Product details

Overview

IPD70R950CEAUMA1 from Infineon Technologies is a 700 V, 950 mΩ superjunction N-channel MOSFET in PG-TO252 (DPAK) package, optimized for high-efficiency, cost-sensitive offline SMPS in lighting and adapter applications. It delivers 7.4 A continuous drain current at 25°C, 15.3 nC total gate charge, and 1.5 µJ output switching energy at 400 V.

For engineers reviewing the IPD70R950CEAUMA1 datasheet, IPD70R950CEAUMA1 pinout, IPD70R950CEAUMA1 application, or IPD70R950CEAUMA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, E_oss-driven light-load efficiency, commutation ruggedness under hard-switching, and DPAK thermal performance in compact board layouts.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure enabling low R_DS(on) × Q_g figure-of-merit (FOM) of 14.5 Ω·nC and ultra-low E_oss (1.5 µJ @ 400 V), directly reducing conduction and switching losses in 65–100 kHz flyback and PFC stages. Its 50 V/ns dv/dt ruggedness and 500 A/µs diode commutation speed support reliable operation in high-noise, high-dV/dt environments without snubbers.

The MOSFET integrates an optimized body diode with 226 ns reverse recovery time and 1.3 µC Q_rr, minimizing voltage overshoot during synchronous rectification or freewheeling. Gate plateau voltage is fixed at 5.4 V, simplifying driver design and ensuring stable turn-on across temperature and load conditions.

Pinout & Package

IPD70R950CEAUMA1 uses the PG-TO252 (DPAK) package with exposed drain tab for enhanced thermal conduction. The 3-pin configuration supports PCB-level thermal management via soldered tab area.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal requiring ≤20 V static / ≤30 V dynamic voltage; low 5.5 Ω internal gate resistance eases driver selection
Pin 2 + Tab	Drain	Main high-voltage power path; tab must be soldered to copper pour for thermal and electrical continuity
Pin 3	Source	Reference node for gate drive and current sensing; connects to primary ground in flyback/PFC circuits

Key Features

Feature	Design Value
Superjunction architecture	Enables 950 mΩ R_DS(on) at 700 V rating-reducing conduction loss by 22% vs. planar MOSFETs of same die size
Low E_oss (1.5 µJ @ 400 V)	Directly improves light-load efficiency in quasi-resonant and CCM flyback converters
High commutation ruggedness	500 A/µs diode dif/dt and 50 V/ns dv/dt rating eliminate need for external snubbers in most SMPS designs
Pb-free plating & halogen-free mold compound	Meets RoHS 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) requirements

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP7NK70ZFP	700 V, 1.2 Ω R_DS(on), 22 nC Q_g, TO-220FP package	Higher conduction loss and gate drive demand; requires larger heatsink	Preferred where legacy TO-220 footprint compatibility is mandatory and efficiency targets are relaxed
FDPF7N70T	700 V, 1.0 Ω R_DS(on), 17.5 nC Q_g, TO-220F package	Higher R_DS(on) and thermal resistance (2.5 °C/W) limit power density in space-constrained designs	Suitable for lower-cost, non-compact adapters where DPAK mounting is not feasible

Compared with STP7NK70ZFP and FDPF7N70T, IPD70R950CEAUMA1 delivers superior power density due to its DPAK package, lower R_DS(on), and 25% lower E_oss, making it optimal for miniaturized, high-efficiency lighting and adapter designs where thermal and layout constraints are critical.

FAQ

What is the maximum junction temperature rating for IPD70R950CEAUMA1?

The absolute maximum operating junction temperature is 150°C, validated per JEDEC JESD22-A108. Thermal design must ensure steady-state T_j remains below this limit under worst-case ambient and power dissipation conditions, using the specified R_thJC = 1.85 °C/W and board-level thermal resistance.

Does IPD70R950CEAUMA1 require a gate resistor for EMI suppression?

A gate resistor is recommended-typically 10–22 Ω-to dampen ringing caused by parasitic inductance in the gate loop. The device's 5.5 Ω internal gate resistance and low Q_gd/Q_gs ratio inherently reduce Miller effect, but external tuning ensures clean switching edges and meets CISPR-22 Class B conducted EMI limits.

Can IPD70R950CEAUMA1 replace older CoolMOS™ C3 or C6 devices in existing designs?

Yes-pin-compatible with same DPAK footprint and identical gate threshold (2.5–3.5 V), but requires validation of gate drive strength due to 15.3 nC Q_g being ~12% higher than C3 equivalents. Layout and snubber values may remain unchanged thanks to improved dv/dt and commutation ruggedness.

Is the body diode suitable for synchronous rectification in LLC resonant converters?

No-the integrated body diode has 226 ns t_rr and 9.9 A I_rrm, which is insufficient for high-frequency synchronous rectification. It is rated for freewheeling and clamping only; external Schottky or GaN FETs are required for true synchronous operation above 100 kHz.
