Product details

Overview

AUIRFR120ZTRL from Infineon is an automotive-grade N-channel D-Pak Power MOSFET with 100 V V_DS, 150 mΩ typical R_DS(on) at V_GS = 10 V, 8.7 A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature-designed for high-reliability engine control, transmission solenoid drivers, and body electronics switching.

For engineers reviewing the AUIRFR120ZTRL datasheet, AUIRFR120ZTRL pinout, AUIRFR120ZTRL application, or AUIRFR120ZTRL equivalent, key selection criteria include its rated repetitive avalanche energy (20 mJ tested), fast switching (t_r = 26 ns, t_f = 23 ns), low gate charge (Q_g = 6.9 nC), and automotive qualification per AEC-Q101.

Technical Context

This MOSFET employs Infineon's HEXFET® process to achieve ultra-low on-resistance per die area while maintaining robust thermal performance. Its 175°C operating junction temperature and validated repetitive avalanche capability (up to I_AR = 12 A, E_AR = 20 mJ at 1% duty cycle) support sustained operation in under-hood environments.

The device features a fast intrinsic body diode (t_rr = 24–36 ns, Q_rr = 23–35 nC) and low output capacitance (C_oss = 41 pF at V_DS = 25 V), enabling efficient hard-switching in DC-DC converters and motor drive half-bridges without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Withstands automotive load-dump transients up to ISO 7637-2 Pulse 5a (120 V peak) with margin.
R_DS(on) typ.	150 mΩ at V_GS = 10 V, I_D = 5.2 A - Enables <1.3 W conduction loss at 8.7 A, reducing heatsink requirements.
I_D cont.	8.7 A at T_C = 25°C - Supports high-current solenoid and lamp loads in 12 V systems without derating.
E_AS tested	20 mJ - 100% production-tested single-pulse avalanche energy ensures robustness against inductive turn-off spikes.
Q_g	6.9 nC - Low gate drive power enables direct MCU GPIO driving or minimal gate driver sizing.
t_r/t_f	26 ns / 23 ns - Reduces switching losses below 100 kHz, suitable for PWM-controlled HVAC actuators.
T_J max	+175°C - Certified for under-hood placement in engine management modules per AEC-Q101.

Pinout & Package

Package: D-Pak (TO-252AA), surface-mount, thermally enhanced with exposed drain pad.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control input	Receives 10 V logic-level signal; threshold voltage 2.0–4.0 V ensures compatibility with 3.3 V/5 V microcontrollers.
D (Drain)	High-side or low-side power path	Internally connected to exposed metal pad; must be soldered to PCB copper pour for thermal conduction (R_θJC = 4.28°C/W).
S (Source)	Reference node / return path	Provides common reference for gate drive and current sensing; internal source inductance (L_S = 7.5 nH) impacts di/dt-induced ringing.

Key Features

Feature	Design Value
Automotive qualification	AEC-Q101 qualified - Validated for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
Repetitive avalanche rating	Tested to 20 mJ single-pulse and rated for repetitive operation - Eliminates need for external clamping in inductive load circuits.
Ultra-low R_DS(on)	150 mΩ typ. - Reduces I²R losses by >30% vs. legacy 200 mΩ automotive MOSFETs at same current.
Fast body diode	t_rr = 24 ns, Q_rr = 23 nC - Minimizes reverse recovery loss in synchronous rectification and freewheeling paths.
Thermal robustness	R_θJA = 50°C/W (PCB mounted) - Enables operation at full current with only 2 oz copper and 1"² thermal pad.

Applications

Engine Control Unit (ECU) Solenoid Driver

Transmission Control Module (TCM) Valve Actuator

Use Scenario: Driving 12 V, 2–5 A fuel injector or idle air control valve in gasoline direct injection systems.

IC Role / Device Role / Timing Role: High-side switch controlling pulsed coil current with 1–10 ms ON time and 10–20 kHz PWM modulation.

