Product details

Overview

IPP120N10S405AKSA1 from Infineon Technologies is a 100 V, 120 A N-channel enhancement-mode MOSFET in PG-TO220-3-1 package, AEC-Q101 qualified for automotive power switching, with R_DS(on) max of 5.0 mΩ at V_GS = 10 V and 100% single-pulse avalanche tested to 330 mJ at I_D = 60 A.

For engineers reviewing the IPP120N10S405AKSA1 datasheet, IPP120N10S405AKSA1 pinout, IPP120N10S405AKSA1 application, or IPP120N10S405AKSA1 equivalent, key selection criteria include junction-to-case thermal resistance (0.8 K/W), gate plateau voltage (4.9 V), reverse recovery charge (130 nC), and SOA compliance up to 100 V/120 A in continuous conduction mode.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low R_DS(on) × Q_g figure-of-merit in high-current DC-DC and motor drive stages. Its 175 °C maximum operating temperature and MSL1 rating support under-hood automotive deployment without derating.

The integrated body diode exhibits t_rr = 65 ns and Q_rr = 130 nC at V_R = 50 V, I_F = 50 A, di_F/dt = 100 A/µs, enabling hard-switched synchronous rectification with controlled commutation loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - supports 48 V and 60 V automotive battery architectures with 20 % margin
R_DS(on) max	5.0 mΩ @ V_GS = 10 V - enables ≤1.2 W conduction loss at 120 A DC
I_D continuous	120 A @ T_C = 25 °C - rated for high-current load switching with external heatsink
E_AS	330 mJ - ensures robustness against inductive turn-off transients in motor control
Q_g	91 nC max - determines gate driver current requirement (~1.8 A peak for 50 ns rise)
t_r/t_f	10 ns / 35 ns - supports >500 kHz switching in resonant topologies
R_thJC	0.8 K/W - allows direct thermal path to heatsink with minimal interface resistance

Pinout & Package

IPP120N10S405AKSA1 is housed in PG-TO220-3-1 package: insulated tab, vertical mounting, lead-free, RoHS-compliant, with drain-connected tab for thermal and electrical integration.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Low-side reference node; connects to PCB ground plane or current-sense shunt
Pin 2 (Gate)	Control input	High-impedance MOSFET gate requiring <100 nA leakage; driven via 3.5 Ω series resistor per datasheet test condition
Pin 3 (Drain)	Power output	Internally bonded to metal tab; must be electrically isolated from heatsink unless system design permits common-drain topology

Key Features

Feature	Design Value

100 % avalanche tested	Each unit verified for single-pulse ruggedness up to 330 mJ, eliminating batch-level reliability uncertainty
175 °C operation	Enables placement near heat sources (e.g., inverters, DC-DC converters) without thermal throttling
MSL1 reflow rating	Withstands peak solder temperatures up to 260 °C, compatible with standard lead-free assembly processes
Integrated body diode	Optimized for fast recovery (t_rr = 65 ns) and low Q_rr (130 nC) to reduce freewheeling losses

FAQ

What is the maximum allowable gate-source voltage for IPP120N10S405AKSA1?

The absolute maximum gate-source voltage is ±20 V. Operation beyond ±20 V risks permanent gate oxide damage. Recommended drive range is 0 V to 10 V for normal switching; gate drivers must clamp at ±20 V and limit dv/dt during turn-on to prevent unintended Miller-induced turn-on.

Does IPP120N10S405AKSA1 include an integrated body diode, and what are its key parameters?

Yes, it features a monolithic body diode with V_SD = 1.0–1.3 V at I_F = 100 A and T_j = 25 °C, t_rr = 65 ns, and Q_rr = 130 nC under specified test conditions. This diode is optimized for fast recovery and low stored charge, supporting synchronous rectification in hard-switched topologies.

How does the thermal resistance R_thJC of 0.8 K/W translate to practical heatsink design?

With R_thJC = 0.8 K/W and maximum T_j = 175 °C, a case temperature of 100 °C allows 94 W of power dissipation (ΔT = 75 K ÷ 0.8 K/W). To achieve this, the heatsink must maintain T_C ≤ 100 °C under worst-case ambient and airflow-typically requiring ≥150 cm² finned aluminum surface area in natural convection.

Is IPP120N10S405AKSA1 suitable for use in non-automotive industrial applications?

Yes-its 175 °C rating, 100 % avalanche testing, and RoHS compliance make it suitable for industrial motor drives, UPS systems, and solar inverters. However, AEC-Q101 qualification does not imply automotive qualification for end-system certification; system-level validation remains the customer's responsibility.
