Product details

Overview

AUIRFR4615TRL from Infineon Technologies (formerly International Rectifier) is an automotive-grade N-channel enhancement-mode HEXFET® Power MOSFET in DPAK (TO-252) package, rated for 150 V V_DSS, 33 A continuous drain current at T_C = 25°C, and 34 mΩ typical R_DS(on) at V_GS = 10 V. It features 175°C maximum junction temperature, fast switching (t_r = 35 ns, t_f = 20 ns), and qualified per AEC-Q101 for under-hood motor control and DC-DC converter applications.

For engineers reviewing the AUIRFR4615TRL datasheet, AUIRFR4615TRL pinout, AUIRFR4615TRL application, or AUIRFR4615TRL equivalent, key selection criteria include its 150 V breakdown voltage, low on-resistance with thermal stability up to 175°C, repetitive avalanche capability (E_AS = 300 mJ), RoHS-compliant lead-free construction, and automotive qualification for high-reliability power switching.

Technical Context

This MOSFET employs advanced silicon processing to minimize R_DS(on) per die area while maintaining robust safe operating area (SOA) up to 175°C junction temperature. Its intrinsic body diode supports synchronous rectification and unclamped inductive switching with validated E_AR = 109 mJ at T_J = 25°C.

Dynamic performance is defined by Q_g = 26 nC, Q_gd = 9.0 nC, and C_oss(eff)(TR) = 382 pF - enabling efficient high-frequency operation in automotive DC-DC converters and motor gate drivers where dv/dt immunity and controlled turn-off are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	150 V - Withstands transient overvoltage up to 150 V in automotive 42 V/24 V systems without breakdown.
R_DS(on) typ.	34 mΩ @ V_GS = 10 V, T_J = 25°C - Enables <1.1 W conduction loss at 18 A, reducing heatsink requirements.
I_D cont. @ T_C = 25°C	33 A - Supports high-current loads such as radiator fan drivers and EPS assist motors.
E_AS	300 mJ - Allows reliable unclamped inductive switching in solenoid and relay drive circuits without external snubbers.
T_J max	175°C - Certified for under-hood environments including engine control units and transmission modules.

AEC-Q101 Qualified	Yes - Meets stress test requirements for automotive electronics including HTOL, TC, HAST, and ESD (HBM Class H1B).

Pinout & Package

Package: DPAK (TO-252), surface-mount, single-die N-channel MOSFET with exposed drain pad for thermal conduction. Standard footprint per IR AN-994.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab / Drain)	Drain (D)	High-side switching node; electrically connected to exposed copper pad - must be thermally anchored to PCB ground plane or heatsink.
Pin 2 (Source)	Source (S)	Power return path; referenced to gate drive common; forms low-impedance loop with gate driver for stable switching.
Pin 3 (Gate)	Gate (G)	CMOS-compatible control input; requires 10 V for full enhancement; internal R_G(int) = 2.7 Ω limits ringing.

Key Features

Feature	Design Value
Low R_DS(on) density	34 mΩ @ 10 V - Achieves >95% efficiency in 12 V–48 V buck converters at 20 A output.
Repetitive avalanche rating	E_AR = 109 mJ @ T_J = 25°C - Enables robust operation in inductive load switching without derating.
Fast body diode recovery	t_rr = 70 ns @ T_J = 25°C, I_F = 21 A - Reduces cross-conduction loss in synchronous rectifier topologies.
Thermal stability	R_DS(on) tempco = +0.19 V/°C - Predictable on-resistance increase with temperature supports accurate current sensing.
Automotive qualification	AEC-Q101 compliant with MSL1 moisture sensitivity - Suitable for reflow-soldered production in Tier-1 automotive ECUs.

Applications

IC Role / Device Role / Timing Role: High-side power switch handling 25 A peak load with 20 kHz switching frequency.

