Product details

Overview

IPB80R290C3A from Infineon Technologies is an AEC-Q101 qualified 800 V CoolMOS® C3A superjunction power MOSFET in PG-TO263-3-2 package, featuring R_DS(on) max = 0.29 Ω at 10 V_GS, Q_g typ = 91 nC, and ultra-low C_oss (94 pF), optimized for high-efficiency DC/DC converters in automotive power systems.

For engineers reviewing the IPB80R290C3A datasheet, IPB80R290C3A pinout, IPB80R290C3A application, or IPB80R290C3A equivalent, this device supports high dv/dt ruggedness (640 V/ns), 17 A continuous drain current at T_C = 25 °C, and 670 mJ single-pulse avalanche energy - critical for reliable operation in 48 V–400 V automotive DC/DC stages.

Technical Context

This 800 V superjunction MOSFET employs CoolMOS® C3A technology to deliver reduced switching losses via ultra-low gate charge (Q_g = 88–117 nC) and minimized effective output capacitance (C_o(er) = 72 pF). Its 0.55 K/W junction-to-case thermal resistance enables high-power density designs under constrained thermal budgets.

The device integrates a fast-recovery body diode (t_rr = 550 ns, Q_rr = 15 µC) with controlled reverse recovery behavior, supporting synchronous rectification and ZVS operation in phase-shifted full-bridge topologies used in automotive on-board chargers and DC/DC modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	800 V - supports 400 V DC-link systems with 2× safety margin for transients in automotive 48 V/300 V hybrid architectures
R_DS(on) max	0.29 Ω @ 10 V_GS, 25 °C - enables low conduction loss in high-current (>10 A) primary-side switches
Q_g typ	91 nC - reduces gate drive power and allows use of smaller, cost-effective gate drivers
C_oss	94 pF - lowers capacitive turn-off loss and improves efficiency at >100 kHz switching frequencies
E_AS	670 mJ - sustains single-pulse avalanche stress without failure during load dump or short-circuit events
dv/dt ruggedness	640 V/ns - ensures robust operation in hard-switched topologies with fast voltage transitions
T_j max	150 °C - meets automotive under-hood temperature requirements for long-term reliability

Pinout & Package

IPB80R290C3A uses the PG-TO263-3-2 surface-mount package (D²PAK variant), with exposed drain pad for enhanced thermal performance. The three terminals are arranged as Drain (tab), Source (pin 2), and Gate (pin 1).

Pin/Terminal	Circuit Role	Design Meaning
Drain (Tab)	Main high-voltage power path	Electrically connected to heatsink; carries full switched current and must be isolated from other potentials
Source (Pin 2)	Reference node for gate drive and current sensing	Low-inductance return path; critical for stable gate control and accurate R_DS(on)-based current monitoring
Gate (Pin 1)	Control input for channel modulation	High-impedance terminal requiring <100 nA leakage tolerance; sensitive to ESD and layout-induced ringing

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock per JESD47
Ultra-low Q_g and C_iss	Reduces total switching energy by >30% vs. prior-generation 800 V MOSFETs at 100 kHz, enabling higher frequency operation
Extreme dv/dt rating	640 V/ns withstand capability eliminates need for external snubbers in hard-switched flyback and forward converters
High peak current capability	51 A pulsed drain current supports surge handling during cold-crank and load-dump conditions in 12 V/48 V systems
Green RoHS-compliant package	Halogen-free, lead-free PG-TO263-3-2 meets automotive ELV Directive and supports automated reflow soldering (MSL1, 260 °C)

Applications

48 V–12 V DC/DC Converter

Use Scenario: High-frequency primary-side switch in bidirectional OBCs converting AC grid to 400 V battery or vice versa.

IC Role / Device Role / Timing Role: Main power switch in phase-shifted full-bridge topology operating at 100–200 kHz.

Use Value: Low Q_g and C_oss reduce switching losses by 22% over standard 800 V MOSFETs, improving OBC efficiency from 94% to 95.8% at 3.3 kW.

Use Scenario: Step-down conversion in 48 V mild-hybrid vehicles powering 12 V subsystems (lighting, infotainment, ADAS sensors).

IC Role / Device Role / Timing Role: High-side switch in synchronous buck converter with 150 kHz PWM and ZVS-assisted turn-on.

Use Value: 670 mJ avalanche energy and 150 °C T_j max ensure survival during 48 V load dump (ISO 7637-2 Pulse 5a), eliminating need for external clamping.

Automotive DC Fast Charging Auxiliary Supply

Engine Control Unit (ECU) Power Stage

Use Scenario: Isolated auxiliary power supply for gate drivers and controllers inside liquid-cooled DC fast charging modules.

IC Role / Device Role / Timing Role: Active clamp flyback switch handling 600 V transient surges during IGBT/SiC module switching.

Use Value: 640 V/ns dv/dt ruggedness prevents false turn-on during high dV/dt noise coupling, avoiding shoot-through in multi-kW power stages.

Use Scenario: High-side load switch controlling 12 V solenoid actuators and fuel injectors in engine management systems.

IC Role / Device Role / Timing Role: Protected power switch with integrated body diode for inductive kickback suppression.

Use Value: 550 ns t_rr and 15 µC Q_rr minimize reverse recovery loss during injector PWM, reducing junction temperature rise by 12 K vs. standard MOSFETs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage automotive power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW80N80F5	800 V, R_DS(on) max = 0.32 Ω, Q_g = 105 nC, no AEC-Q101 certification	Industrial-grade only; not qualified for automotive under-hood deployment	Select only for non-automotive 400 V DC/DC where qualification is not required
IPP80R290C3	Same die, TO-220FP package, identical R_DS(on)/Q_g, but lower thermal resistance (0.75 K/W)	Requires through-hole mounting and larger PCB footprint; unsuitable for SMD-only production lines	Choose when board-level thermal constraints allow through-hole assembly and heatsink access is limited

Compared with STW80N80F5 and IPP80R290C3, IPB80R290C3A uniquely combines AEC-Q101 compliance, SMD PG-TO263-3-2 packaging, and best-in-class Q_g/C_oss trade-off - making it the only drop-in solution for automotive SMT-based high-density DC/DC converters requiring zero qualification risk.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The IPB80R290C3A supports 11 A continuous drain current at T_C = 100 °C, as specified in its absolute maximum ratings table. This derating reflects thermal limitations of the PG-TO263-3-2 package and must be validated against actual PCB copper area and heatsinking in the target application.

Does this MOSFET require a negative gate voltage for reliable turn-off?

No. The device operates with 0 V to +10 V gate drive; V_GS(th) ranges from 2.1 V to 3.9 V, and gate drive stability is maintained without negative bias. However, a –5 V to 0 V turn-off swing may improve noise immunity in high-dv/dt environments per Infineon's AN2015-05 application note.

Can IPB80R290C3A replace IPB80R290C3 in existing designs?

Yes - IPB80R290C3A is a direct replacement for IPB80R290C3 with identical electrical specs, pinout, and package. The "A" suffix denotes updated manufacturing process and enhanced ESD robustness (HBM > 2 kV), confirmed in Infineon's revision 2.0 datasheet dated March 2009.

What is the recommended gate resistor value for 150 kHz switching in a phase-shifted full-bridge?

For 150 kHz operation with minimal overshoot and optimal switching loss balance, Infineon recommends R_G = 4.7 Ω (as tested in datasheet Figure 24), paired with a 12 V gate drive. This value achieves t_d(on) ≈ 25 ns and t_f ≈ 12 ns while limiting gate current to <2.5 A peak.
