Product details

Overview

IPS65R400CEAKMA1 from Infineon Technologies is a 650 V, 400 mΩ superjunction N-channel power MOSFET in PG-TO251 (IPAK) package, optimized for high-efficiency hard-switching and resonant PFC and PWM stages. It delivers 15.1 A continuous drain current at T_C = 25°C, 39 nC total gate charge, and 2.8 µJ output switching energy at 400 V - enabling compact, cooler-running AC/DC adapters and indoor LED drivers.

For engineers reviewing the IPS65R400CEAKMA1 datasheet, IPS65R400CEAKMA1 pinout, IPS65R400CEAKMA1 application, or IPS65R400CEAKMA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, E_oss-driven light-load efficiency, commutation ruggedness (500 A/µs di/dt), and gate drive simplicity with 5.5 V plateau voltage and JEDEC-qualified Pb-free construction.

Technical Context

This CoolMOS™ CE-series device implements a superjunction cell structure to achieve ultra-low figure-of-merit (R_DS(on) × Q_g = 15.6 Ω·nC typ) while maintaining robust avalanche capability (215 mJ single-pulse E_AS) and high dv/dt immunity (50 V/ns). Its 710 pF input capacitance and 41 pF output capacitance support fast, low-loss switching up to 100 kHz in continuous conduction mode PFC.

The integrated body diode features 280 ns reverse recovery time and 2.8 µC Q_rr at 400 V, enabling reliable operation in bridge-leg configurations without external snubbers. Gate threshold voltage is tightly distributed (2.5–3.5 V), ensuring stable turn-on across temperature and reducing risk of spurious conduction during high-noise switching events.

Pin 3 (Source)	Reference node & return path	Serves as local ground reference for gate driver; carries full switched current and diode recovery current

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPD65R400CE	Same die, TO-252 (DPAK) package; 1.25 °C/W R_thJC vs. 1.06 °C/W	Better suited for wave-soldered board-level assembly; lower thermal performance in SMT-only layouts	Select when DPAK footprint is fixed and thermal margin ≥15°C is available
IPP65R400CFD7	CE+ generation with faster diode (150 ns trr), 35 nC Q_g, same R_DS(on)	Enables higher-frequency ZVS in LLC; requires tighter gate drive timing control	Select for new designs targeting >200 kHz operation and improved light-load efficiency

Compared with IPD65R400CE, IPS65R400CEAKMA1 offers superior thermal resistance and SMT compatibility; versus IPP65R400CFD7, it trades slightly slower diode recovery for broader gate drive tolerance and proven field reliability in cost-sensitive adapters and lighting.

FAQ

What is the maximum recommended gate resistor value for IPS65R400CEAKMA1 in a 100 kHz PFC application?

A 4.9 Ω gate resistor is validated in the datasheet for 400 V bus operation at 100 kHz, delivering 10 ns turn-on delay and 7 ns rise time. Values above 10 Ω increase switching losses disproportionately due to extended Miller plateau duration; below 2.2 Ω risks gate oscillation without ferrite bead damping.

Does IPS65R400CEAKMA1 require a gate driver with negative turn-off capability?

No - its 3.5 V maximum gate threshold voltage and 5.5 V gate plateau ensure reliable turn-off with 0 V gate drive. Negative turn-off is unnecessary unless operating in high-noise environments with >20 V/ns common-mode transients, where a –2 V clamp may improve noise immunity.

Can IPS65R400CEAKMA1 be paralleled for higher current handling?

Yes, but only with gate ferrite beads (600 Ω @ 100 MHz) on each device and matched PCB trace lengths. Parallel operation increases conduction loss by <5% per additional unit, but mismatched R_DS(on) temperature coefficients require thermal coupling via shared heatsink to prevent current hogging.

Is the body diode suitable for synchronous rectification in a flyback converter?

No - its 280 ns reverse recovery time and 17 A peak recovery current make it unsuitable for SR operation above 50 kHz. It is designed for freewheeling and PFC boost diode replacement only; dedicated SR controllers require MOSFETs with <50 ns trr and optimized Q_rr/I_F ratio.
