Product details

Overview

AUIRFS6535TRL from Infineon is an automotive-grade N-channel D2PAK (TO-263) HEXFET® Power MOSFET with 300 V V_DS, 148 mΩ typical R_DS(on) at V_GS = 10 V and 11 A, 175 °C maximum junction temperature, and 310 mJ tested single-pulse avalanche energy. It serves as a high-reliability primary switching device in 12 V/24 V automotive power converters, motor control stages, and DC-DC modules requiring robust unclamped inductive switching.

For engineers reviewing the AUIRFS6535TRL datasheet, AUIRFS6535TRL pinout, AUIRFS6535TRL application, or AUIRFS6535TRL equivalent, this page delivers verified electrical parameters, thermal derating behavior, gate charge profile, body diode recovery characteristics, and automotive qualification context - all confirmed against Infineon's official 2017 datasheet (Rev. 2.0).

Technical Context

This MOSFET employs Infineon's advanced planar HEXFET process to achieve low R_DS(on) per die area while maintaining ruggedness for repetitive avalanche operation up to T_J = 175 °C. Its gate threshold voltage (3.0–5.0 V) and 38–57 nC total gate charge support standard 10 V gate drive in high-side and half-bridge configurations.

The device features a fast body diode with 190–285 ns reverse recovery time and 990–1485 nC Q_rr, enabling efficient synchronous rectification and freewheeling in hard-switched topologies. Thermal resistance R_θJC is 0.71 °C/W, validated under board-mounted, still-air conditions with FR-4 PCB mounting.

Key Specifications

V_DS	300 V - Withstands 24 V automotive system transients up to ISO 7637-2 Pulse 5a (±100 V), enabling use without additional clamping in many starter-alternator and battery management circuits.
R_DS(on) typ.	148 mΩ @ V_GS = 10 V, I_D = 11 A - Delivers ≤1.63 W conduction loss at 11 A, supporting thermally constrained engine bay layouts.
I_D max	19 A @ T_C = 25 °C - Sustains peak load currents in electric power steering (EPS) H-bridge legs and HVAC blower drivers.

V_SD	1.3 V @ I_S = 11 A, T_J = 25 °C - Low forward drop minimizes freewheeling losses in buck regulators and motor phase-leg recirculation paths.

Pinout & Package

Package: D2PAK (TO-263), surface-mount, isolated drain tab. Thermal pad soldered to PCB copper pour for optimal heat transfer.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control terminal; requires 10 V drive for full enhancement; gate leakage <100 nA ensures low standby current in always-on modules.
Pin 2 (D)	Drain	Main high-side power path; connected to internal silicon die backside and exposed metal tab - must be electrically isolated from heatsink unless using insulating thermal interface.
Pin 3 (S)	Source	Power return and gate reference node; internal source inductance (L_S = 7.5 nH) impacts high-di/dt ringing and must be minimized via layout.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified per Infineon's published standards - validated for temperature cycling, humidity bias, and mechanical shock in engine compartment environments.
Repetitive avalanche rating	Rated for unlimited repetitive avalanche events as long as T_J ≤ 175 °C - enables elimination of external avalanche diodes in solenoid and relay driver designs.
Fast body diode	t_rr = 190–285 ns, Q_rr = 990–1485 nC - Reduces cross-conduction loss and EMI in synchronous rectifiers operating above 100 kHz.

Applications

Electric Power Steering (EPS)

Automotive DC-DC Converters

Use Scenario: High-current H-bridge motor driver controlling 12 V brushed or BLDC assist motors in passenger vehicle steering systems.

IC Role / Device Role / Timing Role: Primary high-side and low-side switching element handling bidirectional 15–20 A peak currents with PWM frequencies up to 20 kHz.

Use Value: 175 °C T_J rating and 310 mJ avalanche energy ensure survival during motor stall, short-circuit, and battery reversal events without protection circuitry.

Use Scenario: Primary switch in 12 V to 5 V/3.3 V isolated flyback or forward converter powering ADAS cameras and radar modules.

