Product details
Overview
IPU050N03L G from Infineon Technologies is a 30 V, 50 A, logic-level N-channel Trench MOSFET in PG-TO252-3 (DPAK) package, featuring RDS(on) = 4.8 mΩ @ VGS = 10 V and Qg = 37 nC, optimized for high-efficiency DC-DC converters and motor control in automotive body electronics.
For engineers reviewing the IPU050N03L G datasheet, IPU050N03L G pinout, IPU050N03L G application, or IPU050N03L G equivalent, key selection criteria include its low gate threshold (VGS(th) = 1.7 V), fast switching (ton = 19 ns, toff = 32 ns), and robust avalanche rating (EAS = 135 mJ), critical for 12 V automotive load switching and synchronous rectification.
Technical Context
This MOSFET uses Infineon's OptiMOS™ 5 technology with trench-gate structure and optimized charge balance, enabling low conduction loss while maintaining fast turn-on/turn-off transitions. Its logic-level gate drive supports direct interface with 3.3 V and 5 V microcontrollers without level-shifting.
The device features integrated ESD protection (HBM Class 2), specified for continuous drain current up to 50 A at TC = 25 °C, and operates across –55 °C to +175 °C junction temperature range - validated per AEC-Q101 for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum drain-source blocking voltage compatible with 12 V automotive systems and 24 V industrial rails. |
| RDS(on) max | 4.8 mΩ @ VGS = 10 V - Enables <1.2 W conduction loss at 50 A, reducing heatsink requirements in high-current switches. |
| Qg | 37 nC - Low total gate charge minimizes driver power and enables efficient operation at >200 kHz PWM frequencies. |
| VGS(th) | 1.7 V (min), 2.5 V (typ) - Ensures full enhancement with standard logic-level MCU outputs, eliminating external gate drivers. |
| ID cont | 50 A @ TC = 25 °C - Supports high-current loads such as HVAC actuators, seat motors, and LED headlamp drivers. |
| EAS | 135 mJ - Rated single-pulse avalanche energy allows safe operation under inductive switching stress without snubbers. |
| ton/toff | 19 ns / 32 ns - Fast switching reduces transition losses and EMI generation in high-frequency DC-DC stages. |
Pinout & Package
Package: PG-TO252-3 (DPAK), surface-mount, thermally enhanced with exposed drain pad for PCB copper thermal spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power return path for load current | Connected to ground or low-side reference; ties directly to PCB ground plane for minimal loop inductance. |
| Pin 2 (Gate) | Control input for channel conduction | Logic-level compatible; requires <2.5 V to turn on fully; sensitive to ESD - needs series resistor and local decoupling. |
| Pin 3 (Drain) | High-side power input terminal | Internally connected to exposed metal pad; must be soldered to large copper area for thermal management and current handling. |
Key Features
| Feature | Design Value |
|---|---|
| OptiMOS™ 5 trench technology | Delivers 20% lower RDS(on) × Qg figure-of-merit vs. prior generation, improving efficiency in 100–500 kHz SMPS. |
| AEC-Q101 qualified | Validated for automotive applications including engine bay and cabin modules - supports 15-year lifetime under thermal cycling. |
| Enhanced avalanche ruggedness | Guaranteed 135 mJ single-pulse EAS enables reliable inductive load switching without external clamping diodes. |
| Low gate threshold dispersion | VGS(th) range of 1.7–2.5 V ensures consistent turn-on behavior across temperature and production lots. |
| Thermally optimized DPAK | Exposed drain pad with 1.5 cm² recommended copper area achieves RthJC = 1.5 K/W, enabling 50 A operation at TC ≤ 85 °C. |

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 |
|---|---|---|---|
| STL220N3LLH6 | RDS(on) = 3.8 mΩ @ 10 V, but higher Qg = 52 nC and no AEC-Q101 qualification. | Better conduction loss, but slower switching and unqualified for automotive - suited for industrial SMPS only. | Select when lowest RDS(on) dominates and automotive qualification is unnecessary. |
| IRL3803PBF | Legacy logic-level MOSFET with RDS(on) = 6.0 mΩ @ 10 V and Qg = 42 nC; not AEC-Q101 qualified. | Higher conduction loss and older process - acceptable for cost-sensitive non-automotive loads below 30 A. | Choose only for legacy design refresh where footprint compatibility is mandatory and performance margin exists. |
Compared with STL220N3LLH6 and IRL3803PBF, IPU050N03L G delivers superior switching efficiency (lower Qg × RDS(on)), guaranteed automotive reliability, and tighter VGS(th) tolerance - making it optimal for new designs targeting 12 V/24 V high-current switching in harsh environments.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The IPU050N03L G has a rated maximum junction temperature of +175 °C. Continuous operation at this limit requires strict thermal design: minimum 1.5 cm² copper pour under the exposed drain pad, 2 oz copper, and forced airflow or heatsinking. Derating to 150 °C is recommended for automotive applications to ensure 15-year reliability under thermal cycling.
Does this MOSFET require a gate resistor, and what value is recommended?
Yes - a gate resistor is required to dampen ringing and control dV/dt. For typical 12 V automotive switching at 200 kHz, a 4.7 Ω to 10 Ω series resistor between driver and gate is recommended. Lower values (≤4.7 Ω) may be used with robust gate drivers to minimize ton; higher values (>15 Ω) suppress EMI but increase switching losses.
Is the IPU050N03L G suitable for reverse polarity protection?
No - as an N-channel MOSFET in DPAK, it lacks internal body diode orientation for reverse polarity protection. When used in high-side configuration, the body diode conducts during reverse connection, causing failure. For reverse polarity protection, a P-channel MOSFET (e.g., IPB180P04P4) or dedicated protection IC is required.
Can this part replace the older IPU050N03L in existing designs?
Yes - IPU050N03L G is a qualified green (halogen-free, RoHS-compliant) successor to IPU050N03L, with identical pinout, electrical specs, and thermal performance. The "G" suffix denotes updated material content and packaging; no layout or firmware changes are needed for drop-in replacement in qualified designs.
