Product details
Overview
IPB65R660CFDATMA1 from Infineon Technologies is a 650 V, 6.0 A (TC = 100 °C) N-channel superjunction MOSFET in D²PAK (PG-TO263) package, featuring 0.66 Ω max RDS(on), 22 nC total gate charge, and ultra-fast body diode with 65 ns reverse recovery time. It delivers low conduction and switching losses for resonant-mode SMPS in industrial power supplies and telecom rectifiers.
For engineers reviewing the IPB65R660CFDATMA1 datasheet, IPB65R660CFDATMA1 pinout, IPB65R660CFDATMA1 application, or IPB65R660CFDATMA1 equivalent, key selection criteria include its 900 A/µs di/dt ruggedness, 2 Ω·K/W junction-to-case thermal resistance, and qualification for industrial-grade operation per JEDEC J-STD-20/JESD22.
Technical Context
This CoolMOS™ CFD2 device implements a superjunction structure optimized for high-voltage, high-efficiency resonant topologies such as LLC and ZVS-PWM converters. Its low Eoss (1.8 µJ @ 400 V) and reduced Qg × RDS(on) figure-of-merit enable fast switching with minimal voltage overshoot and reduced snubber losses.
The integrated body diode exhibits controlled reverse recovery with 0.2 µC Qrr, 4.5 A IRRM, and robust commutation capability up to 900 A/µs - critical for hard-switched and synchronous rectification stages where diode stress limits reliability.

FAQ
What is the maximum continuous drain current for IPB65R660CFDATMA1 at 100 °C case temperature?
The maximum continuous drain current is 3.8 A at TC = 100 °C, as specified in Table 2 of the Rev. 2.5 datasheet. This rating is thermally limited by the 2 °C/W junction-to-case resistance and 150 °C maximum junction temperature, not by package current-carrying capacity.
Does IPB65R660CFDATMA1 require a negative gate voltage for reliable turn-off?
No. The device has a gate threshold voltage range of 3.5–4.5 V and is fully controllable with 0–10 V gate drive. A negative gate voltage is not required; however, applying –5 V during off-state improves noise immunity in high-dv/dt environments per Infineon's application note AN2015-04.
Can IPB65R660CFDATMA1 replace older CoolMOS™ CFD1 devices in existing designs?
Yes - it is a direct drop-in replacement for CFD1 variants (e.g., IPB65R660CFD1) with identical pinout, RDS(on), and gate charge. Key improvements include 30% lower Eoss, faster trr, and enhanced di/dt ruggedness, enabling higher frequency operation without layout changes.
What is the recommended gate resistor value for 250 kHz LLC operation?
A 6.8 Ω gate resistor is validated in Infineon's reference design RDHP120 for 250 kHz LLC operation, balancing switching speed (ton/toff < 20 ns) and gate oscillation suppression. Lower values (<4.7 Ω) increase EMI risk; higher values (>10 Ω) degrade ZVS margin above 200 kHz.