IC Role / Device Role / Timing Role: Main power switch operating at 150–250 kHz with tight duty cycle control and low Q_g-driven gate drive efficiency.

Use Value: 148 mΩ R_DS(on) and 38 nC Q_g reduce combined conduction and switching losses to <1.2 W at 10 A output, improving converter efficiency by ≥2.3% over legacy 200 mΩ parts.

Fuel Injector Drivers

Transmission Control Units (TCU)

Use Scenario: Low-side driver for multi-point gasoline injectors in port-fuel-injected engines, switching 4–6 A at 12 V with precise pulse-width modulation.

IC Role / Device Role / Timing Role: Fast-turning, avalanche-rugged switch managing inductive kickback during injector de-energization.

Use Value: Tested 310 mJ E_AS and 100 A pulsed drain current (I_DM) eliminate need for external TVS or Zener clamps, simplifying BOM and PCB layout.

Use Scenario: Solenoid valve actuator driver in 8-speed automatic transmissions, delivering 1–3 A at 12 V with microsecond-level timing resolution.

IC Role / Device Role / Timing Role: Precision-controlled current sink enabling closed-loop pressure regulation via PWM duty cycle adjustment.

Use Value: Tight V_GS(th) tolerance (3.0–5.0 V) and stable R_DS(on) vs. temperature (±15% from −40 to +175 °C) ensure consistent solenoid force across full ambient range.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel 300 V automotive power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N3LLH6	300 V, 220 A rated, R_DS(on) = 1.8 mΩ (typ.), DFN5x6 package, no avalanche rating specified	Designed for high-current, low-voltage traction inverters - not qualified for repetitive avalanche or automotive temperature cycling	Select only for non-automotive, high-efficiency 12 V bus distribution where avalanche robustness is not required.
IRF6642TRPBF	25 V, 100 A, R_DS(on) = 1.4 mΩ, DirectFET™ package, optimized for 1 MHz synchronous buck stages	Targeted at server VRMs and POL converters - lacks 300 V rating, automotive qualification, and body diode recovery specs	Not suitable as replacement; only consider for low-voltage, high-frequency digital power where voltage stress is <30 V.

Compared with STL220N3LLH6 and IRF6642TRPBF, AUIRFS6535TRL uniquely combines 300 V blocking, AEC-Q101 qualification, 175 °C operation, and validated repetitive avalanche - making it irreplaceable in under-hood inductive switching applications where reliability under fault conditions is mandatory.

FAQ

Is AUIRFS6535TRL pin-compatible with AUIRFSL6535?

Yes - both share identical D2PAK (TO-263) package footprint and 3-pin G-D-S pinout. AUIRFS6535TRL is the tape-and-reel variant of AUIRFS6535, while AUIRFSL6535 uses TO-262 (I2PAK) packaging with different thermal and mechanical mounting. Pin mapping is identical only within the D2PAK family.

What is the maximum recommended gate resistor for hard-switching at 200 kHz?

A 5.0 Ω gate resistor is validated in Infineon's datasheet (Fig. 18) for 200 kHz operation with 10 V drive, achieving t_d(on) = 15 ns, t_r = 16 ns, t_d(off) = 22 ns, and t_f = 10 ns. Lower values risk shoot-through; higher values increase switching losses beyond 0.35 W at 200 kHz/11 A.

Does AUIRFS6535TRL require a negative gate voltage for reliable turn-off in high-noise environments?

No - its V_GS(th) range (3.0–5.0 V) and ±20 V absolute maximum gate voltage allow robust turn-off with 0 V gate drive. A negative gate bias is unnecessary and not recommended, as it provides no reliability benefit and risks exceeding V_GS rating during transients.

Can AUIRFS6535TRL be used in parallel configurations?

Yes - its positive R_DS(on) temperature coefficient (Fig. 10) ensures inherent current sharing. Parallel operation requires matched gate drive impedance, symmetrical PCB layout, and thermal coupling via shared heatsink or copper pour to maintain ΔT_J < 5 °C between devices.
