Product details
Overview
IPB120N06S403ATMA2 from Infineon Technologies is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in PG-TO263-3-2 package, rated for 60 V VDS, 120 A continuous drain current at TC = 25 °C, and 2.8 mΩ max RDS(on) (SMD version). It delivers high-current switching in automotive DC-DC converters, motor control inverters, and battery disconnect circuits.
For engineers reviewing the IPB120N06S403ATMA2 datasheet, IPB120N06S403ATMA2 pinout, IPB120N06S403ATMA2 application, or IPB120N06S403ATMA2 equivalent, key selection criteria include its 0.9 K/W RthJC, 100% avalanche tested ruggedness, 175 °C operating temperature, and SMD-optimized thermal performance on 6 cm² PCB copper area.
Technical Context
This OptiMOS®-T2 power transistor uses trench-gate superjunction technology to achieve low conduction loss while maintaining fast switching with 125–160 nC total gate charge and 10120–13150 pF input capacitance. Its gate threshold voltage (2.0–4.0 V) enables robust 10 V gate drive compatibility in 12 V automotive systems.
The integrated body diode supports synchronous rectification and freewheeling with 115 ns reverse recovery time and 110 nC Qrr; its 392 mJ single-pulse avalanche energy rating ensures reliability under inductive load switching stress in motor drives and solenoid controls.

FAQ
What is the maximum allowable gate-source voltage for IPB120N06S403ATMA2?
The absolute maximum gate-source voltage is ±20 V. Operation above +15 V or below –10 V risks permanent gate oxide damage. Recommended gate drive is +10 V for full enhancement and –5 V for fast turn-off, consistent with its 2.0–4.0 V VGS(th) range and plateau voltage of 5.3 V.
Does IPB120N06S403ATMA2 include an integrated body diode, and what are its key parameters?
Yes, it features a monolithic body diode with 120 A continuous forward current rating, 115 ns reverse recovery time at 120 A and 100 A/µs di/dt, and 110 nC reverse recovery charge. These values enable efficient freewheeling in H-bridge and synchronous rectifier topologies without external diodes.
How does the PG-TO263-3-2 package affect thermal performance compared to TO-220?
The PG-TO263-3-2 package reduces junction-to-case thermal resistance to 0.9 K/W versus ~1.5 K/W for TO-220, enabling 33% higher power dissipation at equal case temperature. Its exposed drain pad must be soldered to ≥6 cm² of 70 µm copper on FR4 for specified RthJA = 40 K/W.
Is IPB120N06S403ATMA2 suitable for use in life-support equipment?
No - Infineon explicitly restricts use in life-support devices or systems unless approved in writing. This part lacks the additional process controls, documentation, and long-term reliability validation required for implantable or critical-care medical applications.