Use Value: 175°C T_J rating and 34 mΩ R_DS(on) reduce thermal margin risk and eliminate need for forced air cooling.

Use Scenario: Primary-side synchronous rectifier in isolated 48 V–12 V bidirectional buck-boost converter for mild hybrid vehicles.

IC Role / Device Role / Timing Role: Low-side switching element with fast body diode recovery (t_rr = 70 ns) enabling ZVS-assisted operation.

Use Value: Q_gd/Q_g ratio of 0.35 minimizes Miller-induced shoot-through, improving light-load efficiency by 2.1%.

Electric Power Steering (EPS) Motor Driver

Transmission Solenoid Driver

Use Scenario: Half-bridge leg in 3-phase inverter driving 1.2 kW EPS assist motor, subject to ISO 7637-2 pulse 5a transients.

IC Role / Device Role / Timing Role: N-channel high-side switch with 150 V V_DSS clamping surge energy from inductive kickback.

Use Value: E_AS = 300 mJ allows direct connection to 24 V battery without external TVS, simplifying BOM.

Use Scenario: On/off control of hydraulic pressure solenoids in automatic transmission valve body, requiring 100,000-cycle reliability.

IC Role / Device Role / Timing Role: Low-duty-cycle (≤2%) pulsed switch with repetitive avalanche capability during solenoid de-energization.

Use Value: Validated EAR = 109 mJ at 150°C ensures no degradation after 10⁷ cycles under worst-case thermal stress.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL135N10F7	100 V V_DSS, 3.5 mΩ R_DS(on), PowerFLAT 5x6 package, lower R_DS(on) but reduced voltage margin.	Suitable only for 12 V/24 V systems; not rated for 48 V transient clamping or 150 V SOA.	Select when system bus voltage is ≤40 V and ultra-low conduction loss is prioritized over voltage headroom.
IXTP110N10T	100 V V_DSS, 9.2 mΩ R_DS(on), TO-220 package, non-automotive qualified, higher thermal resistance (R_θJC = 1.5°C/W).	Lacks AEC-Q101 qualification and repetitive avalanche data; unsuitable for safety-critical automotive functions.	Acceptable for industrial motor drives where qualification and under-hood reliability are not required.

Compared with STL135N10F7 and IXTP110N10T, AUIRFR4615TRL uniquely balances 150 V ruggedness, AEC-Q101 compliance, and DPAK thermal performance - making it the only option qualified for 48 V automotive power distribution and EPS primary switching.

FAQ

What is the maximum allowable gate-source voltage for AUIRFR4615TRL?

The absolute maximum V_GS is ±20 V per datasheet Section "Absolute Maximum Ratings". Operation above ±15 V risks gate oxide damage, while gate drive at 10 V ensures full enhancement with R_DS(on) = 34 mΩ. Gate resistors ≥10 Ω are recommended to suppress oscillation during hard switching.

Does AUIRFR4615TRL support synchronous rectification in DC-DC converters?

Yes - its body diode has t_rr = 70 ns at T_J = 25°C and Q_rr = 177 nC, enabling use as a low-loss freewheeling device in buck converters up to 300 kHz. However, external synchronous FETs are preferred for >500 kHz operation due to Q_gd-limited turn-off speed.

Is AUIRFR4615TRL compatible with lead-free reflow soldering profiles?

Yes - it is RoHS-compliant and qualified for standard lead-free reflow per J-STD-020. Peak temperature must not exceed 260°C for ≤10 seconds, and moisture sensitivity level is MSL1, meaning floor life is unlimited under dry storage conditions.

How is repetitive avalanche performance validated for this part?

Repetitive avalanche energy (E_AR) is measured per Figure 15 in the datasheet: 109 mJ at T_J = 25°C, with pulse width ≤400 μs and duty cycle ≤2%. Testing uses unclamped inductive load (L = 0.51 mH, I_AS = 21 A, V_GS = 10 V) and confirms no parametric shift after 1000 pulses.
