The TO-220 through-hole package suits point-of-load and bulk-power stages where heatsink mounting is standard. The 400 mOhm Rds(on) at 4.5 A, 10 V is the figure to use for conduction-loss calculations in a 300 V bus application. ## Active lifecycle — no LTB concern No last-time-buy or end-of-life notice is in effect, making it suitable for both new-design-in and ongoing production BOMs. The SuperMESH™ series continues as a current portfolio line from STMicroelectronics.","metaTitle":"STP12NK30Z MOSFET, N-Channel 300V 9A TO-220, Active","metaDescription":"STP12NK30Z N-channel MOSFET, 300V Vdss, 9A Id, 400mOhm Rds(on).
