Product details

Overview

IPI120N06S402AKSA2 from Infineon Technologies is a 60 V, 120 A N-channel enhancement-mode MOSFET in PG-TO262-3-1 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 IPI120N06S402AKSA2 datasheet, IPI120N06S402AKSA2 pinout, IPI120N06S402AKSA2 application, or IPI120N06S402AKSA2 equivalent, key selection factors include its 175 °C operating temperature rating, MSL1 reflow compatibility, integrated body diode with 190 ns t_rr, and thermal resistance R_thJC of 0.8 K/W for high-power motor control and DC-DC converter designs.

Technical Context

This OptiMOS®-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V and 24 V automotive systems. Its gate threshold voltage (2.0–4.0 V) enables robust drive with standard 5 V or 10 V logic-level controllers, while the 150–195 nC total gate charge supports efficient high-frequency PWM operation up to 100 kHz.

The MOSFET integrates a fast-recovery body diode (t_rr = 190 ns, Q_rr = 170 nC) and exhibits stable R_DS(on) over temperature (2.0–2.4 mΩ at 25 °C, rising to ~3.5 mΩ at 175 °C), enabling reliable performance in engine control units and electric power steering modules without external freewheeling diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - Supports 48 V nominal battery systems with 20 % overvoltage margin for load-dump 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 requirements.
I_D continuous	120 A @ T_C = 25 °C - Rated for sustained high-current operation in power distribution modules.
E_AS	560 mJ @ I_D = 60 A - Withstands repetitive inductive switching energy without failure in motor drives.
t_rr	190 ns @ V_R = 30 V, I_F = 50 A - Minimizes reverse recovery loss and EMI in synchronous rectification topologies.
R_thJC	0.8 K/W - Allows direct thermal coupling to chassis or heatsink for compact thermal design in space-constrained ECUs.
Q_g	150–195 nC - Matches standard gate drivers (e.g., 1EDN7512B) for clean 10–50 ns switching transitions.

Pinout & Package

PG-TO262-3-1 package: isolated tab (drain), 3-pin through-hole outline with drain-connected metal tab for direct thermal mounting. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning

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
IPP120N06S4-02	Same die, PG-TO220-3-1 package; R_thJA = 62 K/W (vs. 40 K/W for SMD variants); no isolated tab.	Better suited for prototyping and low-volume manual assembly; limited thermal performance in high-power production modules.	Select when cost-sensitive, lower-current (<80 A) applications allow larger heatsinks.
IPB120N06S4-02	Same die, PG-TO263-3-2 surface-mount package; identical R_DS(on) and E_AS; requires reflow-compatible PCB layout.	Enables automated assembly and higher board density; unsuitable for through-hole or chassis-mounted thermal paths.	Select for high-volume automotive PCBs where automated placement and thermal pad routing are available.

Compared with IPP120N06S4-02 and IPB120N06S4-02, the IPI120N06S402AKSA2 offers optimal balance of through-hole manufacturability, thermal performance (R_thJC = 0.8 K/W), and mechanical robustness for under-hood power modules requiring direct heatsink attachment.

FAQ

What is the maximum junction temperature and how is it validated?

The IPI120N06S402AKSA2 is rated for continuous operation up to 175 °C junction temperature, verified per AEC-Q101 stress test conditions including high-temperature operating life (HTOL) at 175 °C for 1000 hours with electrical parameter monitoring. Thermal derating curves in the datasheet define safe operating area limits above 25 °C case temperature.

Does this MOSFET require a gate resistor, and what value is recommended?

Yes - a gate resistor is required to control dV/dt and prevent oscillation. For 100 kHz PWM at 120 A, a 3.3 Ω to 5.6 Ω non-inductive resistor is recommended based on gate charge (150–195 nC) and typical driver output impedance. Lower values improve switching speed but increase EMI risk; higher values reduce shoot-through risk in half-bridge configurations.

Is the body diode suitable for synchronous rectification in DC-DC converters?

Yes - the integrated body diode has t_rr = 190 ns and Q_rr = 170 nC at 50 A, enabling use in synchronous buck topologies up to 100 kHz. However, for >200 kHz operation or ultra-low-loss designs, an external Schottky diode may still be preferred due to lower forward voltage and zero reverse recovery charge.

How does the PG-TO262-3-1 package differ thermally from PG-TO220-3-1?

The PG-TO262-3-1 package features an isolated metal tab and optimized internal bondwire layout, achieving R_thJC = 0.8 K/W - identical to the PG-TO263-3-2 SMD variant and 25 % better than the PG-TO220-3-1's 1.07 K/W. This allows higher continuous current in the same heatsink footprint without requiring thermal interface material rework.
