Product details

Overview

AUIRFR4620 from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in D-Pak (TO-252AA) package, rated for 200 V V_DS, 24 A continuous drain current at T_C = 25°C, and 64 mΩ typical R_DS(on) at V_GS = 10 V. It operates up to 175°C junction temperature and supports repetitive avalanche energy up to 113 mJ, making it suitable for high-reliability DC-DC converters and motor control stages in engine management systems.

For engineers reviewing the AUIRFR4620 datasheet, AUIRFR4620 pinout, AUIRFR4620 application, or AUIRFR4620 equivalent, key selection criteria include its 175°C thermal rating, 54 V/ns diode recovery dv/dt capability, 7.9 nC Q_gd for fast switching, and automotive qualification per AEC-Q101 standards - all critical for under-hood power stage design.

Technical Context

This MOSFET employs advanced planar silicon process technology to achieve ultra-low on-resistance density and robust dynamic performance. Its gate threshold voltage (3.0–5.0 V) ensures stable turn-on with standard 5 V or 10 V logic-level drivers, while the 2.6 Ω internal gate resistance helps dampen ringing during high-speed switching.

The device integrates a co-packaged body diode with 1.3 V forward voltage at 15 A and 78 ns reverse recovery time at 25°C, enabling efficient synchronous rectification and freewheeling in buck and half-bridge topologies. Repetitive avalanche operation is explicitly permitted up to T_jmax, validated by thermal-limited EAS testing at 113 mJ.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	200 V - Withstands transient overvoltages up to 200 V in automotive 12 V/24 V systems without breakdown.
R_DS(on) typ.	64 mΩ at V_GS = 10 V, I_D = 15 A - Enables <1.5 W conduction loss at 15 A, reducing heatsink requirements.
I_D cont. @ T_C = 25°C	24 A - Supports high-current loads such as fuel injector drivers and HVAC blower motors.
Q_gd	7.9 nC - Low gate-drain charge minimizes Miller-induced switching delay and improves hard-switching efficiency.
T_J max	175°C - Certified for under-hood operation where ambient temperatures exceed 105°C.
EAS	113 mJ - Allows safe unclamped inductive switching in relay drivers and solenoid controls without external snubbers.
dv/dt (diode)	54 V/ns - Ensures reliable commutation in high-di/dt environments like brushless DC motor phase legs.

Pinout & Package

D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal enhancement and mechanical stability. Standard footprint per Infineon's IR package drawing; solderable per IPC-J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control input	Receives 0–10 V drive signal; 2.6 Ω internal resistance reduces gate oscillation risk.
D (Drain)	High-side power path	Connected to load supply rail; electrically tied to exposed backside metal for low-inductance heat sinking.
S (Source)	Return path / reference node	Serves as local ground reference for gate drive; must be routed with low inductance to minimize switching overshoot.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for engine control, transmission, and chassis applications with full traceability.
Repetitive avalanche rating	Validated for repeated unclamped inductive switching up to T_jmax, eliminating need for external clamping circuits.
Thermal derating factor	0.96 W/°C - Enables predictable power reduction above 25°C case temperature for thermal margin planning.
Body diode softness	Q_rr = 294 nC at 25°C - Low stored charge minimizes voltage spikes and EMI during diode commutation.
Lead-free & RoHS	Compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile.

Applications

Engine Control Unit (ECU) Injector Driver

Automotive HVAC Blower Motor Controller

Use Scenario: High-side switching of 12 V fuel injectors with peak currents up to 20 A and 1 ms pulse widths.

IC Role / Device Role / Timing Role: Power switch controlling coil energization; handles repetitive 200 V flyback transients during de-energization.

Use Value: 175°C rating ensures reliability at ECU board temperatures >125°C; 113 mJ EAS absorbs inductive kickback without snubber.

Use Scenario: PWM-driven 24 V blower motor in climate control systems operating continuously at 15 A.

IC Role / Device Role / Timing Role: Low-side switch in H-bridge configuration; switches at 20 kHz with minimal conduction loss.

Use Value: 64 mΩ R_DS(on) limits I²R loss to <1.4 W at 15 A, reducing thermal stress on PCB copper planes.

Start-Stop System Solenoid Actuator

On-Board Charger (OBC) DC-Link Switch

Use Scenario: 48 V solenoid actuation in mild-hybrid start-stop systems requiring 100 A pulsed current capability.

IC Role / Device Role / Timing Role: High-current pulse switch triggered by microcontroller GPIO; withstands 100 A IDM pulses.

Use Value: 100 A pulsed drain rating and 54 V/ns dv/dt tolerance prevent false triggering during rapid solenoid release.

Use Scenario: Primary-side switching in bidirectional OBC DC-DC stage handling 300–450 V bus with 15 A RMS current.

IC Role / Device Role / Timing Role: Synchronous rectifier in LLC resonant converter; conducts during zero-voltage switching intervals.

Use Value: Fast 78 ns trr and low Q_rr reduce reverse recovery losses and improve light-load efficiency by >2%.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N6F7	60 V V_DS, 220 A I_D, 1.2 mΩ R_DS(on) - lower voltage, higher current, much lower R_DS(on).	Not suitable for 200 V automotive bus applications; limited to 48 V subsystems.	Select only if system bus voltage ≤60 V and ultra-low conduction loss is prioritized over voltage headroom.
IRF4905PBF	P-channel, -55 V V_DS, 74 A I_D, 20 mΩ R_DS(on) - opposite polarity, lower voltage, higher current.	Requires high-side gate drive circuitry; not drop-in compatible for N-channel high-side use.	Use only when P-channel topology is mandated and voltage rating suffices; gate drive complexity increases BOM count.

Compared with STL220N6F7 and IRF4905PBF, AUIRFR4620 uniquely delivers 200 V blocking capability with automotive-grade thermal and avalanche robustness - essential for 12 V/24 V engine bay switching where voltage transients and ambient heat exceed industrial-grade limits.

FAQ

Is AUIRFR4620 suitable for high-frequency PWM applications above 100 kHz?

Yes - with 13.4 ns turn-on delay, 22.4 ns rise time, and 7.9 nC Q_gd, AUIRFR4620 supports clean switching up to 200 kHz in hard-switched topologies. However, gate drive strength ≥2 A peak and optimized PCB layout are required to maintain low EMI and avoid shoot-through in bridge configurations.

What is the maximum allowable case temperature for continuous 24 A operation?

Per the Absolute Maximum Ratings table, continuous 24 A operation is specified only at T_C = 25°C. At T_C = 100°C, the rated continuous current drops to 17 A. To sustain 24 A continuously, the case temperature must remain ≤55°C, verified via thermal simulation using R_θJC = 1.045°C/W and board-mounted conditions.

Does AUIRFR4620 require a gate resistor for automotive ESD protection?

No - the device itself does not integrate ESD protection; however, a 10–22 Ω series gate resistor is recommended to dampen ringing and limit peak gate current during fast edge transitions. External TVS diodes (e.g., SMAJ15A) between gate and source are advised for ISO 10605-compliant ESD immunity in vehicle harness interfaces.

Can AUIRFR4620 replace IRFR4620 in existing designs?

Yes - AUIRFR4620 is the automotive-qualified version of IRFR4620, sharing identical pinout, electrical specs, and package. Key differences include AEC-Q101 qualification, enhanced process control, and tighter parametric screening. No layout or firmware changes are needed, but qualification documentation must be updated for automotive production releases.
