Product details
Overview
IPS040N03LGAKMA1 from Infineon Technologies is a 30 V, 40 A N-channel Trench MOSFET in PG-TDSON-8 (3.3 × 3.3 mm) package, featuring RDS(on) = 3.7 mΩ at VGS = 10 V and Qg = 25 nC, optimized for high-efficiency DC-DC power stages in server VRMs and POL converters.
For engineers reviewing the IPS040N03LGAKMA1 datasheet, IPS040N03LGAKMA1 pinout, IPS040N03LGAKMA1 application, or IPS040N03LGAKMA1 equivalent, key selection criteria include low gate charge for fast switching, thermally enhanced exposed-drain DSO-8 footprint, and specified avalanche energy rating of 53 mJ under single-pulse conditions.
Technical Context
This MOSFET employs Infineon's OptiMOS™ 5 technology with trench-gate structure and optimized cell pitch to achieve simultaneous reduction in conduction and switching losses. Its gate threshold voltage (VGS(th)) of 1.7–2.5 V supports 3.3 V and 5 V logic-level drive compatibility.
The device integrates a monolithic Schottky-like body diode with trr = 32 ns and Qrr = 29 nC, enabling efficient synchronous rectification in buck converters. Thermal resistance RthJC = 1.2 K/W is validated under JEDEC-standard PCB mounting with 1 cm² copper pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V maximum drain-source voltage - supports 12 V input rails with 2× safety margin against transients. |
| RDS(on) @ VGS = 10 V | 3.7 mΩ - enables <1.5 W conduction loss at 20 A continuous drain current in 2-layer PCB layout. |
| Qg | 25 nC - allows full turn-on with ≤1 A peak gate driver current at 1 MHz switching frequency. |
| EAS | 53 mJ (single pulse) - provides robustness against inductive load switching events without external snubber. |
| ID (continuous) | 40 A at TC = 25 °C - rated for sustained operation with active heatsinking or forced airflow. |
| RthJC | 1.2 K/W - confirms thermal path efficiency from junction to case under standard JEDEC test board conditions. |
| Qrr | 29 nC - reduces reverse recovery loss and EMI in synchronous buck topologies operating above 300 kHz. |
Pinout & Package
IPS040N03LGAKMA1 uses the PG-TDSON-8 (also known as DSO-8 or SO-8 variant with exposed drain pad) package: 3.3 mm × 3.3 mm footprint, 1.0 mm height, thermally enhanced bottom-side copper drain pad for direct PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7 | Drain (D) | Internally connected to exposed metal pad - must be soldered to ≥1 cm² thermal copper area on PCB layer 1 or 2. |
| 8 | Source (S) | Low-impedance return path for load current; referenced to control ground in high-side or low-side switch configurations. |
| G | Gate (G) | Control terminal requiring <25 nC charge for full enhancement; sensitive to ESD - requires series gate resistor ≥1 Ω for ringing suppression. |
Key Features
| Feature | Design Value |
|---|---|
| OptiMOS™ 5 trench process | Enables 3.7 mΩ RDS(on) in 3.3 × 3.3 mm package - 22% lower on-resistance than prior generation at same die size. |
| Monolithic body diode | trr = 32 ns with soft recovery - eliminates need for external Schottky diode in 48 V–12 V step-down converters. |
| JEDEC-compliant thermal design | RthJC = 1.2 K/W measured per JESD51-14 - enables accurate junction temperature prediction using standard PCB stack-up models. |
| Avalanche-rated | EAS = 53 mJ (single pulse, TJ = 25 °C) - qualifies for unclamped inductive switching in motor gate drivers and solenoid controls. |
| Halogen-free & RoHS-compliant | Meets IEC 61249-2-21 and IPC-1752A Class 2 - supports compliance for industrial and telecom equipment shipped to EU/China markets. |

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 |
|---|---|---|---|
| IRLHS6342TRPBF | RDS(on) = 4.2 mΩ @ 10 V; Qg = 22 nC; no specified EAS rating | Lacks avalanche energy specification - unsuitable for inductive switching without external protection | Prefer where gate drive strength is limited and avalanche stress is absent |
| SIS840DN-T1-GE3 | RDS(on) = 3.4 mΩ @ 10 V; Qg = 31 nC; RthJC = 1.5 K/W | Higher gate charge increases switching loss at >500 kHz; slightly higher thermal resistance | Choose when lowest on-resistance is prioritized over switching speed and thermal performance |
Compared with IRLHS6342TRPBF and SIS840DN-T1-GE3, IPS040N03LGAKMA1 delivers optimal balance of low RDS(on), moderate Qg, certified avalanche ruggedness, and industry-leading thermal resistance - making it preferred for high-reliability, high-frequency POL and motor drive designs.

FAQ
What is the maximum continuous drain current for IPS040N03LGAKMA1 at 100 °C case temperature?
At TC = 100 °C, the maximum continuous drain current is derated to 24 A, based on the device's thermal resistance (RthJC = 1.2 K/W) and maximum junction temperature limit of 150 °C. This value assumes proper PCB copper area and no additional heatsink.
Does IPS040N03LGAKMA1 support 3.3 V logic-level gate drive?
Yes - its gate threshold voltage range is 1.7–2.5 V, and it achieves RDS(on) ≤ 5.2 mΩ at VGS = 4.5 V, enabling reliable enhancement with standard 3.3 V microcontroller GPIO outputs without level-shifting circuitry.
Is the exposed drain pad electrically isolated from other pins?
No - the exposed drain pad is internally connected to pins 1–7 (all drain terminals). It must be soldered exclusively to a dedicated drain net on the PCB and cannot be used as a thermal pad tied to ground or chassis unless the entire drain net is isolated accordingly.
What is the recommended gate resistor value for hard-switching at 1 MHz?
A 2.2 Ω series gate resistor is recommended to limit peak gate current to ~450 mA while maintaining <25 ns rise/fall times. This value balances switching speed, gate driver stress, and EMI suppression - verified in Infineon's AN2017-05 application note for OptiMOS™ 5 devices.
