Product details
Overview
SIHG24N80AEF-GE3 from Vishay Siliconix is an 800 V, 20 A N-channel enhancement-mode power MOSFET in TO-247AC package, featuring 0.170 Ω RDS(on) at VGS = 10 V, 90 nC total gate charge, and fast body diode with 127 ns reverse recovery time - optimized for high-efficiency PFC and SMPS stages in telecom and server power supplies.
For engineers reviewing the SIHG24N80AEF-GE3 datasheet, SIHG24N80AEF-GE3 pinout, SIHG24N80AEF-GE3 application, or SIHG24N80AEF-GE3 equivalent, key selection criteria include avalanche-rated UIS capability (127 mJ), low Co(er) of 51 pF for reduced switching loss, and validated performance under 100 V/ns dv/dt stress in hard-switched topologies.
Technical Context
This MOSFET employs planar high-voltage silicon technology with optimized charge distribution to achieve low figure-of-merit (RDS(on) × Qg = 15.3 Ω·nC). Its fast intrinsic body diode supports ZVS/ZCS operation in resonant converters and reduces snubber losses in hard-switched PFC boost stages.
The device is rated for repetitive unclamped inductive switching (UIS) up to 127 mJ and exhibits controlled dv/dt immunity (100 V/ns at TJ = 125 °C), enabling robust operation in high-di/dt industrial motor drive half-bridges and solar inverter DC-link switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 800 V - supports 650 V bus designs with 23 % voltage margin for transient overvoltage tolerance |
| RDS(on) typ @ 25 °C | 0.170 Ω - enables <1.7 W conduction loss at 10 A continuous drain current |
| Qg max | 90 nC - determines gate driver power requirement (~1.8 mW avg. at 100 kHz, VGS swing = 10 V) |
| EAS | 127 mJ - ensures single-pulse avalanche ruggedness without derating in PFC choke failure scenarios |
| trr | 127 ns typical - minimizes commutation loss and diode reverse recovery overshoot in bridge-leg switching |
| RthJC | 0.6 °C/W - allows 208 W dissipation with ≤120 °C case-to-ambient ΔT using standard heatsink mounting |
| ID cont @ TC = 100 °C | 13 A - defines usable current limit in thermally constrained 1U server PSU layouts |
Pinout & Package
TO-247AC package: isolated tab (drain), vertical lead orientation, 3-pin through-hole mounting with 2.54 mm lead pitch. Tab is electrically connected to drain terminal and requires insulated mounting hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Receives 10 V logic-level drive; threshold voltage 2–4 V ensures reliable turn-on with standard PWM controllers |
| D (Drain) | High-side power switch node | Connected to TO-247 tab; must be electrically isolated from heatsink; handles full 800 V blocking and 46 A pulsed current |
| S (Source) | Power return reference | Serves as local ground for gate drive loop; low-inductance connection critical to suppress ringing during 210 A/μs di/dt events |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) × Qg FOM | 15.3 Ω·nC - directly reduces combined conduction + switching loss in 100–300 kHz PFC stages |
| Fast body diode (trr = 127 ns) | Enables zero-voltage switching in LLC resonant converters without external SiC diode replacement |
| Avalanche energy rating (EAS = 127 mJ) | Eliminates need for external clamping circuits in inductive load switching applications like welding inverters |
| Low effective output capacitance (Co(er) = 51 pF) | Reduces turn-off energy loss by ~35 % vs. standard 800 V MOSFETs with comparable RDS(on) |
| dv/dt immunity (100 V/ns) | Prevents false turn-on in high-noise motor drive half-bridges without gate resistors > 10 Ω |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW20NK80Z | RDS(on) = 0.38 Ω (higher), Qg = 75 nC, no UIS rating specified | Lacks avalanche energy specification; requires external clamping in inductive loads | Lower cost option where avalanche ruggedness is not required and thermal budget allows higher RDS(on) |
| IXTH24N80L | RDS(on) = 0.19 Ω, Qg = 105 nC, trr = 210 ns (slower), EAS = 110 mJ | Higher switching loss due to larger Qg and slower diode; lower avalanche margin | Better suited for lower-frequency (<50 kHz) motor drives where diode speed is less critical |
Compared with STW20NK80Z and IXTH24N80L, SIHG24N80AEF-GE3 delivers superior balance of low conduction loss, fast diode recovery, and guaranteed avalanche ruggedness - making it the preferred choice for high-frequency, high-reliability PFC and inverter applications demanding both efficiency and fault tolerance.

FAQ
What is the maximum continuous drain current rating for SIHG24N80AEF-GE3 at 100 °C case temperature?
The SIHG24N80AEF-GE3 has a maximum continuous drain current (ID) of 13 A when the case temperature (TC) is maintained at 100 °C. This rating is derived from its 208 W power dissipation limit and 0.6 °C/W junction-to-case thermal resistance, ensuring safe operation within the -55 °C to +150 °C junction temperature range. The SIHG24N80AEF-GE3 must be mounted on a heatsink capable of maintaining TC ≤ 100 °C under full-load conditions.
Does SIHG24N80AEF-GE3 have avalanche capability, and how is it specified?
Yes, SIHG24N80AEF-GE3 is fully rated for repetitive unclamped inductive switching (UIS) with a single-pulse avalanche energy (EAS) of 127 mJ under standardized test conditions (VDD = 140 V, L = 28.2 mH, Rg = 25 Ω, IAS = 3 A, starting TJ = 25 °C). This specification confirms robustness against inductive turn-off transients without external protection, a key requirement for SIHG24N80AEF-GE3 in PFC and motor drive applications.
What is the typical reverse recovery time (trr) of the body diode in SIHG24N80AEF-GE3, and under what conditions is it measured?
The typical reverse recovery time (trr) of the integral body diode in SIHG24N80AEF-GE3 is 127 ns, measured at TJ = 25 °C with forward current IF = IS = 10 A, di/dt = 100 A/μs, and reverse voltage VR = 400 V. This fast recovery characteristic is critical for minimizing commutation loss and voltage overshoot in bridge-leg configurations, directly supporting the SIHG24N80AEF-GE3's use in high-frequency resonant and hard-switched topologies.
Is SIHG24N80AEF-GE3 compatible with standard TO-247AC footprints and mounting hardware?
Yes, SIHG24N80AEF-GE3 uses the industry-standard TO-247AC package with 2.54 mm lead pitch and identical mechanical dimensions to JEDEC TO-247 variants. Its drain-connected tab requires electrical isolation from the heatsink via mica or ceramic washer, and the device is qualified for soldering at 260 °C peak for 10 seconds. Mounting torque and thermal interface material selection must follow Vishay's guidelines to maintain the SIHG24N80AEF-GE3's specified RthJC of 0.6 °C/W.
How does the effective output capacitance (Co(er)) of SIHG24N80AEF-GE3 impact switching performance?
The SIHG24N80AEF-GE3 features a low effective output capacitance (Co(er)) of 51 pF, measured from VDS = 0 V to 480 V. This parameter directly determines turn-off energy loss (Eoff ∝ Co(er) × VDS²), enabling up to 35 % lower switching loss than comparable 800 V MOSFETs. As a result, the SIHG24N80AEF-GE3 supports higher operating frequencies in PFC and inverter stages without compromising thermal performance.
