Product details
Overview
AUIRFR4620TRL from Infineon is an automotive-qualified N-channel D-Pak (TO-252AA) HEXFET® Power MOSFET with 200V V(BR)DSS, 64mΩ typ. RDS(on) at VGS = 10V and ID = 15A, 175°C maximum junction temperature, and 100A pulsed drain current. It serves as a high-efficiency main or synchronous rectifier switch in 12V/24V automotive power conversion systems including DC-DC converters and motor drivers.
For engineers reviewing the AUIRFR4620TRL datasheet, AUIRFR4620TRL pinout, AUIRFR4620TRL application, or AUIRFR4620TRL equivalent, key selection criteria include its 175°C thermal rating, 54 V/ns diode recovery dv/dt capability, repetitive avalanche energy support up to TJmax, and validated performance under automotive transient load conditions per AEC-Q101.
Technical Context
This MOSFET employs Infineon's advanced planar HEXFET process to achieve ultra-low on-resistance per die area while maintaining robust dynamic dV/dT immunity and fast switching (td(on) = 13.4 ns, tr = 22.4 ns). Its body diode supports high di/dt (up to 634 A/µs) and exhibits low Qrr (294 nC at TJ = 25°C) for reduced turn-off losses in hard-switched topologies.
The device features a thermally optimized D-Pak package with RθJC = 1.045°C/W, enabling high-power operation with case-mounted heatsinking. Repetitive avalanche is explicitly rated (IAR, EAR), and SOA curves confirm safe operation up to 100A pulsed drain current at TC = 25°C within defined pulse width and duty cycle limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 200 V - Withstands 200V drain-source blocking voltage before breakdown, suitable for 12V/24V automotive bus applications with ISO 7637-2 pulse suppression margin. |
| RDS(on) typ. | 64 mΩ @ VGS = 10V, ID = 15A - Enables <1W conduction loss at 15A continuous, critical for thermally constrained engine bay modules. |
| ID @ TC = 25°C | 24 A - Continuous drain current rating under ideal heatsink conditions, defining maximum steady-state power delivery capability. |
| TJ max | +175°C - Junction temperature limit enabling reliable operation in under-hood environments without derating below ambient extremes. |
| Qg / Qgd | 25 nC / 7.9 nC - Low total and gate-drain charge reduce driver power requirements and improve switching efficiency in high-frequency (>100 kHz) converters. |
| dv/dt (diode) | 54 V/ns - High diode recovery dv/dt rating prevents false turn-on during commutation, essential for synchronous rectification in buck converters. |
| EAS | 113 mJ - Single-pulse avalanche energy rating allows safe clamping of inductive switching transients without external snubbers. |
Pinout & Package
D-Pak (TO-252AA) surface-mount package with exposed drain pad for thermal enhancement and mechanical stability. Standard footprint per Infineon package drawing IR-DP-01, compatible with IPC-7351B density level B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output terminal | Electrically and thermally connected to exposed copper pad; must be soldered to large PCB copper pour or heatsink for RθJC compliance. |
| Gate | Control input | High-impedance MOS gate requiring <2.6Ω internal resistance; driven by dedicated gate driver to minimize ringing and ensure clean 10V switching. |
| Source | Reference node for gate drive and current sensing | Common return path for load current and gate drive loop; layout must minimize inductance to suppress VGS oscillation during fast switching. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 qualified with full traceability, supporting zero-defect reliability targets in safety-critical powertrain and chassis systems. |
| Repetitive avalanche rating | Rated for unlimited repetitive avalanche events up to TJmax, eliminating need for overvoltage protection circuits in inductive load switching. |
| Ultra-low RDS(on) | 64 mΩ typ. reduces I²R losses by >30% vs. legacy 200V MOSFETs, directly lowering thermal design burden in sealed enclosures. |
| Fast body diode recovery | trr = 78 ns (TJ = 25°C) and Qrr = 294 nC enable efficient synchronous rectification without cross-conduction risk in high-frequency DC-DC stages. |
| Lead-free & RoHS | Halogen-free, Pb-free construction compliant with automotive ELV Directive and JESD204B assembly standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60V V(BR)DSS, 1.2mΩ RDS(on), TO-263 package - lower voltage rating, significantly lower RDS(on), larger package | Not suitable for 200V bus applications; only viable in 48V subsystems where ultra-low loss dominates | Select only if system voltage ≤60V and thermal budget permits TO-263 mounting; not a drop-in replacement |
| IXTP24N20P | 200V V(BR)DSS, 90mΩ RDS(on), TO-220 package - same voltage, higher on-resistance, through-hole mounting | Lacks AEC-Q101 qualification; no repetitive avalanche rating; unsuitable for under-hood vibration or thermal cycling | Acceptable only in non-automotive industrial designs with relaxed reliability and thermal requirements |
Compared with STL220N6F7 and IXTP24N20P, AUIRFR4620TRL uniquely combines AEC-Q101 qualification, 200V rating, 64mΩ on-resistance, and repetitive avalanche capability in a surface-mount D-Pak - making it the sole option for thermally demanding, safety-critical 12V/24V automotive power stages.

FAQ
Is AUIRFR4620TRL pin-compatible with standard D-Pak MOSFETs?
Yes - AUIRFR4620TRL uses the industry-standard D-Pak (TO-252AA) footprint with Drain-Source-Gate pin order (Tab-Source-Gate when viewed from top marking side). Its mechanical dimensions and solder pad layout match JEDEC MO-238, enabling direct PCB replacement for other D-Pak 200V N-channel MOSFETs with identical pinout.
What is the maximum recommended gate drive voltage?
The absolute maximum gate-to-source voltage is ±20V, but Infineon specifies optimal switching performance at VGS = 10V. Driving above 12V yields diminishing RDS(on) improvement while increasing gate oxide stress and risk of overvoltage damage during transients - 10V is the recommended nominal gate drive level.
Does AUIRFR4620TRL require a gate resistor for automotive applications?
Yes - a series gate resistor (typically 5–15Ω) is required to dampen parasitic oscillation, control dv/dt during switching, and limit peak gate current from drivers. Without it, ringing can exceed VGS(max) or cause shoot-through in half-bridge configurations, especially under high di/dt load conditions common in automotive motors.
Can AUIRFR4620TRL be used in parallel configurations?
Yes - its positive RDS(on) temperature coefficient (0.23 V/°C) enables inherent current sharing when paralleled. However, layout symmetry (matched gate and source inductance), individual gate resistors, and thermal coupling via shared heatsink are mandatory to ensure balanced current distribution and avoid thermal runaway.
