Product details

Overview

AUIRFP4568-E from Infineon is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in TO-247AC package, rated for 150 V V_DS, 4.8 mΩ typical R_DS(on) at 10 V V_GS, and 171 A continuous drain current at T_C = 25°C. It operates up to 175°C junction temperature and supports repetitive avalanche, enabling robust high-current switching in engine control units, DC-DC converters, and motor drives.

For engineers reviewing the AUIRFP4568-E datasheet, AUIRFP4568-E pinout, AUIRFP4568-E application, or AUIRFP4568-E equivalent, key selection criteria include its 175°C thermal rating, 18.5 V/ns di/dt-rated body diode recovery, 151 nC total gate charge, and automotive qualification per AEC-Q101 - critical for under-hood power stage reliability.

Technical Context

This MOSFET uses advanced planar silicon processing to achieve ultra-low on-resistance per die area while maintaining rugged unclamped inductive switching capability. Its dynamic dv/dt rating (18.5 V/ns) and 763 mJ single-pulse avalanche energy reflect optimized body diode and channel design for fast, thermally stable operation in hard-switched topologies.

The device features a 1.0 Ω internal gate resistance, 10470 pF input capacitance, and 96 nC gate-to-source sync charge (Q_g–Q_gd), supporting efficient gate drive with minimal Miller-induced oscillation. Thermal resistance R_θJC is 0.29 °C/W, enabling high-power dissipation when mounted to heatsinks with greased interface.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	150 V - Maximum blocking voltage for 12 V/48 V automotive battery systems with transient margin.
R_DS(on) typ.	4.8 mΩ at V_GS = 10 V, I_D = 103 A - Enables <1 W conduction loss at 100 A, reducing heatsink requirements.
I_D cont. @ T_C=25°C	171 A - Supports high-current motor phase legs and starter solenoid drivers without parallel devices.
E_AS	763 mJ - Single-pulse avalanche energy limit ensures safe operation during inductive turn-off faults.
Q_g	151 nC max - Determines gate driver current demand; requires ≥1.5 A peak drive for 100 ns switching transitions.
T_J max	+175°C - Enables placement near hot zones (e.g., exhaust manifolds, inverters) without derating.
dv/dt rating	18.5 V/ns - Specifies maximum rate of voltage rise across drain-source before parasitic turn-on occurs.

Pinout & Package

TO-247AC package with isolated tab (drain-connected), standard 3-lead vertical mounting configuration. Long-lead variant (AUIRFP4568-E) facilitates through-hole PCB assembly with enhanced mechanical retention.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control electrode	Receives 10 V logic-level drive; 1.0 Ω internal resistance limits ringing but increases gate charge time.
D (Drain)	High-side power terminal	Connected to heatsink tab; electrically tied to drain; requires isolation from chassis ground unless floating topology.
S (Source)	Reference node / return path	Serves as local ground reference for gate drive; carries full load current and source-diode reverse recovery current.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for engine control, transmission, and ADAS power stages with full traceability.
Repetitive avalanche rating	Supported up to T_Jmax; enables reliable operation in unclamped inductive switching without external snubbers.
Ultra-low R_DS(on)	4.8 mΩ typ. reduces conduction losses by >30% vs. legacy 150 V MOSFETs, improving system efficiency in 48 V mild-hybrid systems.
175°C operating temperature	Allows direct mounting on high-temperature modules (e.g., inverter stacks) without thermal derating penalties.
Fast switching performance	27 ns turn-on delay + 119 ns rise time enables >100 kHz PWM in traction inverters with low switching loss trade-off.

Applications

IC Role / Device Role / Timing Role: High-side switch in phase-shifted full-bridge topology; handles 103 A RMS current with <5 mΩ conduction loss.

Use Value: 4.8 mΩ R_DS(on) cuts conduction loss by 2.1 W vs. 6.5 mΩ alternatives, directly increasing conversion efficiency from 94.2% to 94.8% at 5 kW.

Electric Power Steering (EPS) Motor Phase Leg

On-Board Charger (OBC) AC-DC Front-End

Use Scenario: Low-side switch in three-phase inverter driving 3 kW brushless motor; subjected to frequent short-circuit events and thermal cycling.

IC Role / Device Role / Timing Role: Current-handling switch with integrated body diode conducting regenerative braking current; must survive repetitive avalanche pulses.

Use Value: 763 mJ E_AS and 684 A pulsed drain current allow fault-tolerant operation during motor stall without external protection circuitry.

Use Scenario: PFC boost switch in 6.6 kW OBC handling 230 V AC input with high line-frequency ripple and harmonic content.

Use Value: 151 nC Q_g enables use of cost-effective 2 A gate drivers; 10470 pF C_iss minimizes Miller feedback during high dv/dt transitions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current 150 V power switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW90NF15	R_DS(on) = 5.5 mΩ typ., Q_g = 140 nC, T_Jmax = 175°C, non-AEC-Q101	Lacks automotive qualification; suitable for industrial motor drives but not safety-critical vehicle systems.	Select only for non-automotive designs where AEC-Q101 is not mandated.
IXFH180N15T2	R_DS(on) = 4.2 mΩ typ., Q_g = 185 nC, T_Jmax = 175°C, AEC-Q101 qualified	Lower R_DS(on) improves conduction loss but higher Q_g increases gate drive loss and EMI risk.	Prefer when minimizing conduction loss dominates over switching loss and drive complexity.

Compared with STW90NF15 and IXFH180N15T2, AUIRFP4568-E delivers optimal balance: AEC-Q101 compliance, 4.8 mΩ R_DS(on), and moderate 151 nC Q_g, making it ideal for production automotive power stages requiring validated reliability and thermal headroom.

FAQ

What is the gate threshold voltage range for AUIRFP4568-E?

The gate threshold voltage (V_GS(th)) is specified from 3.0 V to 5.0 V at I_D = 250 µA and V_DS = V_GS. This range ensures reliable turn-on with standard 5 V or 10 V gate drivers while maintaining noise immunity against spurious signals in noisy automotive environments.

Can AUIRFP4568-E be used in synchronous rectification topologies?

Yes - its low 4.8 mΩ R_DS(on), fast 110 ns body diode reverse recovery time, and 1.3 V forward voltage at 103 A make it suitable for high-efficiency synchronous rectification in DC-DC converters, provided gate drive timing avoids shoot-through and accounts for Q_rr = 515 nC at 25°C.

Is the TO-247AC package electrically isolated?

No - the TO-247AC package has an electrically connected metal tab tied to the drain terminal. Electrical isolation from the heatsink requires insulating hardware (e.g., silicone pads, ceramic washers) and proper creepage/clearance layout per ISO 26262 functional safety requirements.

What is the maximum allowable case temperature for continuous operation?

The maximum continuous case temperature is 175°C, matching the rated junction temperature. Derating begins above 25°C ambient per the linear derating factor of 3.45 W/°C, and power dissipation must remain within the SOA curve limits shown in Figure 8 of the datasheet.
