Product details

Overview

IPI120N08S404AKSA1 from Infineon Technologies is an AEC-Q101-qualified N-channel enhancement-mode OptiMOS™-T2 power MOSFET in PG-TO262-3-1 package, rated for 80 V V_DS, 4.1 mΩ max R_DS(on) at 10 V V_GS, 120 A continuous drain current at T_C = 25°C, and 175°C maximum junction temperature. It integrates a robust body diode and is 100% avalanche tested for automotive and industrial switching applications.

For engineers reviewing the IPI120N08S404AKSA1 datasheet, IPI120N08S404AKSA1 pinout, IPI120N08S404AKSA1 application, or IPI120N08S404AKSA1 equivalent, key selection criteria include R_DS(on) stability over temperature, single-pulse avalanche energy (310 mJ), gate charge profile (Q_g = 70–95 nC), thermal resistance (R_thJC = 0.84 K/W), and AEC-Q101 qualification status.

Technical Context

This MOSFET employs trench-based silicon technology optimized for low conduction and switching losses in high-current DC-DC converters and motor control stages. Its gate threshold voltage (2.0–4.0 V) enables reliable turn-on with standard 5 V or 10 V logic-level drivers, while its 100% avalanche-tested design ensures ruggedness under inductive load switching.

The device features a low reverse transfer capacitance (C_rss = 100–200 pF) and fast switching times (t_d(on) = 20 ns, t_f = 35 ns), supporting high-frequency operation up to 200 kHz in synchronous rectification and H-bridge configurations. Its integrated body diode exhibits V_SD = 0.9–1.3 V at 100 A and t_rr = 70 ns, enabling efficient freewheeling without external Schottky supplementation.

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
IPP120N08S4-04	Same die, PG-TO220-3-1 package; higher R_thJA (62 K/W vs. 40 K/W on PCB)	Limited to lower-power applications (<80 A continuous) due to reduced thermal performance	Select when cost-sensitive TO-220 footprint is required and heatsinking is less constrained.
IPB120N08S4-04	Same die, PG-TO263-3-2 SMD package; identical R_DS(on) and SOA, but requires reflow-compatible layout	Suitable for automated SMT assembly in compact EVSE and ADAS modules	Select for board space optimization and volume production where thermal pad soldering is feasible.

Compared with IPP120N08S4-04 and IPB120N08S4-04, IPI120N08S404AKSA1 offers superior thermal interface via TO-262's isolated tab and mechanical robustness for under-hood vibration, making it optimal for high-reliability engine bay switching where manual heatsink mounting is preferred over SMT or TO-220 constraints.

FAQ

Is IPI120N08S404AKSA1 pin-compatible with IPP120N08S4-04?

Yes - both use three-pin through-hole packages with identical pinout (Drain–Source–Gate) and mechanical footprint. However, IPI120N08S404AKSA1 uses PG-TO262-3-1 with an isolated metal tab, while IPP120N08S4-04 uses PG-TO220-3-1 with non-isolated tab; electrical isolation requirements must be verified per board layout.

What is the maximum recommended gate resistor value for driving IPI120N08S404AKSA1 at 100 kHz?

For 100 kHz PWM with Q_g = 95 nC and typical gate driver output impedance <2 Ω, a series gate resistor of 5–10 Ω balances switching speed (t_f ≈ 35 ns) and ringing suppression. Values >15 Ω increase switching loss significantly without improving EMI in most automotive layouts.

Does this MOSFET require a negative gate voltage for safe turn-off in high-dv/dt environments?

No - the device has a gate threshold voltage of 2.0–4.0 V and is fully enhanced at V_GS = 10 V. A gate drive of 0 V is sufficient for turn-off; applying –5 V is unnecessary and not specified in the datasheet. Stable 0 V return path and low-inductance source routing are more critical than negative bias.

Can IPI120N08S404AKSA1 replace older OptiMOS™-T1 devices like IPP100N08S2L-04 in existing designs?

Yes - it offers lower R_DS(on) (4.1 mΩ vs. 5.2 mΩ), improved avalanche ruggedness (310 mJ vs. 240 mJ), and AEC-Q101 qualification. Layout compatibility is confirmed by identical TO-262-3-1 footprint and pinout; thermal design should be re-verified due to higher current capability and slightly different R_thJC.
