Infineon Technologies IPB60R280P6ATMA1

Overview

IPB60R280P6 from Infineon Technologies is a 600 V, 280 mΩ superjunction N-channel power MOSFET in D²PAK (TO-263) package, optimized for high-efficiency PFC and hard-switching PWM stages. It delivers 13.8 A continuous drain current at 25°C, 26 nC total gate charge, and 3.5 µJ output energy at 400 V - enabling compact, cooler-running server PSUs and industrial adapters.

For engineers reviewing the IPB60R280P6 datasheet, IPB60R280P6 pinout, IPB60R280P6 application, or IPB60R280P6 equivalent, key selection criteria include R_DS(on) vs. temperature stability, dv/dt ruggedness (100 V/ns), body diode commutation capability (500 A/µs), and thermal resistance (1.2 °C/W junction-to-case).

Technical Context

This CoolMOS™ P6 device implements a charge-compensated superjunction structure with optimized cell pitch and epitaxial doping profile to simultaneously reduce conduction loss (R_DS(on) = 280 mΩ max @ 150°C) and switching loss (E_oss = 3.5 µJ @ 400 V). Its gate threshold voltage (4.0 V typ) and plateau voltage (6.1 V) support robust 12–15 V gate drive without overdrive risk.

The MOSFET features enhanced avalanche ruggedness (E_AS = 285 mJ) and high di/dt capability (500 A/µs), making it suitable for discontinuous conduction mode (DCM) and transition-mode (TM) PFC controllers where fast body diode recovery and high commutation stress are present.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous drain current for IPB60R280P6 at 100°C case temperature?

The maximum continuous drain current is 8.8 A at T_C = 100°C, as specified in Table 2 of the Rev. 2.2 datasheet. This value accounts for thermal derating due to junction-to-case thermal resistance (1.2 °C/W) and maximum junction temperature (150°C), ensuring safe operation under sustained load conditions.

Does IPB60R280P6 require a gate resistor for stable operation?

Yes - a gate resistor of 3.4 Ω is used in the datasheet's dynamic test conditions (Table 7), and Infineon recommends 2.2–10 Ω depending on switching speed and EMI requirements. Lower values improve switching speed but increase gate driver stress and ringing risk; higher values suppress oscillation at the cost of increased switching loss.

Can IPB60R280P6 replace older CoolMOS™ P5 devices in existing designs?

Yes - IPB60R280P6 is a direct drop-in replacement for IPB60R280P5 in D²PAK, offering identical pinout, voltage rating, and R_DS(on), plus improved E_oss (−15%), Q_g (−12%), and dv/dt ruggedness (+25 V/ns). No layout or drive circuit changes are required for most PFC and PWM applications.

Is the drain tab of IPB60R280P6 electrically isolated from the PCB substrate?

No - the drain is internally connected to the exposed copper tab, which must be either soldered directly to a drain-copper pour (electrically active) or mounted on an isolated heatsink using insulating thermal pads. Electrical isolation between drain and PCB ground is achieved only via layout separation or insulated mounting hardware.
