The 1000 V drain-source rating gives you a solid margin on a 240 VAC input with reflected voltage spikes — you won't be chasing avalanche failures on the first surge test. Continuous drain current is 2.5 A at 25°C case temperature, but the TO-252 package (DPAK) is the limiting factor: at elevated ambient you'll derate toward 1.5 A or so, depending on the copper area on the drain tab. ## Temperature range and package — where this part lives The DPAK (TO-252) footprint is a surface-mount package with a large drain tab — the board layout needs a decent copper pour and thermal vias to pull the heat out.","metaTitle":"STD3NK100Z N-Channel MOSFET, 1000 V, 2.5 A, DPAK","metaDescription":"STD3NK100Z N-Channel 1000 V 2.5 A MOSFET in DPAK.

The STD3NK100ZT4 is the same die in a Tape & Reel package variant — electrically identical, just different reel quantity. If you need a drop-in replacement from another manufacturer, look for a 1000 V N-channel MOSFET in DPAK with similar Rds(on) and gate charge; the ST part's 6 Ohm Rds(on) and 18 nC Qg are the key parametric anchors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD3NK100Z","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD3NK100Z when reusing this data.
