Product details

Overview

IPW80R290C3AFKSA1 from Infineon Technologies is a 800 V, 290 mΩ, 17 A (T_C = 25°C) N-channel superjunction MOSFET in TO-247 package, optimized for high-voltage PFC and resonant LLC primary-side switching in industrial SMPS and server power supplies.

For engineers reviewing the IPW80R290C3AFKSA1 datasheet, IPW80R290C3AFKSA1 pinout, IPW80R290C3AFKSA1 application, or IPW80R290C3AFKSA1 equivalent, key selection criteria include R_DS(on) at 10 V gate drive, E_oss = 120 nJ, Q_g = 42 nC, t_rr = 120 ns, and 100% avalanche-rated ruggedness.

Technical Context

This device belongs to Infineon's CoolMOS™ C3 family, featuring charge-compensated superjunction structure with reduced gate charge and output capacitance. It supports hard-switched and soft-switched topologies up to 100 kHz with low conduction and switching losses.

Designed for unclamped inductive switching (UIS) robustness, it delivers 100% rated avalanche energy without derating. Its threshold voltage V_GS(th) = 3.5 V (min) ensures stable turn-on under wide temperature and supply variations in high-reliability power systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - Supports 400 V DC bus designs with ≥2× safety margin for transient overvoltage in telecom/server PSUs.
R_DS(on) max	290 mΩ @ V_GS = 10 V - Enables <1.5 W conduction loss at 17 A continuous drain current in TO-247 thermal environment.
Q_g	42 nC - Reduces gate driver power requirement and enables efficient 100 kHz operation in LLC half-bridge stages.
E_oss	120 nJ @ V_DS = 400 V - Low output charge minimizes turn-off loss and improves ZVS behavior in resonant converters.
t_rr	120 ns - Fast body diode recovery suppresses shoot-through risk and reduces snubber losses in bridge configurations.
UIS Rating	100% rated - Guarantees single-pulse avalanche capability up to I_AR = 17 A without external clamping circuitry.

Pinout & Package

IPW80R290C3AFKSA1 uses the standard TO-247-3L package with isolated tab. Thermal resistance R_thJC = 0.5 K/W enables high-power dissipation with minimal heatsink footprint.

Pin/Terminal	Circuit Role	Design Meaning
DRAIN (Tab)	High-voltage power output node	Electrically connected to metal tab; requires insulated mounting and ≥0.5 mm creepage to adjacent conductors.
SOURCE	Power return reference for channel and gate drive	Low-inductance connection essential for minimizing dV/dt-induced false turn-on during switching transitions.
GATE	Control terminal for channel modulation	Requires 10 V nominal drive; Miller plateau region centered at ~5.5 V enables predictable switching timing control.

Key Features

Feature	Design Value
Superjunction technology	Enables 290 mΩ R_DS(on) at 800 V rating-25% lower on-resistance than prior-generation CoolMOS™ C2 devices.
Reduced Q_g/Q_sw ratio	42 nC total gate charge with 22 nC gate-to-drain charge-improves switching efficiency in high-frequency PFC boost stages.
Fast, soft body diode	120 ns reverse recovery time with low peak reverse recovery current-reduces EMI and eliminates need for external anti-parallel diode in some LLC designs.
100% UIS tested	Each unit undergoes single-pulse avalanche stress test at rated current-ensures field reliability in overload and short-circuit conditions.

Applications

Server Power Supply

Use Scenario: Boost PFC stage in 5 kVA three-phase online UPS with 750 V DC link.

IC Role / Device Role / Timing Role: Fast-switching N-channel switch in continuous conduction mode (CCM) PFC controller interface.

Use Value: 42 nC Q_g allows use of low-cost 2 A gate drivers while maintaining <150 ns turn-on delay across temperature range.

Solar Inverter DC-DC Stage

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW80N80F6	R_DS(on) = 320 mΩ, Q_g = 48 nC, E_oss = 145 nJ	Higher conduction loss and slower switching; requires larger heatsink in >2 kW designs.	Prefer when cost sensitivity outweighs efficiency targets and layout space permits larger thermal solution.
IXTH80N80L2	R_DS(on) = 300 mΩ, Q_g = 52 nC, no UIS rating	Lacks 100% avalanche testing; unsuitable for unclamped inductive loads like motor drives or UPS hold-up.	Select only in tightly controlled, clamped topologies where failure modes are fully mitigated by design.

Compared with STW80N80F6 and IXTH80N80L2, IPW80R290C3AFKSA1 delivers superior efficiency in high-frequency PFC and LLC due to its lower R_DS(on), reduced E_oss, and guaranteed avalanche ruggedness-critical for industrial-grade power system longevity.

FAQ

What is the maximum continuous drain current for IPW80R290C3AFKSA1 at T_C = 100°C?

The maximum continuous drain current is 12.5 A at case temperature 100°C, derated from 17 A at 25°C per the SOA curve. This value accounts for thermal limits of the TO-247 package and junction-to-case thermal resistance of 0.5 K/W, ensuring safe operation without exceeding 150°C maximum junction temperature.

Does IPW80R290C3AFKSA1 require negative gate voltage for reliable turn-off?

No. The device operates reliably with 0 V gate-source voltage for turn-off; its V_GS(th) minimum of 3.5 V ensures no unintended conduction at room temperature. However, applying –5 V enhances noise immunity in high-dV/dt environments such as multi-kW bridge circuits with fast switching edges.

Can IPW80R290C3AFKSA1 replace IPW80R360C3 in an existing design?

Yes, with minor layout review: both share identical TO-247-3L pinout and voltage rating, but IPW80R290C3AFKSA1 offers 20% lower R_DS(on) and 15% lower Q_g. Gate drive strength and thermal margin should be re-evaluated, especially if operating near original design limits.

Is the drain tab electrically isolated in IPW80R290C3AFKSA1?

No-the drain is internally connected to the metal tab. Electrical isolation must be achieved externally using insulating pads or shoulder washers. Clearance and creepage distances must comply with IEC 62368-1 requirements for 800 V working voltage, including ≥4 mm creepage on PCB surfaces adjacent to the tab.
