Product details

Overview

IPU95R2K0P7AKMA1 from Infineon is a 950V superjunction N-channel MOSFET in PG-TO251-3 (IPAK) package, featuring R_DS(on) max 2 Ω at V_GS = 10 V, Q_g typ 10 nC, V_GS(th) typ 3 V with ±0.5 V variation, integrated ESD protection (HBM Class 2), and internal body diode. It is optimized for flyback converters in LED lighting, low-power adapters, smart meters, and auxiliary power supplies.

For engineers reviewing the IPU95R2K0P7AKMA1 datasheet, IPU95R2K0P7AKMA1 pinout, IPU95R2K0P7AKMA1 application, or IPU95R2K0P7AKMA1 equivalent, key selection criteria include 950V V_DS rating, low gate charge for high-frequency switching, tight threshold voltage distribution for parallel operation, and robust avalanche capability (E_AS = 6 mJ).

Technical Context

This CoolMOS™ P7 device employs charge-compensation superjunction architecture to achieve best-in-class figure-of-merit R_DS(on) × E_oss, with C_iss = 330 pF and C_oss = 5 pF at V_DS = 400 V. Its 3 V gate threshold enables direct drive from standard 3.3 V/5 V controllers without level-shifting.

The integrated Zener-protected gate structure provides HBM Class 2 ESD immunity, while the internal body diode exhibits t_rr = 337 ns and Q_rr = 2 µC under 50 A/µs commutation-critical for minimizing switching losses in discontinuous conduction mode (DCM) flyback topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - supports primary-side switching in universal-input offline flyback designs up to 400 VAC mains with margin.
R_DS(on), max	2 Ω @ V_GS = 10 V, T_j = 25°C - enables low conduction loss in <4 A continuous drain current applications.
Q_g, typ	10 nC - reduces gate drive power and allows use of smaller gate drivers in high-frequency (>100 kHz) SMPS.
V_GS(th), typ	3 V with ±0.5 V variation - ensures consistent turn-on across temperature and batch, supporting reliable paralleling.
E_oss @ 500 V	0.9 µJ - lowers turn-off energy loss, improving efficiency in hard-switched flyback and PFC stages.
t_rr	337 ns - limits reverse recovery overshoot and EMI in diode-commutated transitions.
R_thJC	3.4 °C/W - enables thermal design with ≤37 W power dissipation at T_C = 25°C using standard PCB copper area.

Pinout & Package

IPU95R2K0P7AKMA1 uses the PG-TO251-3 (IPAK) surface-mount package with gull-wing leads. The package features isolated drain pad for enhanced thermal performance and creepage distance suitable for reinforced insulation in AC/DC converters.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Gate	Control terminal; accepts 0–20 V DC or pulsed drive; low input capacitance (C_iss = 330 pF) eases driver selection.
Pin 2	Drain	High-voltage power terminal; connected to transformer primary and bulk capacitor; electrically isolated from case.
Pin 3	Source	Power return and reference node; ties to PWM controller ground; carries full load current and diode reverse recovery current.

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss FOM	Enables >90% efficiency in 15–65 W flyback designs operating at 65–130 kHz without active cooling.
V_GS(th) = 3 V ±0.5 V	Reduces risk of partial turn-on during startup or noise coupling, improving system reliability in noisy industrial environments.
Integrated Zener ESD protection (HBM Class 2)	Eliminates need for external gate protection components, lowering BOM count and assembly cost in high-volume adapter production.
950 V breakdown voltage	Supports 230 VAC + 15% surge (265 VAC) with ≥2× safety margin, meeting IEC 62368-1 reinforced insulation requirements.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP9NK90ZFP	900 V V_DS, R_DS(on) = 2.2 Ω, Q_g = 15 nC, no integrated ESD diode	Limited to 230 VAC-only designs; requires external gate protection	Select when cost sensitivity outweighs ESD robustness and 950 V margin is not required.
IPP65R1K0CFD7	650 V V_DS, R_DS(on) = 1.0 Ω, Q_g = 12.5 nC, CoolMOS™ CFD7 with fast body diode	Not suitable for universal-input flyback; only valid for 115 VAC or PFC+LLC architectures	Choose only for 115 VAC-only applications where lower R_DS(on) justifies reduced voltage rating.

Compared with STP9NK90ZFP and IPP65R1K0CFD7, IPU95R2K0P7AKMA1 delivers superior voltage margin, lower gate charge, and built-in ESD protection-making it the optimal choice for universal-input, high-reliability flyback converters where long-term field stability and design simplicity are critical.

FAQ

What is the maximum continuous drain current for IPU95R2K0P7AKMA1 at 100°C case temperature?

The maximum continuous drain current is 2.4 A at T_C = 100°C, derated from 4 A at T_C = 25°C per the thermal resistance R_thJC = 3.4 °C/W and T_j,max = 150°C limit. This value assumes adequate PCB copper area for heat spreading and no forced airflow.

Does IPU95R2K0P7AKMA1 require an external gate resistor for safe paralleling?

Yes-Infineon recommends individual ferrite beads or separate totem-pole drivers on each gate when paralleling multiple IPU95R2K0P7AKMA1 units. This mitigates oscillation and current imbalance caused by gate loop inductance and parameter mismatch, even with its tight V_GS(th) distribution.

Can this MOSFET be used in continuous conduction mode (CCM) PFC boost stages?

No-while rated for 950 V, its R_DS(on) of 2 Ω and Q_g of 10 nC are optimized for DCM/QR flyback, not high-current CCM PFC. For PFC, Infineon recommends higher-current variants like IPU95R380P7 (380 mΩ) or dedicated PFC controllers with lower R_DS(on).

Is the internal body diode suitable for synchronous rectification?

No-the internal body diode has t_rr = 337 ns and Q_rr = 2 µC, which causes significant switching loss and voltage overshoot if used for synchronous rectification. It is intended only for freewheeling in flyback or clamp circuits-not for active rectification.
