Product details
Overview
IPW65R190CFDFKSA2 from Infineon Technologies is a 650 V, 17.5 A (TC = 25°C) superjunction N-channel power MOSFET in TO-247 package, featuring RDS(on) = 0.19 Ω max, Qg = 68 nC typ, and ultra-fast body diode with trr = 120 ns - engineered for high-efficiency resonant switching in server SMPS and telecom PFC stages.
For engineers reviewing the IPW65R190CFDFKSA2 datasheet, IPW65R190CFDFKSA2 pinout, IPW65R190CFDFKSA2 application, or IPW65R190CFDFKSA2 equivalent, key selection criteria include commutation ruggedness (di/dt = 900 A/µs), Eoss = 5.7 µJ at 400 V, low FOM (RDS(on) × Qg), and industrial-grade JEDEC qualification.
Technical Context
This CoolMOS™ CFD2 device implements a charge-compensated superjunction structure enabling simultaneous reduction of conduction and switching losses. Its optimized gate charge profile (Qgs = 12 nC, Qgd = 37 nC) and low Coss,eff = 70 pF support ZVS/ZCS operation in LLC and phase-shifted full-bridge topologies.
The integrated ultra-fast body diode delivers robust reverse recovery performance (Qrr = 0.5 µC, Irrm = 7.5 A) without external snubbers, while dv/dt ruggedness of 50 V/ns ensures stable operation in high-noise high-side configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 650 V - supports 400 V DC bus with 1.6× safety margin for telecom/server applications |
| RDS(on),max | 0.19 Ω - enables <1.5 W conduction loss at 11 A continuous drain current |
| Qg,typ | 68 nC - determines gate drive power requirement (~0.85 mW per MHz at 13 V drive) |
| Eoss@400V | 5.7 µJ - directly reduces turn-on switching loss in hard-switched and resonant converters |
| trr | 120 ns - allows reliable operation up to 300 kHz with minimal diode-induced voltage overshoot |
| di/dt rating | 900 A/µs - sustains fast current transitions during LLC resonant tank commutation |
| PD@TC=25°C | 151 W - supports high-power density designs with active heatsinking |
Pinout & Package
IPW65R190CFDFKSA2 uses the standard TO-247 package (PG-TO247), with isolated mounting hole and screw-compatible mechanical interface. Thermal resistance RthJC = 0.83 °C/W enables efficient heat transfer to heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control input | Low-impedance gate terminal requiring ≤3.4 Ω series resistance for stable switching; threshold VGS(th) = 3.5–4.5 V |
| Pin 2 (Drain) | High-voltage power output | Connected to primary-side HV rail; rated for 650 V blocking and avalanche energy EAS = 484 mJ |
| Pin 3 (Source) | Power return / reference | Common node for gate drive return and current sensing; ties to PCB ground plane for low-inductance layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast body diode | trr = 120 ns and Qrr = 0.5 µC reduce dead-time losses and eliminate need for external anti-parallel SiC diodes in soft-switching PFC |
| High commutation ruggedness | di/dt = 900 A/µs and EAR = 0.70 mJ enable reliable operation under asymmetric LLC resonant current reversal |
| Low figure-of-merit | RDS(on) × Qg = 12.9 Ω·nC - minimizes combined conduction + gate-drive loss in 100–300 kHz SMPS |
| Industrial qualification | Qualified per JEDEC J-STD-020 (MSL 1) and JESD22-A108 (150°C operating temp) for long-term reliability in uncontrolled environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPW65R190CFD | Same die, identical electrical specs; differs only in packaging suffix (no 'FKSA2' marking) | No functional difference; FKSA2 denotes specific tape-and-reel and traceability configuration | Select IPW65R190CFDFKSA2 for production traceability and AEC-Q200-aligned logistics |
| IPW65R190CFD7 | CFD7 generation: lower Qg (52 nC), higher RDS(on) (0.21 Ω), improved Eoss (4.2 µJ) | Better suited for >500 kHz operation but less optimal for 100–300 kHz high-current PFC | Choose CFD7 only when prioritizing ultra-high-frequency switching over conduction loss at 11–17 A loads |
Compared with IPW65R190CFD and IPW65R190CFD7, the IPW65R190CFDFKSA2 offers the best balance of low RDS(on), moderate Qg, and proven ruggedness for industrial 100–300 kHz resonant converters - making it the preferred choice where thermal margin and diode reliability dominate design constraints.

FAQ
What is the maximum continuous drain current for IPW65R190CFDFKSA2 at 100°C case temperature?
The maximum continuous drain current is 11.0 A at TC = 100°C, as specified in Table 2 of the Rev. 2.7 datasheet. This value is limited by thermal constraints and assumes proper heatsinking with RthJC = 0.83 °C/W and ambient airflow per JEDEC test conditions.
Does IPW65R190CFDFKSA2 require a negative gate voltage for reliable turn-off?
No - the device operates reliably with 0 V to 10 V gate drive and has no requirement for negative turn-off bias. Its gate threshold voltage range (3.5–4.5 V) and low gate leakage (<100 nA) ensure stable enhancement-mode operation using standard 12 V gate drivers.
Can IPW65R190CFDFKSA2 replace standard 650 V MOSFETs in existing PFC designs without layout changes?
Yes - it uses the industry-standard TO-247 footprint and pinout (drain=pin2, gate=pin1, source=pin3), and its lower Qg and Eoss typically improve efficiency without requiring PCB modifications, though gate drive strength should be verified for 68 nC total charge.
Is the body diode in IPW65R190CFDFKSA2 suitable for synchronous rectification?
No - this is a standard superjunction MOSFET with an integrated fast body diode optimized for commutation, not a dedicated synchronous rectifier. It lacks the low VF and bidirectional conduction characteristics required for SR operation; use discrete Schottky or GaN devices instead.
