Product details

Overview

IPP120N08S404AKSA1 from Infineon Technologies is an AEC-Q101-qualified N-channel enhancement-mode OptiMOS™-T2 power MOSFET in PG-TO220-3-1 package, rated for 80 V V_DS, 4.1 mΩ max R_DS(on) at V_GS = 10 V and I_D = 100 A, with 175 °C maximum junction temperature. It delivers high-current switching in automotive DC-DC converters, motor control inverters, and on-board chargers.

For engineers reviewing the IPP120N08S404AKSA1 datasheet, IPP120N08S404AKSA1 pinout, IPP120N08S404AKSA1 application, or IPP120N08S404AKSA1 equivalent, key selection criteria include R_DS(on) stability over temperature, avalanche ruggedness (E_AS = 310 mJ), gate charge profile (Q_g = 70–95 nC), and thermal resistance (R_thJC = 0.84 K/W).

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low conduction and switching losses in high-duty-cycle automotive power stages. Its gate threshold voltage (V_GS(th) = 2.0–4.0 V) ensures robust noise immunity while enabling direct drive from standard 3.3 V/5 V logic controllers.

The integrated body diode supports synchronous rectification and freewheeling operation with t_rr = 70 ns and Q_rr = 130 nC at T_j = 25 °C, and exhibits stable R_DS(on) temperature coefficient (α ≈ 0.4) up to 175 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	80 V - Maximum drain-source blocking voltage for 12 V/24 V automotive systems with transient margin.
R_DS(on) max	4.1 mΩ @ V_GS = 10 V, I_D = 100 A - Enables <1.2 W conduction loss at 120 A continuous current.
I_D cont	120 A @ T_C = 25 °C - Supported by TO-220 package with copper tab and low R_thJC = 0.84 K/W.
E_AS	310 mJ @ I_D = 60 A - Confirmed single-pulse avalanche energy rating for inductive load turn-off reliability.
Q_g	70–95 nC - Defines gate driver power requirement and switching speed trade-off in hard-switched topologies.
t_r/t_f	10 ns / 35 ns - Fast edge rates support >100 kHz PWM operation with minimized switching loss.
V_GS(th)	2.0–4.0 V - Ensures clean turn-on above typical microcontroller GPIO noise floor.

Pinout & Package

IPP120N08S404AKSA1 uses the PG-TO220-3-1 package: insulated plastic case with three leads, metal tab (drain) electrically connected to pin 2, and standard through-hole mounting footprint.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to ground or current-sense shunt for feedback control.
Pin 2 (Drain)	Drain terminal	High-current power path; electrically tied to metal tab for thermal conduction and EMI shielding.
Pin 3 (Gate)	Control input	High-impedance MOS gate requiring <100 nA leakage; sensitive to ESD and layout-induced ringing.

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive powertrain and chassis applications per stress test requirements.
175 °C operating temperature	Enables placement near heat sources (e.g., inverter modules) without derating in under-hood environments.
100% avalanche tested	Each unit undergoes single-pulse avalanche stress verification-no screening failure rate.
MSL1 reflow rating	Compatible with lead-free reflow profiles up to 260 °C peak, supporting automated PCB assembly.
OptiMOS™-T2 trench architecture	Reduces R_DS(on) × Q_g figure-of-merit by ~25% vs. prior generation for improved efficiency in 48 V systems.

Applications

Automotive On-Board Charger (OBC)

48 V Mild Hybrid DC-DC Converter

Use Scenario: Bidirectional power conversion between 400 V traction battery and 48 V auxiliary bus during regenerative braking and start-stop cycles.

IC Role / Device Role / Timing Role: High-side switch in interleaved buck-boost stage handling 10–15 kW continuous power.

Use Value: Low R_DS(on) minimizes conduction loss at 120 A; avalanche rating ensures safe turn-off during bus fault transients.

Use Scenario: Step-down conversion from 48 V rail to 12 V for ADAS sensors, infotainment, and lighting loads.

IC Role / Device Role / Timing Role: Primary-side synchronous rectifier in phase-shifted full-bridge topology.

Use Value: Fast t_r/t_f enables >200 kHz switching, reducing magnetics size; low Q_g eases gate driver design.

Electric Power Steering (EPS) Inverter

Commercial Vehicle HVAC Blower Drive

Use Scenario: Three-phase inverter supplying torque assist to steering column via 300–500 W BLDC motor.

IC Role / Device Role / Timing Role: Low-side switch in 6-pack half-bridge configuration with space-constrained heatsink.

Use Value: R_thJC = 0.84 K/W allows direct mounting to aluminum housing; 175 °C rating avoids thermal shutdown during peak assist events.

Use Scenario: High-reliability blower motor control in refrigerated truck cabins exposed to wide ambient (-40 to +85 °C).

IC Role / Device Role / Timing Role: Single-ended switch in PWM-controlled flyback or buck-derived supply.

Use Value: AEC-Q101 qualification ensures long-term reliability; 100% avalanche test prevents field failure from inductive kickback.

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
IPP120N08N3-05	R_DS(on) = 3.5 mΩ max (lower), but V_DS = 75 V and non-AEC-Q101 qualified.	Suitable for industrial 48 V supplies where automotive qualification is not required.	Select when higher efficiency outweighs automotive compliance and transient voltage margin.
IPB120N08S4-04	Identical die, PG-TO263-3-2 package; R_thJC = 0.84 K/W same, but surface-mount compatible.	Preferred for automated SMT production and compact board layouts with thermal pads.	Select for volume PCB assembly where reflow compatibility and smaller footprint are critical.

Compared with IPP120N08S404AKSA1, IPP120N08N3-05 trades voltage margin for lower R_DS(on), while IPB120N08S4-04 retains identical electrical specs but shifts to SMD packaging-enabling either cost-optimized industrial use or high-density automotive PCB integration.

FAQ

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

The maximum continuous drain current is 108 A at T_C = 100 °C and V_GS = 10 V, limited by thermal resistance and bondwire capacity-not by silicon channel capability. This rating assumes proper heatsinking and airflow per Infineon's thermal test conditions (FR4 PCB with 6 cm² copper area).

Does IPP120N08S404AKSA1 include an integrated Schottky diode?

No-it features a monolithic parasitic body diode inherent to vertical N-channel MOSFET structure. That diode has V_SD = 0.9–1.3 V at I_F = 100 A and t_rr = 70 ns, but it is not a discrete Schottky; external Schottky diodes may be added for improved reverse recovery in critical synchronous rectifier designs.

Is the gate oxide rated for 20 V absolute maximum, and can it tolerate negative gate voltage?

Yes-V_GS rating is ±20 V, meaning the device tolerates –20 V gate-to-source voltage without oxide damage. However, sustained negative bias below –5 V is not recommended in normal operation due to increased Miller capacitance effects and potential for unintended turn-on during fast dv/dt events.

How does the 100% avalanche testing impact field reliability?

Every unit undergoes single-pulse avalanche stress at I_AS = 99 A and E_AS = 310 mJ-verifying robustness against inductive switching faults. This eliminates latent defects and correlates strongly with long-term reliability in motor drive and converter applications where unclamped inductive switching occurs.