Use Value: 175°C rating prevents thermal shutdown during extended idling; 20 mJ avalanche rating absorbs back-EMF without snubber.

Use Scenario: Controlling hydraulic pressure valves in 8-speed automatic transmissions requiring precise 5–15 A current pulses.

IC Role / Device Role / Timing Role: Low-side switch in H-bridge configuration with bidirectional current flow and fast polarity reversal.

Use Value: Low Q_g (6.9 nC) enables <1 µs dead-time control; fast t_r/t_f minimizes shoot-through risk.

Body Control Module (BCM) Lamp Load Switch

Electric Power Steering (EPS) Motor Phase Driver

Use Scenario: Switching halogen headlamps (55 W, ~4.6 A) and fog lamps in centralized lighting control units.

IC Role / Device Role / Timing Role: Single-ended low-side switch with PWM dimming and short-circuit protection feedback via sense-FET.

Use Value: R_DS(on) = 150 mΩ limits self-heating to <3.2 W at full load, avoiding thermal derating in sealed enclosures.

Use Scenario: Half-bridge phase leg in 12 V EPS assist motors delivering up to 30 A peak current per phase.

IC Role / Device Role / Timing Role: High-efficiency power stage switch with integrated body diode conducting freewheeling current during PWM off-time.

Use Value: Low C_oss (41 pF) and fast t_f (23 ns) reduce switching loss to <150 mW at 20 kHz, improving system efficiency by 1.2%.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL105N10F7	100 V, R_DS(on) = 11.5 mΩ (typ.), DFN5x6 package, 120 A pulsed ID	Higher current density but requires multilayer PCB for thermal management; no AEC-Q101 documentation publicly available	Select when board space is constrained and peak current exceeds 10 A; verify qualification status with ST.
ON Semiconductor NTMFS5C670NL	100 V, R_DS(on) = 12.5 mΩ (typ.), SO-8FL package, 175°C TJ, AEC-Q101 qualified	Lower R_DS(on) but 50% higher Q_g (10.5 nC); smaller footprint limits thermal dissipation to 2.5 W	Prefer for compact, low-loss designs where average power <2.5 W; avoid for sustained 8.7 A operation.

Compared with STL105N10F7 and NTMFS5C670NL, AUIRFR120ZTRL offers balanced trade-offs: verified AEC-Q101 compliance, proven 20 mJ avalanche robustness, and D-Pak thermal performance ideal for mid-power (3–8 A) automotive loads without complex layout.

FAQ

Is AUIRFR120ZTRL pin-compatible with AUIRFU120Z?

No. AUIRFR120ZTRL uses the D-Pak (TO-252AA) package with Drain–Source–Gate pin order (D-S-G), while AUIRFU120Z uses the I-Pak (TO-251AA) package with Drain–Gate–Source order (D-G-S). Footprint and thermal pad layout differ; PCB redesign is required for substitution.

What is the maximum recommended gate resistor for PWM switching at 20 kHz?

A 10 Ω gate resistor is recommended for 20 kHz operation. This value balances switching speed (t_r/t_f ≈ 25 ns) and gate drive stability, limiting peak gate current to <1 A while suppressing oscillation from L_S and C_iss interaction.

Does AUIRFR120ZTRL require a negative gate voltage for reliable turn-off in noisy automotive environments?

No. The device has a gate threshold voltage range of 2.0–4.0 V and exhibits no unintended turn-on up to V_GS = +1 V. A 0 V to 10 V gate drive is sufficient; negative bias is unnecessary unless operating near EMI sources exceeding 50 V/ns dv/dt.

Can AUIRFR120ZTRL replace IRFR120Z in existing industrial designs?

Yes, with qualification. AUIRFR120ZTRL shares identical electrical specs and D-Pak footprint with IRFR120Z but adds AEC-Q101 qualification, 175°C rating, and enhanced avalanche testing. Thermal and layout compatibility is maintained; revalidation of surge immunity and lifetime reliability is advised.
