Product details
Overview
SUD50N024-09P-E3 from Vishay Siliconix is an N-channel TrenchFET power MOSFET rated for 22 V drain-source voltage, 49 A continuous drain current at TC = 25 °C, and 0.0095 Ω rDS(on) at VGS = 10 V - optimized for high-efficiency PWM in high-side synchronous buck DC/DC converters used in desktop and server power supplies.
For engineers reviewing the SUD50N024-09P-E3 datasheet, SUD50N024-09P-E3 pinout, SUD50N024-09P-E3 application, or SUD50N024-09P-E3 equivalent, key selection criteria include its 22 V VDS rating, 0.0095 Ω on-resistance at 10 V gate drive, 175 °C maximum junction temperature, TO-252 package thermal performance, and diode recovery characteristics for synchronous rectification.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve low conduction loss and fast switching with 10.5 nC total gate charge and 275 pF reverse transfer capacitance (Crss), enabling efficient operation in high-frequency synchronous buck topologies. Its gate threshold voltage range (0.8–3.0 V) supports robust 4.5 V logic-level drive compatibility while maintaining noise immunity.
The device features a source-drain diode with 1.2–1.5 V forward voltage at 50 A and 35–70 ns reverse recovery time, critical for minimizing shoot-through and body-diode conduction losses in high-side configurations. Drain-connected tab enhances thermal path to PCB copper in TO-252 surface-mount mounting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRLHS6242TRPBF | 20 V VDS, 0.0065 Ω rDS(on) @ 4.5 V, 5 mm × 6 mm PQFN package | Lower voltage rating; better suited for 12 V input systems with space-constrained layouts | Select when board space is limited and input voltage ≤16 V; requires different footprint and layout |

FAQ
What is the maximum continuous drain current rating for SUD50N024-09P-E3 at 100 °C case temperature?
The SUD50N024-09P-E3 has a continuous drain current rating of 34 A at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-252 package and silicon die, not package current-carrying capacity alone. The SUD50N024-09P-E3 must be mounted on adequate PCB copper to sustain this current without exceeding 175 °C junction temperature.
Does SUD50N024-09P-E3 support 4.5 V gate drive in high-side synchronous buck applications?
Yes, the SUD50N024-09P-E3 is fully characterized for 4.5 V gate drive, with rDS(on) = 0.017 Ω at ID = 20 A and VGS = 4.5 V. Its gate threshold voltage range (0.8–3.0 V) ensures strong enhancement-mode turn-on under typical 4.5 V logic-level controller outputs, making the SUD50N024-09P-E3 suitable for modern multiphase VRMs using 5 V or 3.3 V gate drivers.
What is the thermal resistance from junction to case (RthJC) for SUD50N024-09P-E3?
The SUD50N024-09P-E3 has a maximum junction-to-case thermal resistance of 3.8 °C/W, with a typical value of 3.1 °C/W. This low RthJC is achieved via the drain-connected metal tab in the TO-252 package, enabling efficient heat transfer to the PCB copper pour or external heatsink - a key parameter for thermal design of the SUD50N024-09P-E3 in high-power density VRMs.
Is SUD50N024-09P-E3 suitable for use as a synchronous rectifier in a high-side configuration?
Yes, the SUD50N024-09P-E3 is explicitly designed for high-side synchronous buck DC/DC conversion, as confirmed in its Applications section. Its low rDS(on), fast switching parameters (Qgd = 4.0 nC, trr = 35–70 ns), and source-drain diode characteristics make the SUD50N024-09P-E3 appropriate for replacing Schottky diodes in high-efficiency topologies where body-diode conduction must be minimized.
What does the "-E3" suffix indicate in SUD50N024-09P-E3?
The "-E3" suffix denotes that the SUD50N024-09P-E3 is manufactured with lead-free terminations and complies with RoHS Directive 2011/65/EU. It specifies a matte tin (Sn) plating over copper leads, qualified for standard Pb-free reflow soldering profiles per JEDEC J-STD-020, distinguishing it from leaded versions like SUD50N024-09P.
