr><tr><td>ON Semiconductor<\/td><td>MB1S<\/td><td>MBS-4<\/td><td>100V 1A SMD bridge<\/td><\/tr><tr><td>Vishay<\/td><td>MB1S-E3\/45<\/td><td>MBS-4<\/td><td>100V 1A bridge rectifier<\/td><\/tr><tr><td>Comchip<\/td><td>CDBHM2200L-HF<\/td><td>MINI2DIP<\/td><td>200V variant, same series<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9646","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9646"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9646\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9646"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9646"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9646"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9646"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
