With a 200 V repetitive peak reverse voltage and 16 A average forward current per device, it features very low forward voltage drop (0.78 V typical at 5A, 150\u00b0C) and fast reverse recovery (20 ns typical). The 175\u00b0C maximum junction temperature enables operation in demanding thermal environments. Packaged in a space-saving TO-252 (DPAK) surface mount package, it is designed for low voltage, high frequency inverter and free-wheeling applications.","working_principle":"The STTH1002CB-TR operates as a dual ultrafast rectifier diode with common cathode configuration. Each diode independently conducts forward current when the anode voltage exceeds the cathode voltage by the forward voltage drop (VF). During reverse recovery, the stored minority carriers are swept out rapidly, achieving a typical recovery time of 20 ns, which minimizes switching losses in high-frequency applications. The common cathode configuration allows both diodes to share the cathode connection, simplifying PCB layout in full-wave rectification or freewheeling circuits. The ultrafast recovery characteristic is achieved through optimized doping profiles and platinum or gold diffusion lifetime control.","pin_description":"<table><tr><th>Pin<\/th><th>Mnemonic<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>A1<\/td><td>Anode of diode 1<\/td><\/tr><tr><td>2<\/td><td>A2<\/td><td>Anode of diode 2<\/td><\/tr><tr><td>3<\/td><td>K1\/K2<\/td><td>Common cathode (tab)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Freewheeling diode in buck\/boost converter output stages<\/li><li>Secondary side rectification in isolated DC-DC converters<\/li>\n<li>High-frequency inverter snubber and clamp circuits<\/li>\n<li>Polarity protection in automotive and industrial power supplies<\/li>\n<li>OR-ing diode in redundant power supply configurations<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>STTH102CB-TR<\/td><td>ST<\/td><td>Single diode version<\/td><\/tr><tr><td>MURB1620CT<\/td><td>onsemi<\/td><td>Similar dual ultrafast, 16A\/200V<\/td><\/tr><tr><td>FUF1620CD<\/td><td>Vishay<\/td><td>Similar dual ultrafast diode<\/td><\/tr><tr><td>STTH2002CB-TR<\/td><td>ST<\/td><td>Higher current version<\/td><\/tr><tr><td>MBRF20100CT<\/td><td>onsemi<\/td><td>Higher voltage (100V) alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/8707","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=8707"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/8707\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=8707"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=8707"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=8707"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=8707"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
