Product details

Overview

IPW80R290C3AXKSA1 from Infineon Technologies is an 800 V, 0.29 Ω R_DS(on)max automotive-qualified CoolMOS® C3A superjunction N-channel power MOSFET in PG-TO247-3 package, optimized for high-efficiency DC/DC converters in engine control units and on-board chargers. It delivers 17 A continuous drain current at T_C = 25 °C, 91 nC typical gate charge, and 670 mJ single-pulse avalanche energy.

For engineers reviewing the IPW80R290C3AXKSA1 datasheet, IPW80R290C3AXKSA1 pinout, IPW80R290C3AXKSA1 application, or IPW80R290C3AXKSA1 equivalent, key selection criteria include its AEC-Q101 qualification, dv/dt ruggedness up to 4 V/ns (reverse diode), 5.5 V gate plateau voltage, and low effective output capacitance (C_o(er) = 72 pF) enabling fast switching in 400–640 V bus systems.

Technical Context

This CoolMOS® C3A device uses charge-compensation technology to achieve ultra-low Q_g (91 nC typ.) and reduced C_iss (2300 pF) while maintaining 800 V blocking capability. Its gate threshold voltage (2.1–3.9 V) and 5.5 V plateau support robust gate drive design with standard 10 V logic-level drivers.

The integrated body diode features 1.2 V forward voltage at I_F = 17 A and 550 ns reverse recovery time, enabling synchronous rectification in isolated DC/DC topologies. Thermal resistance R_thJC is 0.55 K/W, supporting high-power density designs with active heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	800 V - supports 640 V DC-link operation with 25% margin for transient overvoltage in automotive traction inverters and OBCs.
R_DS(on) max	0.29 Ω @ T_j = 25 °C - enables <1.7 W conduction loss at 11 A, critical for thermal management in sealed ECUs.
Q_g typ	91 nC - reduces gate driver power demand and switching losses in 100–300 kHz DC/DC phases.
E_AS	670 mJ - withstands single-pulse inductive energy without failure during load dump or short-circuit events.
dv/dt rating	4 V/ns (diode) - prevents false turn-on in high-noise engine bay environments with fast-rising transients.
T_j range	−40 to 150 °C - certified for under-hood deployment per AEC-Q101 Grade 0 requirements.
R_thJC	0.55 K/W - allows >100 W dissipation with ≤55 K temperature rise across junction-to-case interface.

Pinout & Package

IPW80R290C3AXKSA1 is housed in a PG-TO247-3 plastic package with isolated mounting flange, rated for lead-free soldering at 260 °C (10 s). The case serves as the drain terminal, enabling direct thermal coupling to heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal (S)	Low-side reference node; connects to PCB ground plane or source return path with minimal inductance.
Pin 2 (Gate)	Control input (G)	High-impedance MOSFET gate; requires <100 nA leakage current handling and 0.85 Ω internal gate resistance.
Pin 3 (Drain)	Power output (D)	Case-connected drain; electrically and thermally tied to heatsink-requires isolation bushing if heatsink is grounded.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per Grade 0.
Ultra-low Q_g & C_iss	91 nC Q_g, 2300 pF C_iss - cuts switching losses by >30% vs. previous-gen 800 V MOSFETs at 200 kHz.
High dv/dt ruggedness	4 V/ns (diode), >640 V V_DS slew rate tolerance - eliminates need for external snubbers in high-di/dt motor drive stages.
Enhanced avalanche capability	670 mJ E_AS - sustains repetitive fault conditions in battery disconnect switches without parametric shift.
Low R_DS(on) × Q_g figure-of-merit	26.4 Ω·nC - improves power density in compact 3.3 kW OBC half-bridge modules.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW80N80F6	800 V, 0.32 Ω R_DS(on), 105 nC Q_g, no AEC-Q101 certification	Industrial UPS and solar inverters only; not approved for automotive safety-critical functions	Select when cost sensitivity outweighs automotive qualification and lower switching loss is acceptable.
IPP80R290C3	Same die, TO-220FP package, 1.2 K/W R_thJC, 11 A I_D rating	Limited to <40 W dissipation; suitable for non-hermetic cabin modules only	Choose for space-constrained consumer-grade EVSE controllers where thermal performance is secondary.

Compared with STW80N80F6 and IPP80R290C3, IPW80R290C3AXKSA1 uniquely combines AEC-Q101 compliance, lowest R_thJC (0.55 K/W), and highest E_AS (670 mJ), making it the only option qualified for under-hood 400 V DC/DC converters demanding both reliability and power density.

FAQ

What is the maximum allowable gate-source voltage for IPW80R290C3AXKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation above +20 V risks permanent gate oxide damage, while sustained negative voltage below −20 V may cause threshold shift. Recommended drive is 0 V to +10 V for optimal R_DS(on) and switching speed balance.

Does IPW80R290C3AXKSA1 require a gate resistor for automotive applications?

Yes-a 4.7 Ω series gate resistor is specified in the datasheet for 100–300 kHz switching with controlled dv/dt and EMI. Lower values increase switching speed but raise EMI and risk oscillation; higher values reduce losses but extend t_d(off) to 72 ns, impacting efficiency in high-frequency designs.

How does the reverse diode performance compare to discrete Schottky alternatives?

The integrated body diode has V_SD = 1.2 V at 17 A and t_rr = 550 ns-higher forward drop and slower recovery than 45 V Schottkys, but sufficient for freewheeling in hard-switched buck converters where synchronous rectification isn't used. Not suitable for high-frequency ZVS topologies.

Can IPW80R290C3AXKSA1 be paralleled for higher current capacity?

Yes-its positive temperature coefficient of R_DS(on) (0.67 Ω @ 150 °C) enables stable current sharing. Layout must ensure matched gate loop inductance and symmetrical thermal paths; derate total current by 15% versus sum of individual ratings to account for thermal coupling and parameter spread.
