Product details

Overview

IPS70R2K0CEAKMA1 from Infineon Technologies is a 700 V, 2.0 Ω (max) R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO251 (IPAK SL) package, with drain-connected tab, gate on pin 1, source on pin 3. It delivers 4 A continuous drain current at T_C = 25°C, 7.8 nC total gate charge, and 0.85 µJ output energy at 400 V - optimized for QR flyback converters in low-power mobile chargers and power tool adapters.

For engineers reviewing the IPS70R2K0CEAKMA1 datasheet, IPS70R2K0CEAKMA1 pinout, IPS70R2K0CEAKMA1 application, or IPS70R2K0CEAKMA1 equivalent, key selection factors include its 700 V blocking rating, 2.0 Ω R_DS(on) at 150°C, commutation ruggedness (dv/dt = 50 V/ns), E_oss-optimized switching, and qualification for standard-grade consumer and lighting applications.

Technical Context

This CoolMOS™ CE device implements a superjunction structure enabling high-voltage operation with significantly reduced R_DS(on) × Q_g figure-of-merit versus planar MOSFETs. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V typical) support robust drive with standard 10–13 V gate drivers.

The MOSFET integrates an intrinsic fast-recovery body diode (t_rr = 187 ns, Q_rr = 0.8 µC at 400 V), rated for repetitive avalanche (E_AR = 0.07 mJ) and single-pulse avalanche (E_AS = 11 mJ), making it suitable for discontinuous conduction mode (DCM) QR flyback topologies where diode commutation stress is critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	700 V - supports primary-side switching in universal-input (90–264 V_AC) QR flyback designs up to 400 V DC bus.
R_DS(on) max	2.00 Ω @ T_j = 150°C - enables low conduction loss in compact, thermally constrained chargers.
Q_g typ	7.8 nC - reduces gate drive power and simplifies driver design for 65–100 kHz QR controllers.
E_oss @ 400 V	0.85 µJ - minimizes turn-on switching loss in high-frequency QR operation.
I_D cont	4 A @ T_C = 25°C - supports output power up to ~25 W in cost-sensitive low-power adapters.
t_rr	187 ns - limits reverse recovery ringing and EMI in DCM flyback snubberless designs.
R_thJC	2.95 °C/W - allows direct heatsinking via drain-connected tab for thermal management in IPAK SL layout.

Pinout & Package

IPS70R2K0CEAKMA1 uses the PG-TO251 (IPAK SL) surface-mount package with exposed drain tab for thermal conduction. Pin 1 is Gate, Pin 2 is Drain (connected to metal tab), Pin 3 is Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; accepts 10–13 V logic-level drive; 6.5 Ω internal gate resistance aids EMI control.
Pin 2 / Tab	Drain	High-voltage power input node; tab provides low-thermal-resistance path to heatsink or PCB copper pour.
Pin 3	Source	Power return and reference for gate drive; connects to primary ground in flyback circuits.

Key Features

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
IPP60R190CE	600 V rating, 1.9 Ω R_DS(on), same CoolMOS™ CE platform and IPAK SL package.	Limited to 265 V_AC max input; unsuitable for 305 V_AC surge or 400 V DC bus designs.	Select only when system input is strictly limited to ≤265 V_AC and lower R_DS(on) justifies voltage derating.
IPA60R190CE	Same 600 V/1.9 Ω specs as IPP60R190CE but in PG-TO220FP (full-pack) with insulated case.	Requires isolation hardware and larger footprint; higher R_thJA (62 °C/W vs. 2.95 °C/W junction-to-case).	Choose only if mechanical mounting constraints require through-hole insulation or forced-air cooling is unavailable.

Compared with IPP60R190CE and IPA60R190CE, IPS70R2K0CEAKMA1 provides essential 700 V headroom for global universal-input compliance and superior thermal performance via its drain-tab thermal path - critical for sealed, fanless adapter enclosures.

FAQ

What is the maximum recommended gate drive voltage for IPS70R2K0CEAKMA1?

The absolute maximum gate-source voltage is ±30 V for dynamic (AC) conditions and ±20 V for static conditions. For reliable operation, gate drive should be clamped to 10–13 V using a dedicated gate driver IC or resistor-Zener network. Exceeding 13 V does not improve R_DS(on) significantly but increases gate oxide stress and ESD risk.

Can IPS70R2K0CEAKMA1 replace older CoolMOS™ C3 or C7 parts in existing designs?

No direct drop-in replacement is guaranteed. While all belong to Infineon's CoolMOS™ family, CE has different gate charge profile (Q_gd/Q_g ratio), threshold voltage distribution, and E_oss behavior. Layout and gate driver tuning - especially RG value and snubber placement - must be re-validated per the CE datasheet to ensure stable QR timing and low EMI.

Is the drain tab electrically isolated in the PG-TO251 package?

No. The metal tab is internally connected to Pin 2 (Drain) and is not electrically isolated. When mounted on a heatsink or copper pour, that surface must be treated as live high-voltage potential. Insulating pads or ceramic washers are required if the heatsink is grounded or shared with low-voltage circuitry.

Does IPS70R2K0CEAKMA1 support hard-switched PFC or LLC resonant topologies?

It is not optimized for either. Its 700 V rating and E_oss make it suitable for QR flyback, but its Q_g and C_oss values are not tuned for zero-voltage switching in LLC, nor does it meet the SOA or avalanche energy requirements for continuous conduction mode (CCM) PFC. Use dedicated PFC or resonant MOSFETs instead.
