Product details
Overview
IPP039N04LGHKSA1 from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TO220-3 package, rated for 40 V VDS, 3.9 mΩ RDS(on) at VGS = 10 V, and 80 A continuous drain current at TC = 25 °C. It features 100% avalanche testing, optimized gate charge × RDS(on) figure-of-merit (FOM), and is qualified per JEDEC standards for DC/DC converters and SMPS applications.
For engineers reviewing the IPP039N04LGHKSA1 datasheet, IPP039N04LGHKSA1 pinout, IPP039N04LGHKSA1 application, or IPP039N04LGHKSA1 equivalent, key selection criteria include its 4.5 V logic-level gate drive compatibility, low 3.9 mΩ on-resistance at 10 V, 59–78 nC total gate charge, 1.2–2.0 V gate threshold voltage, and thermal resistance of 1.6 K/W junction-to-case.
Technical Context
This MOSFET employs Infineon's OptiMOS™3 silicon technology, delivering enhanced switching speed and conduction efficiency for synchronous rectification and high-frequency DC/DC topologies. Its low RDS(on) and optimized Ciss/Coss ratio (typ. 4600 pF / 820 pF) support reduced switching losses in buck, boost, and LLC converters operating up to 1 MHz.
The device integrates a robust body diode with 50 nC reverse recovery charge (Qrr) and 0.92–1.2 V forward voltage (VSD) at 80 A, enabling reliable operation in hard-switched and synchronous FET configurations without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage compatible with 36 V nominal input rails and 12/24 V automotive or industrial bus systems. |
| RDS(on) max | 3.9 mΩ @ VGS = 10 V - Enables <1.5 W conduction loss at 80 A, critical for high-current point-of-load regulators. |
| ID cont. | 80 A @ TC = 25 °C - Supports high-power density designs with minimal parallel devices in server VRMs or telecom PSUs. |
| Qg total | 59–78 nC - Determines gate driver strength requirement; enables efficient 500 kHz–1 MHz switching with standard 2 A peak drivers. |
| VGS(th) | 1.2–2.0 V - Ensures full enhancement with 3.3 V or 5 V logic-level controllers, eliminating need for level shifters. |
| EAS | 60 mJ - Confirmed single-pulse avalanche energy supports robustness against inductive load transients and layout parasitics. |
| RthJC | 1.6 K/W - Allows direct thermal coupling to heatsink; enables >70 W dissipation with modest heatsinking in TO-220 footprint. |
Pinout & Package
IPP039N04LGHKSA1 uses the PG-TO220-3-1 package: insulated tab, vertical mounting, through-hole leaded configuration with drain connected to the metal tab. Thermal path is optimized via direct tab-to-heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side reference node; connects to ground or return path in buck/synchronous rectifier topologies. |
| Pin 2 (Gate) | Control input | High-impedance MOS gate requiring <100 nC drive; sensitive to ESD and ringing-requires local RC snubber or gate resistor. |
| Pin 3 (Drain) | Power output / high-side switch node | Internally bonded to metal tab; must be electrically isolated from heatsink unless using insulating pad or clip-mount solution. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS ≥ 4.5 V, enabling direct interfacing with microcontrollers and PWM ICs without gate drivers. |
| Optimized FOM (Qg × RDS(on)) | ~230 nC·mΩ - Balances switching and conduction losses for highest efficiency in 300 kHz–1 MHz DC/DC stages. |
| 100% avalanche tested | Guarantees ruggedness under unclamped inductive switching events common in motor drives and relay control circuits. |
| Pb-free & halogen-free | Complies with RoHS Directive 2011/65/EU and IEC 61249-2-21, supporting green manufacturing and end-of-life compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPB039N04LG | Same die, PG-TO263-3 package; RthJC = 1.3 K/W; slightly lower Coss (750 pF typ.) | Better thermal performance in surface-mount PCB layouts with large copper pour; less suitable for through-hole assembly | Select for space-constrained SMT designs where board-level thermal management dominates over mechanical mounting flexibility. |
| IRL1404ZPBF | 40 V, 4.0 mΩ, 160 A (TC=25°C), higher Qg (110 nC), TO-220AB package, no avalanche rating | Lacks JEDEC qualification and 100% avalanche test; higher gate drive demand limits high-frequency use | Acceptable for cost-sensitive, non-critical 100 kHz applications where transient robustness is not required. |
Compared with IPB039N04LG, IPP039N04LGHKSA1 trades 0.3 K/W higher junction-to-case thermal resistance for through-hole reliability and simplified heatsink mounting; versus IRL1404ZPBF, it delivers verified avalanche ruggedness and 25% lower gate charge-critical for high-efficiency, high-reliability SMPS.

FAQ
What is the maximum safe operating temperature for IPP039N04LGHKSA1?
The junction temperature must not exceed 175 °C under any operating condition. At TC = 100 °C, the device supports 73 A continuous drain current with VGS = 4.5 V. Derating curves in the datasheet show linear reduction from 80 A at 25 °C to zero at 175 °C junction temperature, assuming proper heatsinking and RthJC = 1.6 K/W.
Can IPP039N04LGHKSA1 be used in synchronous rectification mode?
Yes-it is explicitly characterized for synchronous rectifier use, with diode forward voltage VSD = 0.92–1.2 V at 80 A and reverse recovery charge Qrr = 50 nC. Its low RDS(on) and fast body diode enable >3% efficiency gain over Schottky solutions in 12 V–48 V output buck converters operating above 200 kHz.
Is the drain tab electrically isolated in the PG-TO220-3 package?
No-the drain is internally connected to the metal tab. Electrical isolation from the heatsink requires a thermally conductive but electrically insulating pad (e.g., mica or ceramic) or insulating clip mount. Failure to isolate will short the drain to chassis ground if the heatsink is grounded.
Does IPP039N04LGHKSA1 require a gate resistor for stability?
Yes-a series gate resistor (typically 5–22 Ω) is recommended to dampen gate-source ringing caused by PCB trace inductance and driver output impedance. Without it, oscillation near 100–200 MHz can cause false turn-on, increased switching loss, and potential gate oxide stress, especially when driven by fast logic-level controllers.
