Product details

Overview

IPP120N06S402AKSA1 from Infineon Technologies is a 60 V, 120 A N-channel enhancement-mode MOSFET in PG-TO220-3-1 package, AEC-qualified for automotive powertrain and body electronics, with R_DS(on) max of 2.4 mΩ at V_GS = 10 V and 100% single-pulse avalanche tested to 560 mJ.

For engineers reviewing the IPP120N06S402AKSA1 datasheet, IPP120N06S402AKSA1 pinout, IPP120N06S402AKSA1 application, or IPP120N06S402AKSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.8 K/W), gate charge total (150–195 nC), reverse recovery charge (170 nC), and operation up to 175 °C ambient.

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in high-current DC-DC converters and motor control inverters. Its 2.4 mΩ R_DS(on) enables efficient 12 V/24 V automotive battery-switching applications at continuous 120 A drain current.

The MOSFET integrates a robust body diode with 190 ns reverse recovery time and 170 nC Q_rr, supporting synchronous rectification and freewheeling in hard-switched topologies. Thermal design is enabled by MSL1 reflow compatibility and 0.8 K/W R_thJC, allowing direct heatsink mounting without thermal interface material degradation concerns.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 48 V nominal automotive systems with 20 % safety margin against transients.
R_DS(on) max	2.4 mΩ @ V_GS = 10 V, I_D = 100 A - enables <1.2 W conduction loss at 120 A, reducing heatsink size.
I_D continuous	120 A @ T_C = 25 °C - rated for high-current load switching in starter relays and battery disconnect units.
E_AS	560 mJ @ I_D = 60 A - withstands inductive energy spikes in solenoid and motor drive circuits without failure.
Q_g total	150–195 nC - determines gate driver power requirement; compatible with standard 2 A peak drivers at 100 kHz switching.
t_r/t_f	5 ns / 10 ns - enables fast switching with minimal overlap loss in half-bridge configurations.
T_j max	175 °C - allows operation in under-hood environments without derating below 125 °C ambient.

Pinout & Package

IPP120N06S402AKSA1 uses the PG-TO220-3-1 package: insulated case, vertical lead frame, 3-terminal through-hole mounting with drain-connected tab for direct heatsinking. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives 10 V logic-level signal; requires ≤195 nC charge to fully enhance; sensitive to ESD (±20 V rating).
Pin 2 (Drain)	High-side power terminal	Internally connected to metal tab; must be electrically isolated from heatsink unless system ground-referenced.
Pin 3 (Source)	Reference node	Serves as return path for 120 A load current; defines local ground for gate drive loop; low-inductance layout critical.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive powertrain use per stress test requirements including temperature cycling, HTRB, and UIS.
100% avalanche tested	Each unit passes single-pulse avalanche stress at 560 mJ, ensuring reliability in inductive load switching.
MSL1 reflow rating	Withstands peak solder temperatures up to 260 °C, enabling compatibility with standard lead-free PCB assembly processes.
Green product (RoHS)	Meets EU Directive 2011/65/EU with no restricted substances above threshold limits; halogen-free epoxy molding compound.
Optimized body diode	Q_rr = 170 nC and t_rr = 190 ns enable reduced switching loss in freewheeling paths versus standard MOSFETs.

Applications

Automotive Starter Relay

12 V Battery Disconnect Unit

Use Scenario: High-current contactor replacement in 12 V starter motor circuits, handling cranking surges up to 480 A pulse.

IC Role / Device Role / Timing Role: Main power switch controlling battery-to-starter connection; operates in on/off mode with <10 µs turn-on delay.

Use Value: Eliminates mechanical relay wear and bounce; 2.4 mΩ R_DS(on) reduces voltage drop to <0.3 V at 120 A, preserving cranking torque.

Use Scenario: Isolation switch between vehicle battery and auxiliary loads during sleep mode or fault conditions.

IC Role / Device Role / Timing Role: Bidirectional blocking element with integrated body diode for reverse polarity protection and load dump clamping.

Use Value: Supports 120 A continuous and 480 A pulsed current while maintaining <1.5 W conduction loss; 175 °C rating ensures under-hood reliability.

DC-DC Converter Primary Switch

Electric Power Steering (EPS) Inverter

Use Scenario: High-efficiency buck converter stage stepping down 48 V to 12 V for ADAS ECUs in mild hybrid vehicles.

IC Role / Device Role / Timing Role: Synchronous rectifier switch operating at 200–500 kHz with gate plateau voltage of 5.2 V.

Use Value: Low Q_gd/Q_gs ratio (≈0.3) minimizes Miller-induced shoot-through risk; 150–195 nC Q_g enables precise PWM timing control.

Use Scenario: Half-bridge leg in 3-phase inverter driving 300–500 W brushless DC motor in steering column actuator.

IC Role / Device Role / Timing Role: Low-side switching element with fast 10 ns fall time and 190 ns diode t_rr for clean commutation.

Use Value: Avalanche ruggedness prevents failure during motor phase reversal transients; 0.8 K/W R_thJC enables compact heatsink integration within EPS housing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP120N06N3G	R_DS(on) = 1.8 mΩ (lower), but 150 °C T_j max (vs. 175 °C); no AEC qualification.	Preferred for industrial SMPS where higher temperature rating is not required.	Select when lower conduction loss outweighs automotive qualification and extended temperature range.
IPB120N06S402AKSA1	Same die, PG-TO263-3-2 package; identical R_DS(on), Q_g, and avalanche rating.	Used in surface-mount designs requiring automated assembly and higher power density.	Choose for SMT-based automotive modules where board space and reflow compatibility are prioritized over through-hole serviceability.

Compared with IPP120N06S402AKSA1, IPP120N06N3G trades temperature capability and automotive qualification for lower R_DS(on), while IPB120N06S402AKSA1 offers identical electrical performance in an SMD package-making the TO-220 version optimal for serviceable, high-reliability under-hood installations.

FAQ

What is the maximum allowable gate-source voltage for IPP120N06S402AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond this range risks permanent oxide damage. For reliable switching, gate drive should be limited to 10 V for full enhancement, with transient overshoots held below 15 V using clamping diodes or RC snubbers near the gate terminal.

Does IPP120N06S402AKSA1 require a gate resistor, and if so, what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. For 100 kHz switching with a 2 A peak gate driver, a 3.5 Ω resistor is recommended based on typical gate charge (195 nC) and rise/fall time targets. Lower values increase switching speed but raise EMI risk; higher values reduce driver stress but increase conduction loss.

Can IPP120N06S402AKSA1 be used in parallel configurations?

Yes, but only with matched devices and symmetrical PCB layout. The positive temperature coefficient of R_DS(on) (increasing ~0.5 %/°C) enables inherent current sharing. Each paralleled device must have identical gate drive routing, source inductance, and thermal coupling to avoid thermal runaway at >100 A per device.

Is the drain tab of IPP120N06S402AKSA1 electrically isolated from the package mount surface?

No-the drain is directly connected to the metal tab and is not electrically isolated. When mounted to a heatsink, the tab must either be insulated using a mica washer or ceramic pad, or the heatsink must be referenced to the same potential as the drain circuit to prevent shorting. This is confirmed by the PG-TO220-3-1 mechanical drawing and thermal test setup in the datasheet.
