Product details

Overview

IPU95R1K2P7AKMA1 from Infineon is a 950 V, 1.2 Ω R_DS(on) superjunction MOSFET in PG-TO251-3 (IPAK) package, featuring 3 V gate threshold, integrated Zener ESD protection, and optimized for flyback and PFC topologies in LED lighting, smart meters, and auxiliary power supplies.

For engineers reviewing the IPU95R1K2P7AKMA1 datasheet, IPU95R1K2P7AKMA1 pinout, IPU95R1K2P7AKMA1 application, or IPU95R1K2P7AKMA1 equivalent, key selection criteria include its 950 V V_DS, low 15 nC Q_g, 1.3 µJ E_oss at 500 V, ±0.5 V V_GS(th) tolerance, and industrial-grade JEDEC qualification.

Technical Context

This CoolMOS™ P7 device uses charge compensation technology to achieve best-in-class R_DS(on) × E_oss figure of merit, with 478 pF C_iss, 7 pF C_oss, and 12 pF Co(er) enabling high-frequency switching up to 100 V/ns dv/dt ruggedness.

It integrates an internal body diode with 0.9 V V_SD and 560 ns trr, and features a 3 V V_GS(th) with minimal ±0.5 V variation-enabling reliable gate drive with standard 5 V controllers and simplifying parallel operation without external gate resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - supports primary-side switching in universal-input offline flyback and PFC stages up to 400 V DC bus with margin.
R_DS(on), max	1.2 Ω @ T_j = 150 °C - enables 6 A continuous drain current with <52 W power dissipation at T_C = 25 °C.
Q_g, typ	15 nC - reduces gate drive loss and allows use of low-power gate drivers like 6 A peak ICs without buffering.
E_oss @ 500 V	1.3 µJ - lowers turn-off energy loss in hard-switched applications, improving efficiency in 65–100 kHz flyback designs.
V_GS(th), typ	3 V with ±0.5 V variation - ensures consistent turn-on across temperature and lot, reducing risk of shoot-through in half-bridge configurations.
ESD Class (HBM)	Class 2 - integrated Zener diode provides on-chip protection against human-body-model discharges up to 2 kV.
T_j Range	−55 °C to +150 °C - qualified per JEDEC for industrial ambient conditions and sustained thermal cycling.

Pinout & Package

IPU95R1K2P7AKMA1 is housed in PG-TO251-3 (IPAK), a surface-mount variant of TO-251 with isolated leadframe and thermally enhanced drain pad. The package supports >2.4 °C/W junction-to-case thermal resistance and is compatible with standard reflow profiles (peak 260 °C).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Source terminal	Reference node for gate drive; connects to power ground or low-side return path; carries full load current in low-side switch configuration.
Pin 2 (Gate)	Control input	High-impedance MOSFET gate requiring <15 nC charge; 1 Ω internal R_G aids stability during switching transitions.
Pin 3 (Drain)	Power output	High-voltage drain node connected to transformer primary or PFC inductor; includes integrated body diode (anode to source, cathode to drain).

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss	Enables higher switching frequencies without sacrificing conduction or switching loss balance in compact flyback adapters.
3 V V_GS(th) with ±0.5 V variation	Reduces gate driver voltage headroom requirement and improves production yield in high-volume consumer power supply manufacturing.
Integrated Zener ESD protection	Eliminates need for external TVS on gate line, lowering BOM count and PCB area in space-constrained smart meter designs.
100 V/ns dv/dt ruggedness	Prevents false turn-on during fast voltage transients in high-noise industrial environments without snubber networks.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPU95R1K2P7ATMA1	Same die, tape-and-reel packaging (vs. tube); identical electrical specs and thermal performance.	No functional difference; selected for automated SMT assembly lines requiring reel feed.	Choose for high-volume pick-and-place production where tube handling is impractical.
IPU95R1K2P7XKMA1	Same die, extended temperature grade (−55 °C to +175 °C junction), same R_DS(on) and Q_g.	Required for automotive under-hood or high-ambient industrial PFC where T_j exceeds 150 °C.	Choose only when ambient or thermal design requires >150 °C junction capability; otherwise, standard grade suffices.

Compared with IPU95R1K2P7AKMA1, the ATMA1 variant offers identical performance in automated assembly contexts, while the XKMA1 extends junction temperature range for extreme thermal environments-neither changes circuit design but affects procurement and reliability envelope.

FAQ

Is IPU95R1K2P7AKMA1 suitable for paralleling in high-current PFC designs?

Yes-its tight ±0.5 V V_GS(th) tolerance and low 1.2 Ω R_DS(on) variation support stable current sharing. Infineon recommends using ferrite beads on individual gate lines or discrete totem-pole drivers to suppress oscillation during simultaneous switching.

What is the maximum recommended gate resistor value for 65 kHz flyback operation?

For stable 65 kHz switching with minimal overshoot, a 10 Ω series gate resistor is typical. This balances turn-on speed (reducing conduction loss) and dV/dt control (preventing EMI and false triggering), given the device's 15 nC Q_g and 1 Ω internal R_G.

Does the integrated body diode support continuous conduction mode (CCM) in PFC?

No-the body diode is optimized for flyback freewheeling and clamping, not sustained CCM reverse recovery. For PFC boost stages, external ultrafast diodes or synchronous rectification are recommended to avoid excessive Q_rr-related losses.

Can this MOSFET replace older CoolMOS™ C3 or C7 devices in existing designs?

Yes-pin-compatible with PG-TO251-3 footprint and improved R_DS(on), Q_g, and E_oss. However, verify gate drive strength (due to lower V_GS(th)) and adjust snubber values if dv/dt exceeds legacy design margins.
