Product details

Overview

SUD70090E-GE3 from Vishay Siliconix is an N-channel 100 V, 50 A TO-252 (DPAK) power MOSFET optimized for high-efficiency switching in DC/DC converters and motor drive switches, featuring 7.5 mΩ R_DS(on) at V_GS = 10 V, 33 nC total gate charge, and 175 °C maximum junction temperature.

For engineers reviewing the SUD70090E-GE3 datasheet, SUD70090E-GE3 pinout, SUD70090E-GE3 application, or SUD70090E-GE3 equivalent, this device is selected for high-current, thermally demanding power-switching roles where low conduction loss, robust avalanche capability (80 mJ), and Pb-free/halogen-free compliance are required.

Technical Context

This MOSFET employs a planar silicon process with ThunderFET® technology to achieve low Q_gd/Q_gs ratio (<1), enabling fast, low-loss switching transitions. Its 1.2 °C/W junction-to-case thermal resistance supports high-power operation when mounted on copper-clad PCBs or heatsinks.

The device is fully characterized for unclamped inductive switching (UIS), 100% R_g tested, and rated for continuous drain current up to 50 A at T_C = 25 °C and 70 °C - limited by package thermal capacity rather than silicon limits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports bus voltages up to 48 V nominal systems with 2× safety margin
R_DS(on) max	8.9 mΩ at V_GS = 10 V - enables <1 W conduction loss at 15 A continuous drain current
I_D continuous	50 A at T_C = 25 °C - requires ≥1"² FR4 PCB copper area or heatsink for sustained operation
Q_g typ	33 nC - determines gate driver power requirement and switching speed in hard-switched topologies
E_AS	80 mJ - ensures reliable operation under inductive load turn-off without external snubbers
R_thJC	1.2 °C/W - allows direct thermal path to heatsink via drain-tab mounting, critical for >30 W dissipation
T_J max	+175 °C - enables operation in automotive under-hood or industrial motor-control environments

Pinout & Package

TO-252AA (DPAK) surface-mount package with exposed drain tab for thermal and electrical connection. Dimensions per Vishay Doc. 71197 (Rev. 03-Oct-2022); drain tab occupies full underside of package and must be soldered to large copper pour or heatsink.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Accepts 0–20 V logic-level or PWM drive; threshold voltage 2–4 V enables compatibility with 3.3 V and 5 V microcontrollers
D (Drain)	High-side power output	Internally connected to exposed metal tab - must be electrically and thermally coupled to system ground plane or heatsink
S (Source)	Power return reference	Serves as local ground reference for gate drive; source inductance directly impacts switching stability and dV/dt immunity

Key Features

Feature	Design Value
ThunderFET® architecture	Optimized cell layout reduces Q_gd/Q_gs ratio to <1, minimizing Miller-induced switching delay and improving EMI performance
100 % R_g and UIS tested	Ensures gate resistance consistency across production lots and guarantees single-pulse avalanche ruggedness to 80 mJ
Lead (Pb)-free and halogen-free	Complies with RoHS Directive 2011/65/EU and JEDEC JS709E, suitable for consumer, industrial, and automotive applications
Drain-connected tab	Enables direct thermal coupling to PCB copper or external heatsink, reducing junction-to-ambient thermal resistance by up to 33× vs. junction-to-ambient alone

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
IRF7470PBF	Higher R_DS(on) (11 mΩ @ 10 V), TO-252 package, same V_DS and I_D ratings	Lower efficiency in high-current continuous operation due to +23 % conduction loss	Select when legacy design validation exists and minor efficiency trade-off is acceptable
STP75NF75	TO-220 package, higher R_DS(on) (7.5 mΩ @ 10 V but rated at 75 A), no Pb-free/halogen-free certification stated	Requires through-hole assembly and larger board footprint; not compliant with latest environmental directives	Select only for cost-sensitive, non-regulated industrial applications with manual assembly

Compared with IRF7470PBF and STP75NF75, the SUD70090E-GE3 delivers superior thermal performance via its optimized DPAK thermal path, tighter gate charge distribution, and guaranteed halogen-free compliance - making it preferred for high-density, thermally constrained, and regulated power systems.

FAQ

What is the maximum continuous drain current rating for SUD70090E-GE3 at 70 °C case temperature?

The SUD70090E-GE3 is rated for 50 A continuous drain current at both T_C = 25 °C and T_C = 70 °C, as confirmed in the Absolute Maximum Ratings table. This rating is package-limited and independent of junction temperature - meaning thermal design must ensure case temperature does not exceed 70 °C to sustain full 50 A operation. The SUD70090E-GE3 achieves this via its low R_thJC of 1.2 °C/W and drain-tab thermal path.

Does SUD70090E-GE3 support logic-level gate drive?

Yes, the SUD70090E-GE3 has a gate threshold voltage (V_GS(th)) range of 2–4 V, enabling reliable turn-on with standard 3.3 V or 5 V logic-level signals. However, to achieve its specified 8.9 mΩ R_DS(on), a V_GS of 10 V is required. The SUD70090E-GE3 is not a true logic-level MOSFET for low-R_DS(on) operation but offers partial logic compatibility for control signaling.

What is the avalanche energy rating of SUD70090E-GE3 and how is it tested?

The SUD70090E-GE3 is rated for 80 mJ single-pulse avalanche energy (E_AS) with L = 0.1 mH, tested per JEDEC standard JESD24-1. This rating is guaranteed by 100 % UIS testing in production. The SUD70090E-GE3 uses rugged silicon design and internal layout to absorb inductive energy safely during switching transients, eliminating need for external clamping in many motor and converter designs.

Is SUD70090E-GE3 compatible with automated SMT reflow processes?

Yes, the SUD70090E-GE3 is qualified for standard lead-free reflow profiles (per J-STD-020), including peak temperatures up to 260 °C. Its TO-252AA package meets IPC-7351B land pattern recommendations (see Vishay Application Note 826), and the SUD70090E-GE3's Pb-free/halogen-free construction ensures compatibility with Class 3 assembly requirements and long-term reliability in automated manufacturing.

How does the Q_gd/Q_gs ratio benefit switching performance in SUD70090E-GE3?

The SUD70090E-GE3 features a Q_gd/Q_gs ratio < 1 - a key ThunderFET® characteristic that reduces Miller plateau duration and improves controllability during turn-off. This lowers switching losses, suppresses parasitic oscillation, and enhances dV/dt immunity. For the SUD70090E-GE3, typical Q_gd is 7.5 nC and Q_gs is 8.8 nC, directly contributing to its fast 36 ns turn-off delay and 45 ns fall time.
