Product details

Overview

IPB120N06S403ATMA1 from Infineon Technologies is a 60 V, 120 A N-channel enhancement-mode power MOSFET in PG-TO263-3-2 package, AEC-Q101 qualified for automotive applications, with R_DS(on) max of 2.8 mΩ at V_GS = 10 V and 100% single-pulse avalanche tested to 392 mJ. It serves as a high-current main switch in 12 V/24 V DC-DC converters and motor control inverters.

For engineers reviewing the IPB120N06S403ATMA1 datasheet, IPB120N06S403ATMA1 pinout, IPB120N06S403ATMA1 application, or IPB120N06S403ATMA1 equivalent, key selection criteria include its 0.9 K/W junction-to-case thermal resistance, 175 °C maximum operating temperature, SMD-compatible TO263 footprint, and integrated body diode with 115 ns reverse recovery time.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in high-frequency hard-switched topologies. Its gate threshold voltage (2.0–4.0 V) enables robust TTL/CMOS-level drive compatibility while maintaining noise immunity.

The MOSFET features a fully characterized dynamic capacitance profile (C_iss = 10.1–13.2 nF, C_oss = 2.48–3.22 nF), defined gate charge (Q_g = 125–160 nC), and controlled turn-on/turn-off timing (t_d(on) = 40 ns, t_d(off) = 80 ns) - enabling precise dead-time management in half-bridge configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 12 V/24 V automotive battery rails with 2× safety margin against transients
R_DS(on) max	2.8 mΩ at V_GS = 10 V - enables ≤1.7 W conduction loss at 120 A continuous drain current
I_D continuous	120 A at T_C = 25 °C - rated for high-power motor phase switches and DC-DC primary-side switches
E_AS	392 mJ - withstands single-pulse inductive energy without failure in unclamped inductive switching
R_thJC	0.9 K/W - allows direct heatsink mounting for efficient thermal path from die to case
Q_g	125–160 nC - determines gate driver current requirement (~1.6 A peak for 100 ns rise time)
t_r/t_f	10 ns / 15 ns - supports >500 kHz switching in resonant and synchronous rectifier designs

Pinout & Package

IPB120N06S403ATMA1 uses the PG-TO263-3-2 surface-mount package (D²PAK), with drain-connected tab for thermal and electrical connection to PCB copper area. The three terminals are arranged in standard D²PAK layout: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Receives 0–10 V logic-level signal; requires <160 nC charge for full enhancement
Pin 2 (Drain)	High-side power node	Internally connected to exposed copper tab; must be soldered to ≥6 cm² PCB copper for R_thJA = 40 K/W
Pin 3 (Source)	Reference return path	Serves as local ground reference for gate drive; carries full load current back to source rail

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive under-hood use up to 175 °C junction temperature
100% avalanche tested	Guarantees robustness in unclamped inductive switching events common in motor drives
Green Product (RoHS)	Lead-free and halogen-free construction compliant with EU Directive 2011/65/EU
Optimized body diode	Q_rr = 110 nC and t_rr = 115 ns enable efficient synchronous rectification without external Schottky
MSL1 reflow rating	Withstands peak reflow temperatures up to 260 °C - compatible with standard lead-free assembly processes

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
IPP120N06S4-03	Same die, TO-220-3-1 through-hole package; R_thJC = 0.9 K/W but higher R_thJA (62 K/W)	Preferred for prototyping, low-volume industrial controls where manual assembly is used	Select when board space allows larger footprint and thermal management relies on clip-on heatsinks
IPI120N06S4-03	Same die, TO-262-3-1 package; identical R_thJC, slightly lower R_thJA than TO-220 but no exposed drain tab	Suitable for cost-sensitive automotive modules where wave-soldering is required	Choose when automated through-hole assembly is mandated and PCB copper area is limited

Compared with IPP120N06S4-03 and IPI120N06S4-03, IPB120N06S403ATMA1 delivers superior thermal performance in SMD layouts due to its exposed drain tab and optimized PCB copper coupling, making it the preferred choice for high-power density automotive and server applications where airflow and board real estate are constrained.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The IPB120N06S403ATMA1 is rated for continuous operation up to 175 °C junction temperature, validated per AEC-Q101 stress testing. Derating curves show 120 A current capability at T_C = 25 °C, decreasing linearly to ~75 A at T_C = 100 °C, assuming R_thJC = 0.9 K/W and proper heatsinking.

Does this MOSFET require a negative gate voltage for reliable turn-off in high-noise environments?

No - the device has a gate threshold voltage range of 2.0–4.0 V and exhibits stable turn-off behavior with 0 V gate drive. However, applying –5 V enhances noise immunity in high-dV/dt motor drive applications; the absolute maximum V_GS is ±20 V, so –5 V is within safe limits and improves Miller immunity.

Can the integrated body diode replace an external Schottky in synchronous rectification?

Yes - the body diode is fully characterized with t_rr = 115 ns and Q_rr = 110 nC at T_j = 25 °C, enabling use in synchronous buck topologies up to 300 kHz. At elevated temperatures, Q_rr increases to ~180 nC at 175 °C, so layout optimization and gate drive tuning are recommended for >200 kHz operation.

Is the PG-TO263-3-2 package compatible with standard reflow profiles for lead-free assembly?

Yes - the device is MSL1 rated and qualified for peak reflow temperatures up to 260 °C per J-STD-020. Its copper leadframe and matte tin plating ensure reliable wetting and void-free solder joints under standard IPC-A-610 Class 2/3 profiles, including ramp rates up to 3 °C/s and soak times of 60–120 s at 150–200 °C.
