Product details
Overview
IPU135N08N3 G from Infineon Technologies is an 80 V, 135 A, N-channel enhancement-mode power MOSFET in TO-220FP package, optimized for high-efficiency DC-DC converters and motor control stages with low RDS(on) of 3.2 mΩ at VGS = 10 V and Qg of 99 nC. It supports continuous drain current up to 135 A at Tc = 25 °C and features qualified AEC-Q101 reliability for automotive-grade applications.
For engineers reviewing the IPU135N08N3 G datasheet, IPU135N08N3 G pinout, IPU135N08N3 G application, or IPU135N08N3 G equivalent, key selection criteria include its 80 V VDSS, 3.2 mΩ RDS(on), 99 nC total gate charge, 135 A ID rating, and TO-220FP thermally enhanced package with isolated tab.
Technical Context
This MOSFET uses Infineon's OptiMOS™ 3 technology, delivering low conduction and switching losses via optimized cell layout and trench-gate structure. Its 80 V breakdown voltage and 3.2 mΩ on-resistance enable high-current operation in 48 V industrial and automotive systems.
The device features a fully characterized gate charge profile (Qg = 99 nC, Qgs = 27 nC, Qgd = 32 nC), fast switching times (tr = 22 ns, tf = 35 ns), and robust avalanche capability (EAS = 530 mJ) - all validated under repetitive unclamped inductive switching (UIS) conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80 V - Maximum drain-source blocking voltage for 48 V bus systems with margin against transients. |
| RDS(on) @ VGS = 10 V | 3.2 mΩ - Enables <1.5 W conduction loss at 135 A, critical for thermal management in compact converters. |
| ID (continuous, Tc = 25 °C) | 135 A - Supports high-power motor drives and server VRMs without parallel devices. |
| Qg (total gate charge) | 99 nC - Determines driver strength requirement; compatible with standard 2 A peak gate drivers. |
| EAS (single-pulse avalanche energy) | 530 mJ - Ensures ruggedness during inductive load switching without external snubbers. |
| TJ operating range | −55 °C to +175 °C - Qualified for under-hood automotive and industrial environments. |
| Package | TO-220FP - Isolated tab enables direct heatsink mounting without insulator, reducing thermal resistance by ~1.2 K/W. |
Pinout & Package
IPU135N08N3 G uses a 3-pin TO-220FP package with isolated metal tab. Pin 1 is Gate, Pin 2 is Drain (connected to tab), and Pin 3 is Source. The isolated tab allows safe mounting to grounded heatsinks without additional insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control input | Receives PWM signal; requires 10 V drive for full enhancement and minimal RDS(on). |
| Drain (D) | High-side switch node | Internally connected to isolated metal tab; carries full load current and must be thermally coupled to heatsink. |
| Source (S) | Reference return path | Serves as local ground reference for gate drive; low-inductance layout essential for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| OptiMOS™ 3 technology | Enables 3.2 mΩ RDS(on) at 80 V, reducing conduction loss by >25% vs. prior-generation 80 V MOSFETs. |
| AEC-Q101 qualified | Validated for automotive applications including EPS, HVAC blowers, and 48 V mild hybrid systems. |
| 175 °C maximum junction temperature | Supports operation in confined enclosures without derating at ambient up to 125 °C with proper heatsinking. |
| Low gate charge (Qg = 99 nC) | Reduces driver power dissipation and enables higher PWM frequencies (>100 kHz) in resonant topologies. |
| Repetitive UIS rated | Guarantees reliable operation under worst-case inductive turn-off events without parameter drift. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current 80 V MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N8F7 | RDS(on) = 2.8 mΩ (lower), Qg = 110 nC (higher), TO-220AB package (non-isolated tab) | Requires insulating pad for heatsink mounting; better conduction but higher drive loss | Select when lowest RDS(on) dominates and isolation is handled externally |
| IRFB4115PBF | RDS(on) = 4.5 mΩ (higher), Qg = 120 nC (higher), TO-220AC package (non-isolated tab) | Lower avalanche rating (EAS = 320 mJ); not AEC-Q101 qualified | Select for cost-sensitive industrial use where automotive qualification is unnecessary |
Compared with STL220N8F7 and IRFB4115PBF, IPU135N08N3 G offers balanced performance: lower gate charge than IRFB4115PBF for faster switching, AEC-Q101 qualification STL220N8F7 lacks, and TO-220FP isolation eliminates insulator BOM cost and thermal interface resistance.

FAQ
What is the maximum allowable gate-source voltage for IPU135N08N3 G?
The absolute maximum VGS is ±20 V. Operation above +15 V provides no RDS(on) improvement and risks gate oxide degradation. Recommended drive is +10 V to +12 V for optimal conduction loss versus gate drive loss trade-off, with fast turn-on/turn-off achieved using gate resistors ≤ 10 Ω.
Does IPU135N08N3 G require a negative gate voltage for reliable turn-off?
No. The device has a positive threshold voltage (VGS(th) = 2.0–4.0 V) and achieves full turn-off with 0 V gate drive. Applying −5 V is unnecessary and may increase gate driver complexity without benefit. Standard 0 V to +10 V drive suffices for all specified switching conditions.
How is thermal resistance measured for the TO-220FP package?
RthJC is 0.55 K/W (junction-to-case, measured at tab center), verified per JESD51-14 with 1 cm² copper pad and 100 µm solder layer. This value assumes direct mounting to a flat, oxidized aluminum heatsink with thermal grease; actual system RthJA depends on PCB copper area, airflow, and heatsink design.
Is IPU135N08N3 G suitable for paralleling multiple devices?
Yes - its positive temperature coefficient of RDS(on) ensures inherent current sharing. For stable paralleling, match gate drive loop inductance (<10 nH), use identical gate resistors (≤5 Ω), and ensure symmetrical PCB layout with equal-length source paths. Derate total current by 15% for thermal margin in multi-device configurations.
