Infineon Technologies IPB65R095C7ATMA1

Overview

IPB65R095C7ATMA1 from Infineon Technologies is a 650 V, 95 mΩ R_DS(on) superjunction MOSFET in D²PAK (TO-263) package, optimized for high-frequency hard-switching and PFC stages. It delivers 45 nC total gate charge, 5.5 µJ E_oss at 400 V, and 60 A/µs body diode di/dt, enabling high-efficiency server power supplies and telecom rectifiers.

For engineers reviewing the IPB65R095C7ATMA1 datasheet, IPB65R095C7ATMA1 pinout, IPB65R095C7ATMA1 application, or IPB65R095C7ATMA1 equivalent, key selection criteria include its 0.98 °C/W R_thJC, 100 V/ns dv/dt ruggedness, and industrial-grade JEDEC qualification-critical for reliable operation in high-density AC-DC converters.

Technical Context

This CoolMOS™ C7 device implements a charge-compensated superjunction structure with trench-gate design, delivering best-in-class R_DS(on) × Q_g and R_DS(on) × E_oss figures of merit. Its 5.4 V gate plateau voltage and low 0.9 Ω gate resistance support robust, low-loss switching control.

The MOSFET integrates a fast-recovery body diode (t_rr = 800 ns, Q_rr = 9 µC) and supports 100 V/ns dv/dt without spurious turn-on. Thermal performance is defined by 0.98 °C/W junction-to-case resistance and 35–45 °C/W junction-to-ambient on standard FR4 PCB layouts.

FAQ

What is the maximum continuous drain current for IPB65R095C7ATMA1 at 100°C case temperature?

The maximum continuous drain current is 15 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.0 datasheet. This rating reflects thermal derating due to junction-to-case thermal resistance (0.98 °C/W) and ensures safe operation within the 150°C maximum junction temperature limit under sustained load.

Does IPB65R095C7ATMA1 require a gate resistor for stability in hard-switching applications?

Yes-a gate resistor (typically 5–10 Ω) is recommended to dampen ringing and control dV/dt during turn-on/turn-off. The device's 0.9 Ω internal gate resistance and low C_iss (2140 pF) make external gate resistance essential for EMI suppression and preventing oscillation when driven by standard MOSFET drivers.

Can IPB65R095C7ATMA1 be paralleled with identical units in high-current PFC designs?

Yes, but with specific layout and gate drive precautions: use individual ferrite beads on each gate line or separate totem-pole drivers to suppress circulating currents. The datasheet explicitly recommends this approach to ensure balanced current sharing and avoid thermal runaway in parallel configurations.

Is the drain tab of IPB65R095C7ATMA1 electrically isolated from the PCB mounting pad?

No-the drain tab (Pin 2) is electrically connected to the drain terminal and must be isolated from the PCB ground plane using insulating thermal pads or dielectric coatings if mounted to a common heatsink. Direct soldering to copper requires careful clearance design to prevent short circuits in high-voltage topologies.
