Using ST's SuperMESH technology, the device achieves 1.56 Ohm typical RDS(on) at VGS=10V with a low 46.5nC total gate charge, providing an excellent figure of merit for high-voltage switching applications. The device is rated for 5.8A continuous drain current at TC=25C and 3.65A at TC=100C. The 300mJ single-pulse avalanche energy rating ensures ruggedness during unclamped inductive switching events. Gate-source Zener protection provides ESD robustness. The D2PAK package enables 140W power dissipation at TC=25C with a junction-to-case thermal resistance of 0.89C\/W. The device is 100% avalanche tested and targeted for offline switch-mode power supplies, PFC boost converters, motor drive inverters, and lighting ballast applications.","working_principle":"The STB6NK90ZT4 uses ST's SuperMESH vertical DMOS technology for high-voltage power switching. (1) Cell Structure: The SuperMESH process uses a striped cell geometry with optimized pitch to minimize the specific on-resistance (RDS(on) x Area). The vertical current flow from drain (substrate) through the drift region and channel to the source provides high blocking voltage and low conduction loss. (2) Drift Region: The 900V blocking capability is achieved through a lightly-doped epitaxial drift layer. The drift layer thickness and doping are optimized to support the electric field during off-state while minimizing resistance during on-state. (3) Gate Charge: The 46.5nC total gate charge includes Qgs (8.5nC) for channel inversion and Qgd (25nC) for Miller plateau. The low Qgd minimizes switching losses in hard-switched applications. (4) Avalanche: When the drain voltage exceeds V(BR)DSS, the device enters avalanche breakdown. The 300mJ energy rating ensures the device can absorb inductive kickback energy without failure. (5) Zener Protection: Integrated gate-source Zener diodes clamp gate voltage transients to +\/-20V, protecting the thin gate oxide from ESD damage.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Gate<\/td><td>Input<\/td><td>MOSFET gate (Zener protected)<\/td><\/tr><tr><td>2<\/td><td>Drain<\/td><td>Output<\/td><td>MOSFET drain (tab\/heat sink)<\/td><\/tr><tr><td>3<\/td><td>Source<\/td><td>Output<\/td><td>MOSFET source<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Offline SMPS primary switch at 900V with 1.56Ohm RDS(on)<\/li><li>PFC boost converters in CCM\/CRM with 300mJ avalanche rating<\/li><li>Motor drive inverters for industrial applications with Zener gate protection<\/li><li>Lighting ballast and LED driver converters at 5.8A continuous current<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>ST<\/td><td>STP6NK90Z<\/td><td>TO-220<\/td><td>Through-hole version<\/td><\/tr><tr><td>Infineon<\/td><td>IPD60R900P7S<\/td><td>D2PAK<\/td><td>900V, 0.9Ohm, CoolMOS<\/td><\/tr><tr><td>onsemi<\/td><td>FCPF099N65S3<\/td><td>D2PAK<\/td><td>650V SuperFET, lower voltage<\/td><\/tr><tr><td>ST<\/td><td>STW11NM80<\/td><td>TO-247<\/td><td>800V, higher power<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7174","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=7174"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7174\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7174"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7174"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7174"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7174"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
