Product details

Overview

AUIRFR2607Z from Infineon is an automotive-grade N-channel D-Pak Power MOSFET with 75 V V_DS, 17.6 mΩ typ. R_DS(on) at V_GS = 10 V, 42 A package-limited continuous drain current, and 175 °C maximum junction temperature. It serves as a high-efficiency main or synchronous rectifier switch in DC-DC converters and motor control circuits for engine management and body electronics.

For engineers reviewing the AUIRFR2607Z datasheet, AUIRFR2607Z pinout, AUIRFR2607Z application, or AUIRFR2607Z equivalent, key selection criteria include its 1.38 °C/W R_θJC, 96 mJ single-pulse avalanche energy rating, fast switching (t_r = 59 ns, t_f = 28 ns), and automotive qualification per AEC-Q101.

Technical Context

This device uses Infineon's HEXFET® process to achieve ultra-low on-resistance and robust unclamped inductive switching capability. Its gate threshold voltage (2.0–4.0 V) and 34 nC total gate charge support standard 10 V gate drive while maintaining low switching losses in hard-switched topologies.

The integrated body diode exhibits 1.3 V forward voltage at 30 A and 30 ns typical reverse recovery time, enabling efficient freewheeling in buck and half-bridge configurations. Repetitive avalanche operation is permitted up to T_Jmax, validated per Fig. 12a–12b and AN-1005.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	75 V - Withstands transient overvoltage up to 75 V in 12 V automotive systems with load dump protection.
R_DS(on) typ.	17.6 mΩ @ V_GS = 10 V, I_D = 30 A - Enables <1.2 W conduction loss at 42 A, reducing heatsink requirements.
I_D (Package)	42 A @ T_C = 25 °C - Thermal limit set by D-Pak package; derates to 32 A at 100 °C case temperature.
E_AS	96 mJ - Single-pulse avalanche energy tested 100% in production; supports reliable inductive turn-off without snubbers.
t_r/t_f	59 ns / 28 ns - Fast edge rates minimize switching transition time, reducing overlap losses in PWM stages.
R_θJC	1.38 °C/W - Low junction-to-case thermal resistance enables direct mounting to heatsinks or copper planes for high-power density designs.
Q_g	34 nC typ. - Gate drive power requirement of ~340 µC at 10 V enables use with standard gate drivers (e.g., IR2104, UCC27531).

Pinout & Package

Supplied in surface-mount D-Pak (TO-252AA) package with exposed drain pad for thermal and electrical connection. Pin assignment is standardized across Infineon's AUIRFR-series.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Main current path output terminal	Connected to exposed metal tab; must be soldered to large copper pour or heatsink for thermal performance.
Source (S)	Power return and reference node	Low-inductance source connection critical for stable gate drive; internal LS = 7.5 nH.
Gate (G)	Control input for channel conduction	High-impedance MOS gate requiring <20 V absolute max; 34 nC Q_g defines driver sizing.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified for under-hood applications with guaranteed operation from –55 °C to +175 °C.
Repetitive avalanche rating	Validated per Fig. 12a–12b and Fig. 15–16; allows safe operation in unclamped inductive switching without external clamping.
Ultra-low R_DS(on)	17.6 mΩ typ. at 10 V drive reduces conduction loss by >30% vs. legacy 75 V MOSFETs in same package.
Fast body diode	30 ns t_rr, 28 nC Q_rr - Minimizes reverse recovery loss and EMI in synchronous rectification and H-bridge freewheeling.
Lead-free & RoHS	Halogen-free, Pb-free terminations compliant with automotive environmental standards and reflow profiles.

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
STL130N7LF6	75 V, 1.3 mΩ R_DS(on), PowerFLAT 5x6 package, lower R_DS(on) but higher Q_g (65 nC)	Better conduction loss but slower switching; requires stronger gate driver	Select when thermal budget is tighter than drive capability; not drop-in due to different footprint and pinout
IRF3207PbF	75 V, 22 mΩ R_DS(on), TO-220AB package, non-automotive grade, 150 °C T_Jmax	Larger package, no AEC-Q101 qualification, lower avalanche rating (E_AS = 62 mJ)	Select only for non-automotive industrial use where qualification and compactness are not required

Compared with STL130N7LF6 and IRF3207PbF, AUIRFR2607Z delivers optimal balance of automotive qualification, D-Pak compactness, 96 mJ avalanche robustness, and 34 nC gate charge-making it preferred for space-constrained, safety-critical vehicle subsystems where reliability under transient stress is mandatory.

FAQ

What is the maximum continuous drain current for AUIRFR2607Z at 100°C case temperature?

The maximum continuous drain current is 32 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table under "ID @ TC = 100°C Continuous Drain Current, VGS @ 10V (Silicon Limited)." This reflects silicon-limited conduction capability after thermal derating, distinct from the 42 A package-limited rating at 25 °C.

Is AUIRFR2607Z suitable for synchronous rectification in a 48 V automotive DC-DC converter?

Yes. Its 17.6 mΩ R_DS(on), 1.3 V body diode forward voltage, and 30 ns reverse recovery time make it well-suited for low-loss synchronous rectification. The 175 °C junction rating and AEC-Q101 qualification ensure reliability under sustained 48 V bus transients and thermal cycling.

Does AUIRFR2607Z require a gate resistor for stability in hard-switched applications?

A gate resistor is recommended to damp ringing and control dV/dt. Typical values range from 5 Ω to 15 Ω, based on driver capability and layout parasitics. The device's 34 nC Q_g and 14 ns turn-on delay allow predictable timing with standard gate drivers when properly terminated.

Can AUIRFR2607Z replace IRFZ44N in an existing automotive design?

No direct replacement: IRFZ44N is a 55 V, non-automotive TO-220 MOSFET with 28 mΩ R_DS(on) and no AEC-Q101 rating. AUIRFR2607Z offers higher voltage rating (75 V), lower on-resistance, D-Pak footprint, and automotive qualification-but requires PCB redesign and validation of thermal and avalanche margins.
