Product details

Overview

IPA65R280E6 from Infineon Technologies is a 650 V, 0.28 Ω R_DS(on) CoolMOS™ E6 superjunction power MOSFET in TO-220 FullPAK package, optimized for high-efficiency SMPS in adapters and industrial power supplies. It delivers 45 nC gate charge, 3.7 µJ output switching energy at 400 V, and supports 39 A pulsed drain current with 500 A/µs body diode commutation speed.

For engineers reviewing the IPA65R280E6 datasheet, IPA65R280E6 pinout, IPA65R280E6 application, or IPA65R280E6 equivalent, key selection criteria include its low R_DS(on)×Q_g figure-of-merit, high dv/dt ruggedness (50 V/ns), and thermal resistance of 3.9 °C/W (junction-to-case), critical for compact, thermally constrained adapter and server PSU designs.

Technical Context

This device implements Infineon's 6th-generation superjunction architecture, enabling fast switching with reduced E_oss and minimized Miller capacitance. Its gate plateau voltage of 5.5 V and 7.0 Ω intrinsic gate resistance support stable drive under high-frequency operation up to 100 kHz in hard-switched PFC and LLC resonant converters.

The body diode exhibits 0.9 V forward voltage at 6.6 A and 310 ns reverse recovery time, with 3.6 µC Q_rr and 21 A peak reverse recovery current-enabling robust synchronous rectification and ZVS-assisted topologies without external snubbing in mid-power applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW65R280E6	TO-247 package, R_thJC = 1.2 °C/W (vs. 3.9 °C/W), same R_DS(on) and Q_g	Better thermal performance in forced-air cooled industrial PSUs; requires larger footprint and mechanical mounting	Select when junction temperature must stay below 125 °C under 104 W dissipation at 100 °C ambient
IPP65R280E6	TO-220 (non-FullPAK), R_thJC = 1.2 °C/W, identical electrical specs but no insulated source tab	Suitable for cost-sensitive open-frame supplies where creepage distance is less critical	Choose when isolation between drain and heatsink is managed externally and PCB space permits standard TO-220 layout

Compared with IPW65R280E6 and IPP65R280E6, IPA65R280E6 trades higher thermal resistance for enhanced safety isolation and compact PCB integration-ideal for enclosed, double-insulated adapter designs where creepage and footprint are prioritized over absolute thermal headroom.

FAQ

What is the maximum continuous drain current for IPA65R280E6 at 100 °C case temperature?

The maximum continuous drain current is 8.7 A at T_C = 100 °C, limited by junction temperature (T_j,max = 150 °C) and thermal resistance of 3.9 °C/W. This value assumes adequate PCB copper area and no additional heatsink; derating applies above 100 °C ambient.

Can IPA65R280E6 be used in parallel configurations?

Yes, but Infineon recommends using ferrite beads on each gate line or separate totem-pole drivers to balance dynamic current sharing. The device's positive temperature coefficient for R_DS(on) aids static current sharing, though mismatched layout inductance can cause imbalance at high di/dt.

Does IPA65R280E6 require a negative gate voltage for reliable turn-off?

No-its gate threshold voltage is 2.5–3.5 V, and it is fully specified for 0 V to +10 V gate drive. A negative gate bias is not required, though −5 V may be used to improve noise immunity in high-dv/dt environments per application note AN2015-04.

What is the recommended gate resistor value for 100 kHz PFC operation?

A 3.4 Ω gate resistor is validated in the datasheet for 100 kHz operation with 13 V drive and 6.6 A current (Table 20). For lower EMI, increase to 5.6 Ω; for faster switching, reduce to 2.2 Ω-but verify gate drive capability and oscillation margin with actual layout parasitics.
