Product details
Overview
SUA70090E-E3 from Vishay Siliconix is an N-channel 100 V (D-S) power MOSFET in a Thin-Lead TO-220 FULLPAK package, rated for 42.8 A continuous drain current at TJ = 150 °C, with RDS(on) = 0.0093 Ω at VGS = 10 V and Qg = 33 nC - optimized for high-efficiency secondary synchronous rectification in AC/DC power supplies.
For engineers reviewing the SUA70090E-E3 datasheet, SUA70090E-E3 pinout, SUA70090E-E3 application, or SUA70090E-E3 equivalent, this device delivers low conduction loss, fast switching via Qgd/Qgs < 1 ratio, and robust avalanche energy rating (EAS = 80 mJ), supporting design of compact, thermally constrained DC/DC converters and motor drive switches.
Technical Context
This ThunderFET® MOSFET employs planar silicon technology with fully characterized gate charge profile (Qg = 33 nC, Qgd = 7.5 nC, Qgs = 8.8 nC) and tightly controlled RDS(on) distribution (0.0077–0.0093 Ω at VGS = 10 V). Its 100 % Rg and UIS testing ensures gate integrity and ruggedness under transient stress.
The device features a body diode with VSD = 0.8–1.5 V at IF = 10 A and trr = 77–116 ns, enabling efficient freewheeling in hard-switched topologies. Thermal resistance RthJC = 3.5 °C/W supports high-power density mounting on FR4 PCBs with minimal heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 100 V - supports input voltage rails up to 85 V DC in offline SMPS and 48 V bus systems without derating. |
| RDS(on) max | 0.0093 Ω at VGS = 10 V - enables ≤ 4 W conduction loss at 20 A, critical for thermal management in enclosed power tools. |
| ID continuous | 42.8 A at TC = 25 °C - sustains high-current motor drive pulses without external heatsink when mounted on 1"² FR4 PCB. |
| Qg | 33 nC - reduces gate drive power and allows use of low-cost, low-current drivers in 100–500 kHz DC/DC converters. |
| EAS | 80 mJ - withstands repetitive inductive switching surges in motor control H-bridges without failure. |
| tr/tf | 27/45 ns - minimizes switching transition losses and EMI generation in high-frequency synchronous rectifiers. |
| VGS(th) | 2–4 V - ensures reliable turn-on with standard 5 V or 3.3 V logic-level gate drivers in isolated gate-drive circuits. |
Pinout & Package
Package: Thin-Lead TO-220 FULLPAK - 3-pin through-hole package with exposed drain tab for direct thermal coupling to heatsink or copper pour; lead (Pb)-free and halogen-free per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Electrically connected to metal tab; must be electrically isolated from chassis unless system ground reference permits; primary thermal path to PCB or heatsink. |
| Source | Reference node for gate drive and current sensing | Low-inductance return path; used for Kelvin source connection in precision current monitoring; ties to power ground plane. |
| Gate | Control terminal for channel modulation | High-impedance input requiring <3.5 Ω series gate resistor to damp ringing; sensitive to ESD (±20 V absolute max). |
Key Features
| Feature | Design Value |
|---|---|
| Qgd/Qgs < 1 | Reduces Miller-induced shoot-through risk and improves controllability during hard switching in half-bridge configurations. |
| 100 % Rg tested | Guarantees gate resistance between 0.7–7 Ω, ensuring predictable gate drive timing and minimizing layout sensitivity. |
| 100 % UIS tested | Validates unclamped inductive switching capability up to 40 A and 80 mJ, eliminating need for external snubbers in motor drives. |
| ThunderFET® architecture | Optimized cell layout and termination reduce RDS(on) × Qg figure-of-merit to 307 Ω·nC, improving efficiency in 100–300 kHz converters. |
| Body diode trr | 77 ns typical reverse recovery time enables clean commutation in synchronous buck converters without cross-conduction penalties. |

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 |
|---|---|---|---|
| IRF3205PBF | RDS(on) = 0.008 Ω @ 10 V but Qg = 71 nC; TO-220 (standard lead), not FULLPAK; RthJC = 3.0 °C/W. | Higher gate charge increases driver loss and limits max switching frequency to ~150 kHz vs. 300 kHz for SUA70090E-E3. | Prefer SUA70090E-E3 where high-frequency efficiency and thermal performance on thin PCBs are prioritized. |
| STP110N10F7 | RDS(on) = 0.0075 Ω @ 10 V, Qg = 42 nC; TO-220FP package; lower VGS(th) (1–2.5 V); no UIS rating published. | Lacks documented avalanche ruggedness; unsuitable for motor drive inductive loads without external clamping. | Prefer SUA70090E-E3 for applications requiring guaranteed UIS performance and stable threshold across temperature. |
Compared with IRF3205PBF and STP110N10F7, SUA70090E-E3 offers superior Qgd/Qgs ratio for cleaner switching, verified UIS endurance, and thinner lead form factor for improved PCB thermal relief - making it optimal for space- and efficiency-critical 200–500 kHz power stages.

FAQ
What is the maximum continuous drain current rating for SUA70090E-E3 at 70 °C case temperature?
The SUA70090E-E3 supports 34.2 A continuous drain current at TC = 70 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the Thin-Lead TO-220 FULLPAK package under sustained high-power operation and must be applied when ambient or heatsink conditions elevate case temperature above 25 °C.
Does SUA70090E-E3 have a specified reverse recovery time for its integrated body diode?
Yes, SUA70090E-E3 specifies trr = 77–116 ns (typ./max.) under test conditions of IF = −10 A and dI/dt = 100 A/μs. This value is measured directly on the intrinsic body diode and is critical for evaluating commutation behavior in synchronous rectifier and half-bridge applications.
Is SUA70090E-E3 suitable for use with 5 V gate drive voltage?
SUA70090E-E3 has a gate threshold voltage range of 2–4 V and delivers RDS(on) = 0.0100 Ω at VGS = 7.5 V and ID = 15 A. While it will turn on with 5 V drive, full enhancement requires ≥7.5 V for specified low RDS(on); using 5 V results in higher conduction loss and reduced current capability.
What is the avalanche energy rating of SUA70090E-E3, and under what conditions is it validated?
SUA70090E-E3 is rated for single-pulse avalanche energy EAS = 80 mJ with L = 0.1 mH, tested per JEDEC JESD24-1. This rating is confirmed by 100 % UIS testing during production, ensuring each unit can safely absorb inductive energy without degradation in motor drive or relay-switching applications.
How does the Thin-Lead TO-220 FULLPAK package of SUA70090E-E3 differ from standard TO-220 in thermal performance?
The Thin-Lead TO-220 FULLPAK package of SUA70090E-E3 reduces leadframe thickness to improve thermal coupling between die and PCB copper, achieving RthJC = 3.5 °C/W - identical to standard TO-220 - but with enhanced solder joint reliability and lower parasitic inductance due to shorter internal leads and full plastic encapsulation over the tab.
