Infineon Technologies IPP120P04P4L03AKSA1

Overview

IPP120P04P4L03AKSA1 from Infineon Technologies is a P-channel logic-level enhancement-mode MOSFET in PG-TO220-3-1 package, rated for -40 V V_DS, 3.1 mΩ R_DS(on) at V_GS = -10 V and I_D = -100 A, with 175 °C maximum junction temperature and AEC-Q101 qualification. It serves as a high-current load switch in automotive body control modules and industrial DC power distribution systems.

For engineers reviewing the IPP120P04P4L03AKSA1 datasheet, IPP120P04P4L03AKSA1 pinout, IPP120P04P4L03AKSA1 application, or IPP120P04P4L03AKSA1 equivalent, key selection criteria include logic-level gate drive compatibility (V_GS(th) = -1.2 to -2.2 V), low R_DS(on) at 4.5 V, avalanche ruggedness (E_AS = 78 mJ), and thermal resistance (R_thJC = 1.1 K/W).

Technical Context

This device implements a trench-based OptiMOS®-P2 silicon structure optimized for low conduction loss and fast switching in high-side and low-side configurations. Its gate threshold voltage range (-1.2 to -2.2 V) ensures reliable turn-on with standard 3.3 V or 5 V logic drivers, while its 100% avalanche-tested construction supports robust operation under inductive load switching.

The integrated body diode exhibits t_rr = 54 ns and Q_rr = 60 nC at I_F = -50 A and di_F/dt = -100 A/µs, enabling efficient synchronous rectification and freewheeling in buck converters and motor H-bridges without external diode supplementation.

FAQ

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

The maximum continuous drain current for IPP120P04P4L03AKSA1 is -114 A at T_C = 100 °C and V_GS = -10 V. This rating reflects thermal limitation of the TO-220 package, not silicon capability-bondwire limits current to -171 A at 25 °C with adequate cooling.

Does this MOSFET require a gate resistor for safe operation?

A gate resistor is recommended to dampen ringing and limit peak gate current during switching. With Q_g = 180–234 nC and typical driver rise time targets, a 3.3–10 Ω series resistor balances switching speed and EMI control without compromising gate drive strength.

Can IPP120P04P4L03AKSA1 be used in high-side configuration with 3.3 V microcontroller control?

Yes-its V_GS(th) range of -1.2 to -2.2 V ensures reliable turn-on with 3.3 V logic. However, a level-shifting gate driver is required for high-side operation to maintain sufficient V_GS across the source potential swing; direct MCU connection is only valid in low-side configurations.

Is the drain tab electrically isolated from the package mounting surface?

No-the drain (Pin 2) is directly connected to the exposed copper tab, which serves as both the primary thermal path and the main current-carrying terminal. Electrical isolation requires insulating hardware (e.g., silicone pad + shoulder washer) when mounting to a heatsink tied to system ground or another potential.
