Product details
Overview
IPP50CN10NGXKSA1 from Infineon Technologies is a 100 V, 50 A N-channel enhancement-mode power MOSFET in TO-220FP package, featuring 14.5 mΩ RDS(on) at VGS = 10 V, 100% avalanche-rated operation, and qualified per AEC-Q101 for automotive use. It delivers high-efficiency synchronous rectification in DC-DC converters and motor control inverters.
For engineers reviewing the IPP50CN10NGXKSA1 datasheet, IPP50CN10NGXKSA1 pinout, IPP50CN10NGXKSA1 application, or IPP50CN10NGXKSA1 equivalent, key selection criteria include its 100 V VDSS, 50 A ID continuous rating, 14.5 mΩ on-resistance, 100% unclamped inductive switching capability, and AEC-Q101 qualification for under-hood automotive power stages.
Technical Context
This MOSFET employs Infineon's OptiMOS™ 5 technology, optimized for low gate charge (QG = 48 nC) and low output charge (QOSS = 105 nC), enabling high-frequency switching up to 500 kHz in hard-switched topologies. Its fast turn-on (ton = 17 ns) and turn-off (toff = 32 ns) times support precise PWM control in BLDC motor drives.
The device integrates a monolithic ESD protection diode and features a robust body diode with reverse recovery charge Qrr = 290 nC and trr = 52 ns - critical for minimizing commutation losses in half-bridge configurations used in automotive HVAC blowers and EPS systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - supports 48 V automotive battery systems with 2× transient margin for load dump events. |
| RDS(on) max @ VGS = 10 V | 14.5 mΩ - enables ≤1.5 W conduction loss at 50 A, reducing heatsink requirements in compact modules. |
| ID continuous @ TC = 25°C | 50 A - rated for sustained current in engine control unit (ECU) power stages without derating. |
| QG | 48 nC - allows efficient gate driving with standard 1 A peak drivers, minimizing driver IC cost and board space. |
| EAS | 420 mJ - guarantees single-pulse avalanche ruggedness for fault-tolerant operation in motor phase-legs. |
| tr/tf | 12 ns / 18 ns - supports clean edge transitions in 200–500 kHz SMPS designs, reducing EMI filter burden. |
| Qrr | 290 nC - lowers body-diode switching loss during freewheeling in synchronous buck converters. |
Pinout & Package
IPP50CN10NGXKSA1 is housed in a TO-220FP (Full-Pak) package: insulated plastic case with isolated drain tab, 2.5 mm creepage/clearance, vertical mounting orientation, and 1-layer copper pad (≥1 cm²) recommended for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main power output terminal | Electrically connected to metal tab; must be thermally coupled to heatsink and electrically isolated via insulating washer. |
| Source | Reference node for gate drive and current sensing | Low-inductance connection required for stable switching; ties to PCB ground plane near driver IC. |
| Gate | Control input for channel conduction | High-impedance node; requires RC snubber (10 Ω + 100 pF) to suppress ringing in >100 kHz applications. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood environments (−40°C to 175°C junction, 1000-cycle temperature cycling). |
| 100% UIS tested | Each unit screened for unclamped inductive switching energy ≥420 mJ - ensures field reliability in motor stall conditions. |
| Low QG/RDS(on) ratio | 3.3 nC/mΩ - optimizes trade-off between switching speed and conduction loss in 12–48 V DC systems. |
| Fast, soft body diode | trr = 52 ns with softness factor >1.2 - reduces voltage overshoot and EMI during commutation in half-bridges. |
| Isolated TO-220FP package | Drain tab insulation withstands 2.5 kV AC for 1 minute - eliminates need for isolating hardware in Class I safety designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel 100 V power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP55NF10 | RDS(on) = 18 mΩ @ 10 V; QG = 65 nC; no AEC-Q101 qualification | Not suitable for automotive under-hood use; acceptable for industrial 24 V motor drives only | Select only if AEC-Q101 is not required and thermal margin permits higher RDS(on). |
| IRF540NPBF | RDS(on) = 44 mΩ @ 10 V; QG = 71 nC; TO-220 non-isolated package | Limited to 20 A continuous; requires external isolation hardware and larger heatsink | Use only in cost-sensitive, non-automotive 24 V applications where efficiency >92% is not mandatory. |
Compared with STP55NF10 and IRF540NPBF, IPP50CN10NGXKSA1 provides superior conduction efficiency (24% lower RDS(on) vs. STP55NF10), automotive-grade reliability, and integrated isolation - making it the only viable choice for AEC-compliant 48 V traction auxiliary systems.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 175°C, and continuous operation at this temperature is permitted only when case temperature remains ≤110°C with adequate heatsinking. Derating begins linearly above TC = 25°C per the datasheet's thermal resistance curve (RthJC = 1.2 K/W). Thermal design must account for ambient, airflow, and PCB copper area.
Does IPP50CN10NGXKSA1 require a gate resistor for stability?
Yes - a 10 Ω series gate resistor is recommended to dampen parasitic oscillation caused by PCB trace inductance and MOSFET input capacitance. Without it, ringing exceeding 20 V peak-to-peak may occur at VGS edges, risking unintended turn-on or gate oxide stress during 350 kHz switching.
Can this MOSFET replace IPP50CN10N in existing designs?
No - IPP50CN10NGXKSA1 uses TO-220FP (isolated tab), whereas IPP50CN10N uses standard TO-220 (non-isolated tab). Mechanical mounting, thermal interface, and safety clearance must be revalidated. Electrical specs are identical, but isolation certification differs.
What is the typical gate threshold voltage range, and how does it affect drive compatibility?
VGS(th) is specified from 2.0 V to 4.0 V at ID = 250 µA. This range ensures reliable turn-on with 5 V logic-level drivers while preventing accidental activation from noise below 2 V. For robust 10 V gate drive, a minimum 8 V supply is recommended to maintain >95% RDS(on) spec margin across temperature.
