Product details

Overview

AUIRFS3306TRL from Infineon is an automotive-grade N-channel HEXFET® Power MOSFET in D2-Pak (TO-263AB) package, rated for 60V V_DS, 3.3 mΩ typ. R_DS(on) at V_GS = 10V and 75A, with 175°C maximum junction temperature and 120A package-limited continuous drain current. It serves as a high-efficiency main or synchronous rectifier switch in 48V automotive DC-DC converters.

For engineers reviewing the AUIRFS3306TRL datasheet, AUIRFS3306TRL pinout, AUIRFS3306TRL application, or AUIRFS3306TRL equivalent, key selection criteria include its 60V breakdown voltage, ultra-low on-resistance under high-temperature operation, avalanche ruggedness, and automotive qualification per AEC-Q101 standards.

Technical Context

This MOSFET employs Infineon's advanced silicon process to achieve low R_DS(on) density and enhanced thermal robustness. Its 175°C T_J rating enables operation in under-hood environments without derating, while the 184 mJ single-pulse avalanche energy supports unclamped inductive switching in motor drives and starter generators.

Dynamic performance is defined by 85 nC typical total gate charge, 26 nC gate-to-drain charge, and 14 V/ns peak diode recovery dv/dt capability-enabling fast, controlled turn-off in high-frequency synchronous buck stages up to 300 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Withstands 48V system transients up to ISO 7637-2 Pulse 5a (75V/100ms) without clamping.
R_DS(on) typ.	3.3 mΩ @ V_GS = 10V, I_D = 75A - Delivers ≤ 18.9 W conduction loss at 120A, critical for thermal management in compact power modules.
I_D (Package)	120 A @ T_C = 25°C - Determined by bond-wire current limit, not silicon; defines PCB layout copper weight and thermal pad requirements.
E_AS	184 mJ - Enables reliable operation in unclamped inductive switching (e.g., solenoid drivers) without external snubbers.
R_θJC	0.65 °C/W - Allows direct heatsink mounting; 100W dissipation raises case temperature only 65°C above heatsink.
Q_g	85 nC typ. - Requires ≥ 1.5 A peak gate driver current for 50 ns rise time, influencing gate driver IC selection (e.g., 1EDN7512B).
T_J max	+175°C - Supports operation in engine bay locations where ambient exceeds 125°C, eliminating need for remote placement.

Pinout & Package

Supplied in D2-Pak (TO-263AB) package with exposed drain tab for thermal and electrical connection. The three terminals are arranged in G–D–S order (left-to-right when viewed with marking side up and leads facing down).

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control input	Receives 10V logic-level drive; 0.7 Ω internal gate resistance limits ringing but requires low-impedance driver path.
Drain (D)	High-side power node	Exposed metal tab; must be electrically isolated from heatsink unless referenced to same potential (e.g., high-side switch in half-bridge).
Source (S)	Power return / reference	Connected to PCB ground plane; source inductance directly impacts switching loss and dV/dt immunity.

Key Features

Feature	Design Value
Ultra-low R_DS(on)	3.3 mΩ typ. enables >97% efficiency in 48V→12V 100A DC-DC converters at full load.
175°C operating temperature	Eliminates derating in under-hood applications; maintains R_DS(on) < 5.5 mΩ up to T_J = 175°C.
Repetitive avalanche rated	Supports >100,000 cycles of 96A/100µs avalanche pulses without degradation-validated per AN-1005.
Fast body diode recovery	31 ns t_rr at T_J = 25°C reduces cross-conduction loss in synchronous rectification mode.
AEC-Q101 qualified	Passed stress tests including HTGB, HTRB, UHAST, and temperature cycling-certified for safety-critical automotive subsystems.

FAQ

What is the difference between silicon-limited and package-limited current ratings for AUIRFS3306TRL?

The silicon-limited current (160A) is calculated based on thermal limits of the die at 175°C junction temperature, while the package-limited current (120A) reflects physical constraints of the bond wires and lead frame. Designers must use 120A for PCB layout and thermal design, as exceeding it risks wire bond failure even if junction temperature remains within spec.

Can AUIRFS3306TRL be used in parallel configurations?

Yes-its positive R_DS(on) temperature coefficient (0.07 V/°C) ensures inherent current sharing across paralleled devices. However, matched gate drive routing, symmetrical PCB layout, and individual gate resistors (≥2.7 Ω) are required to suppress oscillation and ensure balanced dynamic current distribution during switching transitions.

Is the body diode suitable for synchronous rectification in hard-switched topologies?

Yes-the body diode exhibits 31 ns reverse recovery time and 34 nC Q_rr at 25°C, making it viable for synchronous rectification in 48V buck converters up to 300 kHz. At elevated temperatures (125°C), t_rr increases to 35 ns and Q_rr to 45 nC, requiring careful dead-time optimization to avoid shoot-through.

Does AUIRFS3306TRL require a negative gate voltage for reliable turn-off in high-dV/dt environments?

No-its ±20 V gate rating and 4.0 V maximum V_GS(th) provide sufficient noise margin. However, applying –5 V during turn-off improves immunity to Miller-induced false turn-on in high-side configurations with >10 V/ns dV/dt across the drain-source node, especially when used with discrete gate drivers.
