Product details

Overview

IPP65R050CFD7AAKSA1 from Infineon is a 650 V, 50 mΩ automotive-qualified Superjunction MOSFET in PG-TO220-3 package with integrated fast body diode, ultra-low Qrr (1.2 µC), RDS(on)×Qg FOM of 5.1 nC·Ω, and 1300 A/µs diF/dt capability-designed for ZVS phase-shift full-bridge and LLC resonant DC-DC converters in on-board chargers.

For engineers reviewing the IPP65R050CFD7AAKSA1 datasheet, IPP65R050CFD7AAKSA1 pinout, IPP65R050CFD7AAKSA1 application, or IPP65R050CFD7AAKSA1 equivalent, key selection criteria include avalanche-tested ruggedness (248 mJ EAS), 150 °C max junction temperature, 100% AEC-Q101 qualification, and optimized light-load efficiency via fast body diode recovery.

Technical Context

This CoolMOS™ CFD7A device implements charge-compensated superjunction architecture with field-stop layer and integrated fast-recovery body diode-enabling zero-voltage switching in high-frequency resonant topologies without external diode snubbing. Its dv/dt ruggedness (120 V/ns) and 1300 A/µs diF/dt support robust operation in bidirectional power flow stages.

Rated for 45 A continuous drain current at TC = 25 °C and 29 A at TC = 100 °C, it delivers 227 W power dissipation with 0.55 °C/W junction-to-case thermal resistance. Gate plateau voltage is fixed at 5.7 V, and total gate charge is 102 nC at VGS = 0–10 V, enabling predictable drive requirements in isolated gate driver designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPP65R041CFD7A	R_DS(on),max = 41 mΩ; Q_g = 115 nC; same package and AEC-Q101 qualification	Lower conduction loss but higher switching loss due to +13 nC Q_g; best suited for <200 kHz PFC where conduction dominates	Select when system prioritizes full-load efficiency over switching frequency scalability
IPW65R050CFD7XKSA1	Same R_DS(on) and Q_g, but in TO-247-3 package; R_thJC = 0.45 °C/W; no AEC-Q101 certification	Higher thermal performance but not qualified for automotive use; suitable for industrial UPS or solar inverters	Select for non-automotive applications requiring lower thermal resistance and higher pulse current (211 A)

Compared with IPP65R041CFD7A and IPW65R050CFD7XKSA1, IPP65R050CFD7AAKSA1 uniquely balances automotive qualification, thermal footprint, and resonant topology optimization-making it the only choice for AEC-Q101-compliant OBC primary switches operating above 200 kHz.

FAQ

Is IPP65R050CFD7AAKSA1 suitable for linear-mode operation?

No. Infineon explicitly advises against linear-mode operation for this device. The datasheet states "We do not recommend using the CoolMOS mentioned in this datasheet to operate in 'linear mode'" due to uncontrolled thermal runaway risk. Applications must remain within the SOA boundaries defined in Diagrams 2 and 3, with strict adherence to pulse-width and duty-cycle limits.

What is the maximum recommended gate resistor for reliable ZVS in LLC operation?

A gate resistor of 3.3 Ω is validated in the datasheet test conditions (td(on) = 34 ns, td(off) = 115 ns). Using RG > 5.6 Ω increases turn-off delay beyond ZVS window at >250 kHz, risking hard switching. For 300 kHz designs, Infineon recommends RG = 2.2–3.3 Ω with active Miller clamp to maintain consistent plateau timing.

Does the PG-TO220-3 package require thermal compound between tab and heatsink?

Yes. Although the metal tab is electrically connected to Drain, thermal interface material (TIM) is mandatory for effective heat transfer. Infineon specifies minimum mounting torque (60 Ncm) and recommends silicone-based thermal paste with ≤0.2 °C·in²/W thermal resistance to achieve the rated R_thJC = 0.55 °C/W.

How does cosmic radiation affect IPP65R050CFD7AAKSA1 in 475 V+ blocking applications?

For blocking voltages >475 V, cosmic radiation may induce single-event burnout (SEB). The datasheet mandates early design-phase evaluation of SEB susceptibility and direct engagement with Infineon's automotive support team to access radiation test reports and mitigation guidelines before finalizing system-level voltage derating.
