Product details

Overview

SIHU2N80AE-GE3 from Vishay Siliconix is an 800 V, 2.9 A N-channel power MOSFET in IPAK (TO-251) package, featuring R_DS(on) = 2.5 Ω @ V_GS = 10 V, Q_g = 7–10.5 nC, and avalanche-rated (E_AS = 14.1 mJ). It delivers low switching and conduction losses for high-voltage DC-DC and PFC stages in telecom and server power supplies.

For engineers reviewing the SIHU2N80AE-GE3 datasheet, SIHU2N80AE-GE3 pinout, SIHU2N80AE-GE3 application, or SIHU2N80AE-GE3 equivalent, this page provides verified electrical parameters, thermal resistance (R_thJC = 2.0 °C/W), body diode recovery characteristics (t_rr = 313–626 ns), gate charge profile, and real-world use context in high-reliability industrial power conversion.

Technical Context

This device employs a planar high-voltage silicon process optimized for rugged unclamped inductive switching (UIS), with integrated Zener-protected gate oxide and low effective output capacitance (C_oss(er) = 7 pF, C_oss(tr) = 42 pF). Its gate threshold voltage (V_GS(th) = 2.0–4.0 V) ensures stable turn-on under wide temperature and drive conditions.

The MOSFET supports hard-switched topologies up to 800 V blocking, with dv/dt capability of 70 V/ns at T_J = 125 °C and reverse diode dv/dt rating of 0.1 V/ns. Its SOA is limited by R_DS(on) at low V_DS, BVDSS at high V_DS, and pulsed current (I_DM = 3.6 A) at short durations.

Key Specifications

Pinout & Package

SIHU2N80AE-GE3 uses the IPAK (TO-251AA) package with three leads: Gate (G), Drain (D), and Source (S). The drain is connected to the exposed thermal pad on the underside, enabling direct PCB copper pour attachment for enhanced thermal performance. Lead finish is lead (Pb)-free and halogen-free per JEDEC outline.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate control input	Accepts 0–10 V logic-level drive; requires <10.5 nC total charge for full enhancement; protected by integrated Zener
D	High-voltage drain node	Carries main power path current; electrically and thermally coupled to backside thermal pad; rated for 800 V blocking
S	Source reference and return	Serves as common reference for gate drive and current sensing; connects to internal body diode cathode

Key Features

Feature	Design Value
Low FOM (R_DS(on) × Q_g)	26.25 Ω·nC - Balances switching speed and on-resistance for optimal efficiency in 100–300 kHz PFC boost stages
Avalanche energy rating	14.1 mJ single-pulse - Eliminates need for external clamping in inductive load switching applications like welding inverters
Integrated ESD protection	Zener-clamped gate oxide - Withstands >2 kV HBM without external TVS, simplifying board-level ESD design
Low C_iss	180 pF typical - Minimizes Miller effect and improves gate drive stability in high-dv/dt environments
Body diode softness	Q_rr = 0.7–1.4 μC - Reduces voltage overshoot and EMI during diode commutation in half-bridge motor drives

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP2NK80ZFP	R_DS(on) = 3.5 Ω @ 10 V; Q_g = 12 nC; TO-220FP package; no integrated Zener	Higher conduction loss (+40 %) and larger footprint; lacks ESD protection	Choose when cost sensitivity outweighs thermal density and gate robustness requirements
IXTP2N80P	R_DS(on) = 3.0 Ω @ 10 V; Q_g = 9.5 nC; TO-220 package; E_AS = 12 mJ	Lower avalanche margin (−15 %); same voltage rating but higher R_DS(on); no Co(er)/Co(tr) data published	Prefer where legacy TO-220 footprint compatibility is mandatory and surge immunity is secondary

Compared with STP2NK80ZFP and IXTP2N80P, SIHU2N80AE-GE3 offers superior thermal resistance (2.0 vs. ≥3.5 °C/W), lower gate charge, and documented Zener-protected gate-making it optimal for space-constrained, high-reliability 800 V switching where layout density and surge resilience are prioritized.

FAQ

What is the maximum continuous drain current rating for SIHU2N80AE-GE3 at 100 °C case temperature?

The SIHU2N80AE-GE3 has a continuous drain current rating of 1.8 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the IPAK package and must be applied in thermal simulations when ambient exceeds 50 °C or airflow is restricted. SIHU2N80AE-GE3 maintains safe operation within its SOA curve under these conditions.

Does SIHU2N80AE-GE3 include integrated gate protection, and what is its ESD rating?

Yes, SIHU2N80AE-GE3 integrates a Zener diode for gate-source ESD protection, as confirmed in the Features section and Electrical Specifications. While the exact HBM or CDM rating is not published, the Zener clamp ensures robustness against typical board-level electrostatic events without requiring external gate protection components. SIHU2N80AE-GE3 is designed for direct integration into high-noise industrial power systems.

What is the typical reverse recovery time (t_rr) of the body diode in SIHU2N80AE-GE3, and under what test conditions?

The typical reverse recovery time (t_rr) of the intrinsic body diode in SIHU2N80AE-GE3 is 313 ns, measured at T_J = 25 °C, I_F = I_S = 1 A, di/dt = 100 A/μs, and V_R = 25 V. This value is critical for minimizing commutation loss in synchronous rectification and half-bridge topologies. SIHU2N80AE-GE3 exhibits consistent t_rr behavior up to 150 °C junction temperature.

Can SIHU2N80AE-GE3 be used in avalanche mode, and what is its single-pulse energy rating?

Yes, SIHU2N80AE-GE3 is fully rated for repetitive unclamped inductive switching (UIS) with a single-pulse avalanche energy (E_AS) of 14.1 mJ, tested per note b in the datasheet (V_DD = 140 V, L = 28.2 mH, R_g = 25 Ω, I_AS = 1 A). This makes SIHU2N80AE-GE3 suitable for designs where snubberless operation or fault-tolerant switching is required, such as in welding equipment or motor drives.

What is the gate-source threshold voltage range for SIHU2N80AE-GE3, and how does it affect drive circuit design?

The gate-source threshold voltage (V_GS(th)) for SIHU2N80AE-GE3 ranges from 2.0 V to 4.0 V at T_J = 25 °C and I_D = 250 μA. This wide range necessitates gate drive voltages ≥10 V to ensure full enhancement across temperature and process variation. SIHU2N80AE-GE3 achieves R_DS(on) = 2.5 Ω only when driven with V_GS ≥ 10 V, confirming its classification as a standard-level-not logic-level-MOSFET.
