Infineon Technologies IPP65R065C7XKSA1

Overview

IPP65R065C7XKSA1 from Infineon Technologies is a 650 V, 65 mΩ superjunction N-channel power MOSFET in TO-220 package, optimized for high-frequency hard-switching and PFC stages. It delivers 145 A pulsed drain current, 64 nC total gate charge, and 8 µJ output energy at 400 V-enabling compact, high-efficiency server and telecom power supplies.

For engineers reviewing the IPP65R065C7XKSA1 datasheet, IPP65R065C7XKSA1 pinout, IPP65R065C7XKSA1 application, or IPP65R065C7XKSA1 equivalent, key selection criteria include R_DS(on) × Q_g figure-of-merit, dv/dt ruggedness (100 V/ns), body diode dI/dt capability (60 A/µs), and industrial-grade JEDEC qualification.

Technical Context

This CoolMOS™ C7 device employs superjunction architecture to achieve low R_DS(on) (65 mΩ max at 10 V, 150 °C) while maintaining fast switching with 17 ns turn-on delay and 72 ns turn-off delay under 400 V, 17.1 A conditions. Its 3020 pF input capacitance and 100 pF energy-related output capacitance support high-frequency operation up to 300 kHz in continuous conduction mode PFC.

The MOSFET integrates a robust body diode with 800 ns reverse recovery time and 10 µC Q_rr, enabling reliable operation in bridge configurations without external snubbers. Gate plateau voltage of 5.4 V ensures stable Miller region control during hard switching.

FAQ

What is the maximum continuous drain current for IPP65R065C7XKSA1 at 100 °C case temperature?

The maximum continuous drain current is 21 A at T_C = 100 °C, as specified in Table 2 of the Rev. 2.0 datasheet. This rating accounts for thermal derating due to junction-to-case resistance (0.73 °C/W) and maximum junction temperature (150 °C), ensuring safe operation without forced cooling in enclosed enclosures.

Does IPP65R065C7XKSA1 require a gate resistor for stability in hard-switching applications?

A gate resistor of 5.3 Ω is used in the datasheet's dynamic test conditions (Table 5), but the device's 100 V/ns dv/dt ruggedness allows stable operation with resistors as low as 2.2 Ω in 400 V bus applications. Lower values improve switching speed but must be balanced against gate oscillation risk on long PCB traces.

Can IPP65R065C7XKSA1 be paralleled with identical units?

Yes-parallel operation is supported per datasheet note, but requires individual ferrite beads on each gate line or separate totem-pole drivers to suppress circulating currents. Matching R_DS(on) tolerance (±20%) and thermal layout symmetry are essential to ensure current sharing within ±10% imbalance.

Is the TO-220 tab electrically isolated in IPP65R065C7XKSA1?

No-the metal tab is internally connected to the Drain terminal, as confirmed by "tab Drain Pin 2" in the package description. Electrical isolation requires insulating hardware (e.g., silicone pads, mica washers) and non-conductive mounting screws when attaching to grounded heatsinks.
