Product details
Overview
SIHG24N80AE-GE3 from Vishay Siliconix is an 800 V, 21 A N-channel enhancement-mode Power MOSFET in TO-247AC package, featuring RDS(on) = 0.160 Ω (typ. at VGS = 10 V), Qg = 59 nC (typ.), and avalanche-rated EAS = 127 mJ - optimized for high-voltage switching in telecom power supplies, PFC stages, and PV inverters.
For engineers reviewing the SIHG24N80AE-GE3 datasheet, SIHG24N80AE-GE3 pinout, SIHG24N80AE-GE3 application, or SIHG24N80AE-GE3 equivalent, this device delivers low FOM (RDS(on) × Qg), reduced switching losses via low Coss (65 pF) and Co(er) (52 pF), and robust unclamped inductive switching capability - critical for hard-switched SMPS designs operating above 400 V DC bus.
Technical Context
This MOSFET employs planar high-voltage silicon technology with optimized charge distribution to achieve low effective output capacitance (Co(er) = 52 pF) and fast switching (tr = 44 ns typ., tf = 51 ns typ.) under 640 V VDS conditions. Its gate threshold voltage (VGS(th) = 2–4 V) ensures stable turn-on with standard 10 V gate drivers while maintaining noise immunity.
The integrated body diode exhibits trr = 476 ns (typ.) and Qrr = 7.8 μC (typ.) at TJ = 25 °C, supporting moderate-frequency synchronous rectification and PFC boost operation. Thermal resistance RthJC = 0.6 °C/W enables high-power dissipation in forced-air or heatsink-mounted configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 800 V - supports 640 V DC bus designs with 25 % margin for voltage transients in telecom/PV applications |
| RDS(on) typ. | 0.160 Ω at VGS = 10 V, ID = 10 A - enables <1.6 W conduction loss at 10 A, reducing heatsink requirements |
| Qg typ. | 59 nC - lowers gate drive power and allows use of lower-current gate drivers (e.g., UCC27531) |
| EAS | 127 mJ - rated for repetitive unclamped inductive switching, essential for reliability in hard-switched PFC and motor drives |
| Coss | 65 pF - contributes to low switching loss and stable dv/dt performance (70 V/ns max at TJ = 125 °C) |
| tr/tf | 44/51 ns typ. - supports >100 kHz switching frequencies in resonant and phase-shifted topologies |
| ID cont. (TC = 100 °C) | 13 A - defines usable current in compact heatsink layouts without derating below 100 °C case temperature |
Pinout & Package
SIHG24N80AE-GE3 uses the TO-247AC package - a 3-lead, through-hole, high-voltage power package with isolated drain tab, optimized for thermal transfer to external heatsinks and high-voltage creepage (>8 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives 10 V logic-level gate drive; requires <60 nC total charge for full enhancement; sensitive to ESD (±30 V rating) |
| 2 (Drain) | High-side power terminal | Connected to high-voltage DC bus (up to 800 V); electrically tied to metal tab for direct heatsink mounting |
| 3 (Source) | Power return / reference node | Serves as local ground reference for gate driver; carries full load current (21 A continuous) and diode reverse recovery current |
Key Features
| Feature | Design Value |
|---|---|
| Low figure-of-merit (RDS(on) × Qg) | 9.44 Ω·nC - reduces combined conduction + switching loss, enabling higher efficiency in 1–3 kW SMPS |
| Low effective output capacitance (Co(er)) | 52 pF - minimizes energy loss during turn-off (Eoss ∝ V2 × C), improving light-load efficiency |
| Avalanche energy rating (EAS) | 127 mJ - guarantees safe operation during transient overcurrent events without requiring external snubbers |
| Reduced switching losses | Qgd/Qgs = 2.0 ratio - provides Miller plateau control for predictable dV/dt and reduced shoot-through risk in half-bridge designs |
| Lead (Pb)-free and halogen-free | Complies with RoHS Directive 2011/65/EU and Vishay's material categorization per doc#99912 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW24N80K5 | RDS(on) = 0.18 Ω (typ.), Qg = 65 nC, EAS = 110 mJ, same TO-247 package | Higher conduction loss and lower avalanche rating limit use in high-reliability PFC or surge-prone PV environments | Preferred where cost sensitivity outweighs 12 % RDS(on) penalty and 13 % lower EAS |
| IXTH24N80L | RDS(on) = 0.19 Ω (typ.), Qg = 52 nC, EAS = 105 mJ, TO-247 long leads | Lower Qg improves gate drive efficiency but reduced avalanche margin and higher RDS(on) increase thermal stress at full load | Suitable for space-constrained layouts needing shorter lead form, but requires tighter thermal management |
Compared with STW24N80K5 and IXTH24N80L, SIHG24N80AE-GE3 offers the lowest RDS(on) × Qg FOM and highest EAS, making it optimal for high-efficiency, high-reliability 800 V-class SMPS where thermal headroom and transient robustness are critical.

FAQ
What is the maximum continuous drain current for SIHG24N80AE-GE3 at 100 °C case temperature?
The SIHG24N80AE-GE3 supports 13 A continuous drain current when the case temperature (TC) is maintained at 100 °C, as specified in the Absolute Maximum Ratings table. This rating reflects thermal derating from the 21 A value at TC = 25 °C and must be validated with actual heatsink performance and ambient conditions in the final layout. SIHG24N80AE-GE3 achieves this using its 0.6 °C/W junction-to-case thermal resistance.
Does SIHG24N80AE-GE3 have avalanche capability, and how is it rated?
Yes, SIHG24N80AE-GE3 is fully rated for repetitive unclamped inductive switching (UIS) with a single-pulse avalanche energy (EAS) of 127 mJ under defined test conditions (VDD = 140 V, L = 28.2 mH, Rg = 25 Ω, IAS = 3 A). This rating confirms robustness against transient overcurrents without external protection circuitry. SIHG24N80AE-GE3 meets Vishay's stringent avalanche qualification standards per document 92372.
What is the gate threshold voltage range for SIHG24N80AE-GE3, and why does it matter?
The gate-source threshold voltage (VGS(th)) for SIHG24N80AE-GE3 is specified from 2 V to 4 V at ID = 250 μA. This range ensures reliable turn-on with standard 10 V gate drivers while providing sufficient noise margin against false triggering in noisy power environments. SIHG24N80AE-GE3's VGS(th) stability across temperature (ΔVDS/TJ = 0.8 V/°C) further enhances system predictability in wide-temperature applications.
Can SIHG24N80AE-GE3 be used in place of a logic-level MOSFET?
No, SIHG24N80AE-GE3 is not a logic-level MOSFET; it requires VGS = 10 V for full enhancement and specified RDS(on). Its VGS(th) minimum of 2 V does not imply compatibility with 3.3 V or 5 V microcontroller outputs. Driving SIHG24N80AE-GE3 directly from low-voltage logic will result in incomplete turn-on and excessive conduction loss. SIHG24N80AE-GE3 must be paired with a dedicated gate driver capable of sourcing/sinking ≥1 A peak current.
What is the reverse recovery performance of the body diode in SIHG24N80AE-GE3?
The integral body diode of SIHG24N80AE-GE3 has a typical reverse recovery time (trr) of 476 ns and reverse recovery charge (Qrr) of 7.8 μC at TJ = 25 °C, IF = 12 A, and di/dt = 100 A/μs. These values indicate moderate softness and are suitable for DCM PFC and non-synchronous flyback topologies, but not recommended for high-frequency synchronous rectification without external Schottky clamping. SIHG24N80AE-GE3's diode parameters are fully characterized in the datasheet's "Drain-Source Body Diode Characteristics" section.
