Frequently asked questions
What is the Rds(on) of STP80NF12?
Maximum on-resistance is 18 mOhm at 40 A drain current with 10 V gate drive. This is the value to use for worst-case conduction loss calculations.
What is the replacement for STP80NF12?
No official direct replacement is listed by STMicroelectronics. The STripFET™ II family includes other 120 V N-channel TO-220 parts with similar current ratings; parametric search on Vdss, Id, and Rds(on) yields the closest match. For a cross-reference, submit an RFQ with your target specs.
