Product details

Overview

AUIRF2907Z from Infineon is an automotive-qualified N-channel enhancement-mode HEXFET® Power MOSFET in TO-220AB package, rated for 75V V_DS, 4.5 mΩ R_DS(on) max at V_GS = 10 V and I_D = 75 A, with 175°C maximum junction temperature and repetitive avalanche capability. It delivers high-current switching in engine control units, DC-DC converters, and motor drivers where low conduction loss and thermal robustness are critical.

For engineers reviewing the AUIRF2907Z datasheet, AUIRF2907Z pinout, AUIRF2907Z application, or AUIRF2907Z equivalent, key selection factors include its silicon-limited 170 A continuous drain current at 25°C, 0.50°C/W junction-to-case thermal resistance, fast 140 ns rise time, and validated unclamped inductive switching performance up to T_Jmax.

Technical Context

This MOSFET employs advanced planar silicon processing to achieve ultra-low on-resistance per die area while maintaining ruggedness against repetitive avalanche stress. Its gate threshold voltage (2.0–4.0 V) and 180 S forward transconductance support stable turn-on across automotive temperature ranges.

The device features a body diode with 75 A continuous source current rating, 1.3 V forward voltage at 75 A and 25°C, and 41–61 ns reverse recovery time - enabling efficient synchronous rectification and freewheeling in high-frequency power stages without external diode supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V - Maximum blocking voltage before breakdown; suitable for 48 V automotive systems and 24 V industrial rails.
R_DS(on) max	4.5 mΩ @ V_GS = 10 V, I_D = 75 A - Enables ≤3.4 W conduction loss at 75 A, reducing heatsink requirements.
I_D (Package Limited)	75 A @ T_C = 25°C - Real-world continuous current constrained by TO-220AB package thermal limits.
T_J max	+175°C - Allows operation in under-hood environments without derating below ambient extremes.
E_AS (Tested)	690 mJ - Verified single-pulse avalanche energy at I_AS = 75 A, L = 0.095 mH, confirming robustness in inductive load switching.
Q_g	180–270 nC - Gate charge magnitude directly impacts driver sizing and switching loss in PWM applications above 50 kHz.
R_θJC	0.50°C/W - Enables precise junction temperature estimation from case temperature measurements during thermal design.

Pinout & Package

TO-220AB package with isolated tab (drain-connected), standard through-hole mounting, and 1.1 N·m screw torque rating. Thermal path optimized for direct heatsink interface via flat greased surface.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main high-side current path	Internally connected to metal tab; requires electrical isolation from heatsink unless system ground reference permits.
Source (S)	Power return / reference node	Low-inductance connection point for current sensing and gate drive return; LS = 13 nH contributes to di/dt-induced voltage spikes.
Gate (G)	Control terminal	High-impedance input requiring <20 V absolute max; 180 nC total charge demands ≥2 A peak driver for <100 ns switching transitions.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	3.5 mΩ typical at 75 A enables >98% efficiency in 48 V/75 A DC-DC stages at 100 kHz.
175°C operating junction	Eliminates need for active cooling in space-constrained engine bay modules operating at 125°C ambient.
Repetitive avalanche rated	Validated up to T_Jmax per Fig. 12a–c; supports reliable operation in unclamped inductive loads like fuel injectors and solenoids.
Fast switching (t_r = 140 ns)	Reduces transition losses in high-frequency SMPS designs, enabling smaller magnetics and output capacitors.
Automotive qualification	Complies with AEC-Q101 standards; includes 100% R_DS(on), V_GS(th), and E_AS testing per lot.

Applications

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

IC Role / Device Role / Timing Role: Main power switch operating at 200 kHz with 75 A RMS current and 150 V transient spikes.

Use Value: 4.5 mΩ R_DS(on) limits conduction loss to 25 W at full load; 0.50°C/W R_θJC allows passive heatsinking in compact enclosures.

Electric Power Steering (EPS) Motor Phase Leg

On-Board Charger (OBC) Input Stage Switch

Use Scenario: Half-bridge phase leg driving 3-phase 400 W EPS motor with 150 A peak phase current.

IC Role / Device Role / Timing Role: Low-side switching element handling high di/dt (≥340 A/µs) and body-diode commutation.

Use Value: 75 A continuous source current and 41 ns trr minimize body-diode losses during dead-time conduction; 13 nH LS reduces gate oscillation risk.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	75 V, 2.2 mΩ R_DS(on), 220 A silicon-limited ID, DFN8 5×6 mm package	Surface-mount only; no isolated tab; higher current density but lower avalanche rating (E_AS = 320 mJ)	Preferred for space-constrained PCB layouts where thermal interface uses soldered copper; not suitable for bolt-down heatsinks.
IRFB4115PBF	150 V, 5.8 mΩ R_DS(on), TO-220AB, non-automotive qualified	Higher voltage margin but wider R_DS(on) tolerance (5.8 mΩ vs. 4.5 mΩ max); lacks AEC-Q101 validation and 175°C rating	Acceptable for industrial 48 V systems with ambient <105°C; not approved for safety-critical automotive functions.

Compared with STL220N4F7AG and IRFB4115PBF, AUIRF2907Z uniquely balances automotive qualification, 0.50°C/W thermal resistance, and 690 mJ tested avalanche energy - making it the only choice for under-hood high-reliability switching where mechanical mounting and thermal cycling dominate lifetime constraints.

FAQ

What is the maximum continuous drain current for AUIRF2907Z at 100°C case temperature?

The AUIRF2907Z supports 120 A continuous drain current at T_C = 100°C and V_GS = 10 V, as specified in the Absolute Maximum Ratings table. This reflects silicon-limited current capacity under elevated thermal conditions, distinct from the 75 A package-limited rating at 25°C.

Does AUIRF2907Z require a gate resistor for safe operation?

Yes - a gate resistor (typically 2.5 Ω to 10 Ω) is required to control dV/dt and prevent parasitic oscillation during switching. The datasheet specifies R_G = 2.5 Ω for dynamic characterization (e.g., t_d(off), t_f), and omitting it risks shoot-through in half-bridge configurations due to high C_iss (7500 pF) and fast edge rates.

Can AUIRF2907Z be used in parallel configurations?

Yes - its positive R_DS(on) temperature coefficient (0.069 V/°C) enables inherent current sharing when paralleled. Designers must match gate drive loop inductance and ensure symmetrical PCB layout; the 175°C rating supports balanced thermal distribution across multiple devices in high-power inverters.

Is the TO-220AB package lead-free and RoHS compliant?

Yes - AUIRF2907Z is explicitly marked "Lead-Free, RoHS Compliant" in its official datasheet, with termination finish meeting JEDEC J-STD-609 Class 2A requirements. The soldering temperature rating of 300°C for 10 seconds confirms compatibility with lead-free reflow profiles.
