Frequently Asked Questions
What is the maximum drain-source voltage of the STF23NM50N?
The STF23NM50N supports a maximum drain-source breakdown voltage (BVDSS) of 500 V, making it suitable for high-voltage power conversion circuits such as offline SMPS and industrial motor drives operating from rectified mains supplies.
What package options are available for the STF23NM50N?
The STF23NM50N is available in D²PAK (surface-mount), TO-220 (through-hole), and TO-220FP (fully isolated through-hole) packages, allowing designers to choose the best thermal management and PCB layout option for their specific application.
What is the typical on-resistance of the STF23NM50N and how does it affect efficiency?
The STF23NM50N has a typical RDS(on) of 162 mΩ and a maximum of 190 mΩ at 25°C. Lower on-resistance directly reduces conduction power losses (P = I² × RDS(on)), improving converter efficiency, especially at the 17 A maximum drain current rating.
What is the avalanche energy rating of the STF23NM50N?
The STF23NM50N is rated for 254 mJ of avalanche energy (Eas), reflecting the MDmesh II technology's robust ruggedness against unclamped inductive switching events that are common in motor control and relay driver applications.
Can the STF23NM50N be used in automotive applications?
The standard STF23NM50N is an industrial-grade part. For automotive-qualified versions with AEC-Q101 compliance, consult STMicroelectronics' automotive product catalog, as specialized variants with extended qualification may be required for vehicle electronics.
