Infineon Technologies IPP120N04S302AKSA1

Overview

IPP120N04S302AKSA1 from Infineon Technologies is an automotive-grade N-channel enhancement-mode power MOSFET in PG-TO220-3-1 package, rated for 40 V V_DS, 120 A continuous drain current at T_C = 25 °C, and ultra-low 1.65 mΩ typical R_DS(on) at V_GS = 10 V. It is AEC-Q101 qualified, 100% avalanche tested, and used in high-current DC-DC converters and motor control stages in engine management systems.

For engineers reviewing the IPP120N04S302AKSA1 datasheet, IPP120N04S302AKSA1 pinout, IPP120N04S302AKSA1 application, or IPP120N04S302AKSA1 equivalent, key selection criteria include R_DS(on) at 80 A, thermal resistance (R_thJC = 0.5 K/W), avalanche energy (E_AS = 1880 mJ), gate charge profile (Q_g = 160–210 nC), and TO-220 leaded thermal performance under 100 °C case temperature.

Technical Context

This OptiMOS™-T device uses trench-based silicon technology optimized for low conduction loss and fast switching in 12 V automotive systems. Its gate threshold voltage (2.1–4.0 V) enables robust drive with standard 5 V or 10 V logic-level controllers, while its 11,000–14,300 pF input capacitance and 470–710 pF reverse transfer capacitance support predictable turn-on/turn-off timing in synchronous buck topologies.

The integrated body diode exhibits 0.83–1.2 V forward voltage at 80 A and 25 °C, with 70 ns reverse recovery time and 145 nC Q_rr, enabling efficient freewheeling in high-frequency PWM motor drives without external Schottky supplementation.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The absolute maximum junction temperature is +175 °C, and the device is fully specified for continuous operation across this range. Derating curves in the datasheet show that at T_C = 100 °C, the continuous drain current remains 120 A with V_GS ≥ 6 V, confirming thermal stability under sustained high-load conditions typical in under-hood environments.

Is IPP120N04S302AKSA1 suitable for synchronous rectification in a 400 kHz buck converter?

Yes - its 19 ns rise time, 18 ns fall time, and 160–210 nC total gate charge enable clean switching at 400 kHz. The 0.83–1.2 V body diode forward voltage and 70 ns reverse recovery time further support efficient synchronous operation without cross-conduction, provided gate drive strength exceeds 2 A peak.

Does the TO-220 package have an electrically isolated tab?

Yes - the "KSA1" suffix denotes the insulated version: the metal tab is internally isolated from the drain terminal and rated for 2.5 kV AC isolation per IEC 60747-5-2. This eliminates the need for mica washers or silicone pads when mounting directly to grounded heatsinks in automotive ECU enclosures.

How does the 100% avalanche testing impact reliability in solenoid drive applications?

Each unit undergoes UIS stress testing at 80 A with defined L×di/dt, verifying capability to absorb 1880 mJ without parametric shift or failure. In solenoid circuits, this ensures immunity to voltage spikes exceeding 60 V during turn-off, preventing latent degradation or catastrophic failure over 100,000+ actuation cycles in engine valve control.
