The 25ns typical reverse recovery time makes it ideal for high-frequency switching power supply output rectification and free-wheeling applications where fast recovery minimizes switching losses and reverse recovery current spikes. The 0.75V typical forward voltage at 2A reduces conduction losses for improved efficiency. The 175C maximum junction temperature provides a large thermal margin for demanding applications. The planar silicon construction ensures reliable operation and low leakage current. The SMB package offers a good balance between current handling capability and board space, with cathode indicated by a band marking.","working_principle":"The STTH1002CB-TR is a planar silicon PN junction diode optimized for ultrafast reverse recovery. During forward bias, current flows from anode to cathode with a forward voltage drop of approximately 0.75V at rated current. When the diode is reverse-biased (e.g., at MOSFET turn-on in a free-wheeling application), stored minority carriers in the drift region must be swept out before the diode blocks voltage. The ultrafast 25ns recovery time is achieved through platinum or gold doping that creates recombination centers, rapidly removing stored charge. The reverse recovery current flows briefly during this transition, contributing to switching losses in the MOSFET; the faster the recovery, the lower the losses. The soft recovery characteristic minimizes ringing and EMI generation.","pin_description":"<table><tr><th>Pin<\/th><th>Mnemonic<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>Anode<\/td><td>Positive terminal<\/td><\/tr><tr><td>2<\/td><td>Cathode<\/td><td>Negative terminal (banded)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>High-frequency flyback converter output rectification with 25ns recovery<\/li>\n<li>Free-wheeling diode across inductor in buck\/boost converters<\/li>\n<li>PFC boost diode in 100V-range power factor correction stages<\/li>\n<li>Snubber clamp diode in RCD snubber networks<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>US1M<\/td><td>onsemi<\/td><td>1000V\/1A, SMB<\/td><\/tr><tr><td>ES2B<\/td><td>Panjit<\/td><td>100V\/2A, similar<\/td><\/tr><tr><td>UF1002<\/td><td>onsemi<\/td><td>100V\/1A, DO-41<\/td><\/tr><tr><td>MURS210<\/td><td>onsemi<\/td><td>100V\/2A, SMB<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8801","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=8801"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8801\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=8801"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=8801"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=8801"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=8801"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
