It is RoHS3 compliant.","metaTitle":"STD2NK90ZT4 MOSFET N-CH 900V 2.1A DPAK, Active","metaDescription":"STD2NK90ZT4 N-channel 900V 2.1A MOSFET in DPAK. SuperMESH™ series, 6.5 Ohm Rds(on) at 10V.

The moderate gate charge and capacitance keep switching losses low at frequencies up to ~100 kHz with an appropriate gate driver."},{"question":"What is the difference between STD2NK90ZT4 and STP2NK90Z?","answer":"The primary difference is package: STD2NK90ZT4 is surface-mount DPAK (TO-252), while STP2NK90Z is through-hole TO-220. Electrical ratings are similar — both are 900 V, 2.1 A N-channel SuperMESH™ MOSFETs. The DPAK version suits automated assembly and space-constrained boards; the TO-220 offers better thermal dissipation through a heatsink."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD2NK90ZT4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD2NK90ZT4 when reusing this data.
