Product details

Overview

IPS70R950CEAKMA1 from Infineon Technologies is a 700 V, 950 mΩ superjunction MOSFET in PG-TO251 (IPAK) package, optimized for high-efficiency, cost-sensitive offline SMPS in lighting and adapter applications. It delivers 7.4 A continuous drain current at T_C = 25°C, features 15.3 nC total gate charge, and integrates an integrated fast-recovery body diode with 226 ns reverse recovery time.

For engineers reviewing the IPS70R950CEAKMA1 datasheet, IPS70R950CEAKMA1 pinout, IPS70R950CEAKMA1 application, or IPS70R950CEAKMA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, E_oss at 400 V (1.5 µJ), commutation ruggedness (50 V/ns dv/dt), and thermal resistance (R_thJC = 1.85 °C/W).

Technical Context

This CoolMOS™ CE device employs superjunction architecture to achieve low R_DS(on) × Q_g figure-of-merit and reduced switching losses while maintaining robust hard-switching capability. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V) support standard 10–13 V gate drive without requiring negative turn-off bias.

The integrated body diode exhibits controlled reverse recovery (Q_rr = 1.3 µC, I_rrm = 9.9 A) and high commutation ruggedness (dv/dt = 50 V/ns, dif/dt = 500 A/µs), enabling reliable operation in flyback and resonant topologies without external snubbers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	700 V - Rated blocking voltage for universal AC input (85–265 VAC) offline converters
R_DS(on),max	950 mΩ @ T_j = 150°C - Enables thermally stable conduction loss in compact heatsink designs
Q_g,typ	15.3 nC - Low gate drive power requirement compatible with standard PWM controllers
E_oss@400V	1.5 µJ - Reduces turn-on switching loss in high-frequency flyback and PFC stages
I_D,typ	7.4 A @ T_C = 25°C - Supports up to ~65 W output power in adapter designs with adequate PCB copper
R_thJC	1.85 °C/W - Enables direct mounting to heatsink for thermal management in enclosed lighting fixtures
trr	226 ns - Limits diode-induced switching loss and EMI in discontinuous conduction mode (DCM) operation

Pinout & Package

IPS70R950CEAKMA1 is housed in PG-TO251 (IPAK) package with exposed drain tab for thermal enhancement. The package uses standard through-hole mounting and supports wave soldering at leads (260°C, 10 s, 1.6 mm from case).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; requires <10.2 Ω series gate resistor for stable 13 V switching (td(on) = 6.6 ns)
Pin 2 / Tab	Drain	Main high-side power terminal; electrically connected to exposed metal tab for heatsinking
Pin 3	Source	Power return path and gate reference; connects to PCB ground plane for low-inductance layout

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPD70R950CE	Same die, PG-TO252 (DPAK) package; R_thJC = 2.1 °C/W; 3-pin SMD footprint	Better suited for reflow-soldered, space-constrained PCBs where manual assembly is avoided	Select when automated assembly and lower profile (<2.3 mm) are prioritized over thermal performance
IPP60R950CE	600 V rating, identical R_DS(on)/Q_g; higher ID,pulse (14 A); same IPAK package	Restricted to 230 VAC-only or DC-fed systems; not suitable for universal-input designs	Choose only for fixed-line applications where 700 V margin is unnecessary and cost reduction is critical

Compared with IPD70R950CE and IPP60R950CE, IPS70R950CEAKMA1 offers superior thermal resistance (1.85 vs. 2.1 °C/W) and universal AC input compatibility (700 V vs. 600 V), making it optimal for cost-sensitive, thermally constrained offline SMPS where reliability across global mains voltages is required.

FAQ

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

A 10.2 Ω gate resistor is specified in the datasheet for test conditions (V_GS = 13 V, I_D = 2.2 A). For production designs, values between 5 Ω and 15 Ω balance switching speed, overshoot suppression, and EMI control. Higher values (>22 Ω) increase turn-on delay beyond 10 ns and risk shoot-through in half-bridge configurations.

Does IPS70R950CEAKMA1 require a negative gate voltage for reliable turn-off?

No. The device's gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V) allow full turn-off with 0 V gate drive. Negative bias is unnecessary and not recommended, as V_GS ratings limit dynamic swing to ±30 V-exceeding 0 V turn-off adds complexity without improving commutation behavior or diode recovery.

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

Yes, with verification. IPS70R950CEAKMA1 shares identical pinout and R_DS(on) spec with C3/C6 equivalents but improves E_oss by 30% and reduces Q_g by ~12%. Layout changes are typically unnecessary, though gate drive strength and snubber tuning may require minor adjustment due to faster switching edges.

Is the drain tab electrically isolated from the PCB mounting surface?

No. The drain tab is internally connected to Pin 2 and must be electrically isolated from the PCB ground plane using insulating thermal pads or mica washers. Direct mounting to a grounded heatsink is permitted only if the heatsink is isolated from system ground or referenced to high-side potential.
