Product details

Overview

IPS70R1K4CEAKMA1 from Infineon Technologies is a 700 V, 1.4 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO251 (IPAK) package, optimized for high-efficiency, cost-sensitive offline SMPS in lighting and adapter applications. It delivers 5.4 A continuous drain current at T_C = 25°C, 10.5 nC total gate charge, and 1.15 µJ output energy at 400 V.

For engineers reviewing the IPS70R1K4CEAKMA1 datasheet, IPS70R1K4CEAKMA1 pinout, IPS70R1K4CEAKMA1 application, or IPS70R1K4CEAKMA1 equivalent, key selection criteria include its 700 V blocking voltage, low E_oss, high commutation ruggedness (dv/dt = 50 V/ns), and compatibility with standard gate drivers in flyback and PFC stages.

Technical Context

This CoolMOS™ CE device implements a superjunction structure enabling significantly lower R_DS(on) × Q_g figure-of-merit than planar MOSFETs while maintaining robust hard-switching capability. Its 5.4 A I_D rating and 2.37 °C/W R_thJC support thermally constrained designs in compact adapters.

The MOSFET features a fast intrinsic body diode with t_rr = 200 ns and Q_rr = 0.9 µC at 400 V, enabling reliable discontinuous conduction mode (DCM) operation in flyback converters without external snubbing. Gate plateau voltage is 5.4 V, ensuring stable turn-on under typical 12 V gate drive.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - supports universal AC input (85–265 V_AC) with margin in offline flyback and PFC topologies
R_DS(on), max	1.40 Ω @ T_j = 150°C - enables low conduction loss in 5–10 W lighting drivers
Q_g, typ	10.5 nC - reduces gate drive power and allows use of low-cost 12 V controllers
E_oss @ 400 V	1.15 µJ - lowers switching loss in high-frequency (60–130 kHz) flyback designs
I_D, cont	5.4 A @ T_C = 25°C - supports up to ~15 W output in thermally managed adapters
dv/dt ruggedness	50 V/ns - ensures reliable operation in high-noise, unshielded consumer power supplies
t_rr	200 ns - minimizes reverse recovery loss during hard commutation in DCM flyback

Pinout & Package

IPS70R1K4CEAKMA1 is housed in PG-TO251 (IPAK) package with exposed drain tab for thermal enhancement. The package uses standard leadframe geometry compatible with automated SMT assembly and manual rework.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control terminal	Receives gate drive signal; requires ≤10.2 Ω series resistance to limit ringing and ensure controlled dv/dt
Pin 2 (Drain) + Tab	High-voltage power terminal	Connected to primary-side high-voltage rail; tab provides low-thermal-resistance path to PCB copper pour
Pin 3 (Source)	Reference and return path	Serves as local ground reference for gate driver; must be routed with minimal inductance to avoid shoot-through risk

Key Features

Feature	Design Value
Superjunction architecture	Delivers 1.4 Ω R_DS(on) at 700 V, reducing conduction loss by >30% vs. comparable planar MOSFETs
Low E_oss (1.15 µJ @ 400 V)	Enables higher switching frequencies without proportional efficiency penalty in flyback converters
High commutation ruggedness (50 V/ns)	Eliminates need for external dv/dt snubbers in cost-sensitive indoor lighting ballasts
Pb-free plating & halogen-free mold compound	Meets RoHS 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3)

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
IPD70R1K4CE	Same die, PG-TO252 (DPAK) package; R_thJC = 2.37 °C/W identical, but larger footprint and higher thermal mass	Better suited for manual assembly or prototyping; less suitable for dense SMT layouts	Select when board space permits and thermal interface to heatsink is via screw-mount rather than solder pad
IPP60R1K4C6	600 V rating, same R_DS(on) and Q_g; lower E_oss (0.95 µJ), but reduced voltage margin for universal AC input	Acceptable only in fixed-input (e.g., 230 V_AC-only) lighting systems with derated design	Choose only if system input range is restricted and 100 V safety margin is acceptable per IEC 61347-1

Compared with IPD70R1K4CE and IPP60R1K4C6, IPS70R1K4CEAKMA1 offers optimal balance of 700 V rating, IPAK form factor, and proven ruggedness in cost-driven lighting and adapter designs-making it the preferred choice where board area, manufacturability, and universal input compliance are jointly critical.

FAQ

What is the maximum recommended gate resistor value for IPS70R1K4CEAKMA1 in a 100 kHz flyback design?

The datasheet specifies 10.2 Ω for characterization at 400 V and 1.5 A. For 100 kHz operation, a 10–15 Ω non-inductive resistor is recommended to balance switching speed (minimizing t_r/t_f) and gate ring suppression. Values above 22 Ω increase switching loss disproportionately without improving reliability.

Does IPS70R1K4CEAKMA1 require a negative gate turn-off voltage?

No. The device is rated for ±30 V dynamic gate-source voltage and operates reliably with 0 V to +12 V or +15 V gate drive. Negative turn-off is not required; however, a small negative bias (–2 V to –5 V) may improve noise immunity in high-dv/dt environments without affecting lifetime.

Can IPS70R1K4CEAKMA1 replace older CoolMOS™ C3 devices in existing designs?

Yes-IPS70R1K4CEAKMA1 is a direct drop-in replacement for IPD70R1K4C3 in PG-TO252 and IPS70R1K4C3 in PG-TO251. Electrical parameters (R_DS(on), Q_g, E_oss) are tighter, and dv/dt ruggedness is improved from 40 V/ns to 50 V/ns, enhancing robustness without layout changes.

Is the drain tab electrically isolated from the PCB copper pour in IPS70R1K4CEAKMA1?

No-the drain tab is internally connected to Pin 2 (Drain) and must be soldered to a high-voltage copper pour. Thermal vias beneath the tab must be placed only in non-isolated regions; isolation creepage/clearance rules apply between the tab and any low-voltage traces or planes on adjacent layers.
