Product details

Overview

IPSA70R1K4CEAKMA1 from Infineon Technologies is a 700 V, 1.4 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO251 (IPAK-short lead) package with ISO-standoff drain pin, designed for high-efficiency offline SMPS in adapter, LCD/PDP TV, and indoor lighting applications. It delivers 5.4 A continuous drain current, 10.5 nC total gate charge, and 1.15 µJ output switching energy at 400 V.

For engineers reviewing the IPSA70R1K4CEAKMA1 datasheet, IPSA70R1K4CEAKMA1 pinout, IPSA70R1K4CEAKMA1 application, or IPSA70R1K4CEAKMA1 equivalent, key selection criteria include its 700 V blocking voltage, low FOM (R_DS(on) × Q_g), high commutation ruggedness (dv/dt = 50 V/ns), and ISO-standoff isolation for enhanced creepage in compact AC/DC designs.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure optimized for cost-sensitive, high-efficiency consumer and lighting power supplies. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V) support standard 10–13 V gate drive, while low E_oss (1.15 µJ) and fast switching (t_r = 5.9 ns, t_f = 18.2 ns) reduce hard-switching losses in quasi-resonant and DCM flyback topologies.

The integrated body diode features 200 ns reverse recovery time and 0.9 µC Q_rr, enabling reliable operation in discontinuous conduction mode without external snubbing. Thermal resistance R_thJC = 2.37 °C/W ensures efficient heat transfer to the PCB via the isolated drain tab under 53 W P_tot at T_C = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	700 V - supports universal AC input (85–265 VAC) with sufficient margin for surge and ringing in offline converters
R_DS(on) max @ 150°C	1.40 Ω - enables low conduction loss at full load and elevated junction temperature in enclosed lighting fixtures
Q_g typ	10.5 nC - reduces gate driver power requirement and simplifies 10–13 V gate drive design for cost-sensitive controllers
E_oss @ 400 V	1.15 µJ - minimizes turn-on loss in high-frequency quasi-resonant flyback designs operating up to 100 kHz
dv/dt ruggedness	50 V/ns - ensures robustness against parasitic oscillation and false triggering in high-noise SMPS environments
R_thJC	2.37 °C/W - allows direct thermal coupling to copper pour on PCB, eliminating need for heatsink in ≤30 W adapters

Pinout & Package

IPSA70R1K4CEAKMA1 uses the PG-TO251 (IPAK-short lead) package with ISO-standoff drain pin (Pin 2), gate on tab (Pin 1), and source on lead (Pin 3). The isolated drain pad provides reinforced creepage for safety-critical AC/DC isolation barriers.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Tab)	Gate	Exposed metal tab serves as gate connection-requires insulated mounting or non-conductive thermal interface to avoid shorting
Pin 2	Drain (ISO-standoff)	Lead-mounted drain terminal with internal isolation standoff-enables ≥4 mm creepage across PCB without slotting
Pin 3	Source	Standard leaded source connection-used for Kelvin sensing or low-inductance return path in high-di/dt layouts

Key Features

Feature	Design Value
Superjunction architecture	Enables 700 V rating with R_DS(on) × Q_g figure-of-merit 30% lower than planar MOSFETs of same voltage class
ISO-standoff drain pin	Provides certified creepage distance without PCB cutouts-reduces layout complexity and manufacturing cost in Class II adapters
High commutation ruggedness	Withstands 50 V/ns dv/dt stress during hard switching-eliminates need for gate resistors >10 Ω in typical flyback designs
Pb-free & halogen-free	Meets RoHS 2011/65/EU and JEDEC J-STD-020 reflow profile-supports lead-free assembly in high-volume lighting production

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
IPD70R1K4CE	Dual-source TO-251 variant with identical R_DS(on), Q_g, and E_oss; same die, different marking and test flow	No change in layout or thermal design-direct replacement in existing IPAK footprints	Select when requiring dual-sourcing assurance or alternate logistics channel
IPP60R1K4C7	600 V rating, 1.4 Ω R_DS(on), 9.5 nC Q_g; CoolMOS™ C7 platform with improved E_oss (0.92 µJ @ 400 V)	Requires revised input capacitor and clamp design for 600 V rating-unsuitable for 265 VAC + surge applications	Choose only if system input is limited to ≤230 VAC and higher efficiency at light load is prioritized

Compared with IPD70R1K4CE and IPP60R1K4C7, IPSA70R1K4CEAKMA1 uniquely combines 700 V rating, ISO-standoff isolation, and CE-series cost-performance balance-making it optimal for universal-input, safety-certified lighting and adapter designs where creepage and surge margin are non-negotiable.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

A 10.2 Ω gate resistor is specified in the datasheet for characterization (t_d(on) = 7.7 ns, t_f = 18.2 ns). For production use, values between 4.7 Ω and 15 Ω maintain safe dv/dt control while minimizing switching loss. Values above 22 Ω increase turn-off loss and risk shoot-through in half-bridge configurations.

Does the ISO-standoff drain require special PCB layout considerations?

Yes-the ISO-standoff isolates the drain pad from the leadframe, enabling ≥4 mm creepage without PCB slots. Maintain ≥3.5 mm clearance from adjacent traces and ground planes, and avoid solder mask over the standoff region to preserve insulation integrity per IEC 62368-1 Annex G.

Can this MOSFET replace older CoolMOS™ C3 or C6 parts in existing designs?

Yes, with verification: IPSA70R1K4CEAKMA1 has identical pinout and R_DS(on) to C3/C6 equivalents but lower Q_g and E_oss. Gate drive timing must be rechecked-its faster switching may require reduced gate resistance and updated snubber values to manage increased dv/dt.

Is the body diode suitable for synchronous rectification?

No-the body diode has 200 ns t_rr and 0.9 µC Q_rr, making it unsuitable for synchronous rectification above 50 kHz. It is optimized for freewheeling in DCM flyback, not high-frequency bidirectional conduction. Use external Schottky or MOSFET-based SR controllers instead.
