Product details

Overview

IPI100N04S3-03 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TO262-3-1 package, rated for 40 V V_DS, 100 A continuous drain current at T_C = 100 °C, and ultra-low 2.5 mΩ R_DS(on) (max) at V_GS = 10 V. It delivers high-current switching in automotive powertrain control modules, battery disconnect units, and 12 V/48 V hybrid starter-generator inverters.

For engineers reviewing the IPI100N04S3-03 datasheet, IPI100N04S3-03 pinout, IPI100N04S3-03 application, or IPI100N04S3-03 equivalent, key selection criteria include its 175 °C maximum junction temperature, 100% avalanche-tested ruggedness, 0.7 K/W R_thJC, and SMD-compatible thermal performance on PCBs with 6 cm² copper area.

Technical Context

This OptiMOS®-T device uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching dynamics: typical C_iss = 8500 pF, C_oss = 2300 pF, and Crss = 385 pF at V_DS = 25 V. Its gate threshold voltage (2.1–4.0 V) ensures robust noise immunity in noisy automotive environments.

The MOSFET integrates a co-packaged body diode with 100 A continuous forward current rating, 0.85–1.3 V V_SD at 80 A, and 60 ns t_rr, enabling efficient synchronous rectification and bidirectional energy recovery in DC-DC converters and motor drives.

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
IPB100N04S3-03	PG-TO263-3-2 package; identical silicon die and electrical specs; 0.7 K/W R_thJC same	Suitable for surface-mount assembly; requires larger PCB footprint than TO262	Select when automated SMT production and board-level thermal spreading are prioritized
IPP100N04S3-03	PG-TO220-3-1 package; same die; R_thJC = 0.7 K/W but higher R_thJA due to smaller case	Better suited for prototyping and low-volume through-hole builds; limited airflow-dependent cooling	Choose for manual assembly, evaluation boards, or space-constrained non-automotive designs

Compared with IPB100N04S3-03 and IPP100N04S3-03, the IPI100N04S3-03 offers identical electrical performance in a thermally optimized through-hole package that balances manufacturability, thermal reliability, and serviceability-making it ideal for high-volume automotive power modules where mechanical robustness and field-replaceability matter.

FAQ

What is the maximum allowable gate-source voltage for IPI100N04S3-03?

The absolute maximum V_GS rating is ±20 V. Operation beyond this risks permanent gate oxide damage. For reliable long-term use, gate drive circuits should limit voltage to ≤15 V during transient conditions and maintain steady-state V_GS between 10 V (full enhancement) and 5.2 V (gate plateau), as confirmed by gate charge curves in the datasheet.

Does IPI100N04S3-03 require a gate resistor, and if so, what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. Based on measured Q_g = 110–145 nC and target t_d(on) ≈ 30 ns, a 3.3 Ω resistor is recommended when driven by a 1 A peak gate driver at 10 V, matching the test condition used in the datasheet's dynamic characterization.

Can IPI100N04S3-03 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (increasing ~0.5%/°C from 25 °C to 175 °C) enables inherent current sharing. Successful paralleling requires matched layout symmetry, identical gate drive paths, and shared source inductance minimization; application note ANPS071E provides layout guidelines for multi-device arrays.

Is the body diode in IPI100N04S3-03 suitable for continuous freewheeling in a synchronous buck converter?

Yes-the co-packaged diode supports 100 A continuous forward current at T_C = 100 °C and exhibits 0.85–1.3 V V_SD at 80 A. Its 60 ns t_rr and 95 nC Q_rr allow efficient operation up to 100 kHz, though external Schottky diodes may be preferred for >200 kHz designs to reduce recovery loss.
