Product details
Overview
IPI147N12N3GAKSA1 from Infineon Technologies is a 120 V, 147 A, 3.8 mΩ N-channel enhancement-mode power MOSFET in PG-TO220-3 package, optimized for high-frequency synchronous rectification and DC-DC conversion in server VRMs and telecom power supplies.
For engineers reviewing the IPI147N12N3GAKSA1 datasheet, IPI147N12N3GAKSA1 pinout, IPI147N12N3GAKSA1 application, or IPI147N12N3GAKSA1 equivalent, key selection criteria include RDS(on) at 10 V gate drive, avalanche energy rating, gate charge profile, and thermal resistance under PCB-mounted conditions.
Technical Context
This device employs Infineon's OptiMOS™ 3 technology with trench-gate structure to achieve low conduction loss and fast switching performance. It supports continuous drain current up to 147 A at TC = 25 °C and withstands 120 V VDS with guaranteed avalanche capability per single-pulse test.
Its gate threshold voltage (2.0–4.0 V typ.) enables robust TTL/CMOS-level drive compatibility, while the low Qg (79 nC) and Qgd (27 nC) minimize switching losses in hard-switched topologies operating above 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 120 V - Maximum drain-source blocking voltage; suitable for 48 V input bus systems with 2× safety margin. |
| RDS(on) @ VGS = 10 V | 3.8 mΩ max - Enables <1.2 W conduction loss at 147 A, critical for high-efficiency VRM designs. |
| ID (cont.) @ TC = 25 °C | 147 A - Continuous current rating defined at case temperature; requires ≥10 cm² copper area for thermal management. |
| Qg (total gate charge) | 79 nC - Low drive power requirement; reduces gate driver stress in high-frequency synchronous buck converters. |
| ZthJC (max) | 0.35 K/W - Junction-to-case thermal resistance; enables 100 W dissipation with 35 K ΔT between junction and heatsink. |
| EAS (single pulse) | 520 mJ - Avalanche energy rating ensures robustness against inductive switching transients without external snubbers. |
Pinout & Package
PG-TO220-3 package with isolated tab (drain-connected), standard through-hole mounting, and vertical lead frame for enhanced thermal transfer to heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power return path for load current | Low-inductance source connection; ties directly to PCB ground plane for EMI control. |
| Pin 2 (Gate) | Control terminal for channel conduction | High-impedance input requiring <100 Ω series gate resistor to damp ringing during fast switching. |
| Pin 3 (Drain) | Main current-carrying terminal (tab-connected) | Internally bonded to metal tab; must be electrically isolated from heatsink unless system design permits common-drain configuration. |
Key Features
| Feature | Design Value |
|---|---|
| OptiMOS™ 3 trench technology | Enables 3.8 mΩ RDS(on) at 120 V rating-25% lower on-resistance than prior-generation 120 V MOSFETs. |
| 100% avalanche tested | Guarantees single-pulse EAS ≥ 520 mJ, eliminating need for external clamping in flyback or LLC resonant circuits. |
| Lead-free and RoHS-compliant | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL1); no pre-bake required before reflow soldering. |
| Enhanced dv/dt ruggedness | Rated for 4.5 V/ns transient immunity-prevents false turn-on in high-noise motor drive or industrial SMPS environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current 120 V MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPP147N12N3GXKSA1 | Same die, PG-TO263-3 package; 0.45 K/W ZthJC; 10% higher RDS(on) due to different bond wire layout. | Better suited for surface-mount automated assembly; requires larger PCB copper area for equivalent thermal performance. | Select when board space constraints favor SMD over through-hole, and thermal budget allows +0.4 mΩ RDS(on). |
| IPB144N12N3GAKSA1 | 120 V, 144 A, 4.2 mΩ RDS(on); identical gate charge and avalanche rating; same PG-TO220-3 footprint. | Drop-in replacement with 3 A lower current rating; validated for identical VRM and telecom use cases. | Choose when inventory availability favors IPB144N12N3G and 144 A rating meets system peak current requirements. |
Compared with IPP147N12N3GXKSA1, IPI147N12N3GAKSA1 offers lower thermal resistance and tighter RDS(on) tolerance in through-hole form; versus IPB144N12N3GAKSA1, it delivers +3 A current headroom and -0.4 mΩ on-resistance for margin-critical high-power designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C. For reliable long-term operation, Infineon recommends limiting Tj to ≤150 °C under worst-case ambient and power dissipation conditions. Derating curves in the datasheet define safe operating area boundaries based on pulse width and duty cycle.
Is the drain tab electrically isolated from the package leads?
No-the metal tab is internally connected to the drain terminal (Pin 3). Electrical isolation from the heatsink must be implemented using insulating thermal pads or mica washers rated for ≥120 V working voltage and thermal conductivity ≥1.5 W/m·K.
Does this MOSFET require negative gate voltage for reliable turn-off?
No-turn-off is fully achieved with 0 V gate drive. However, applying –5 V enhances noise immunity in high-dv/dt environments. The gate threshold voltage range (2.0–4.0 V) ensures clean turn-on with standard 5 V or 10 V logic-level drivers without risk of partial enhancement.
Can IPI147N12N3GAKSA1 replace older OptiMOS™ 2 devices in existing designs?
Yes-pin-compatible with OptiMOS™ 2 120 V parts (e.g., IPP116N12N3G), offering lower RDS(on), reduced gate charge, and improved thermal performance. Layout changes are not required, but gate drive strength should be verified to handle the faster switching edges.
