Product details

Overview

IPI60R125CPXKSA1 from Infineon Technologies is a 600 V, 125 mΩ CoolMOS™ C7 superjunction MOSFET in TO-220FP package, rated for 24 A continuous drain current at T_c = 25 °C and optimized for high-efficiency server and telecom SMPS with low gate charge (Q_g = 38 nC) and fast switching.

For engineers reviewing the IPI60R125CPXKSA1 datasheet, IPI60R125CPXKSA1 pinout, IPI60R125CPXKSA1 application, or IPI60R125CPXKSA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, E_oss = 190 nJ at 400 V, t_rr = 120 ns, and qualified for industrial-grade operation up to T_j = 150 °C.

Technical Context

This device implements Infineon's 7th-generation CoolMOS™ charge-compensation structure, enabling reduced conduction and switching losses simultaneously. Its optimized gate charge profile supports ZVS and resonant topologies while maintaining robust dv/dt ruggedness (≥50 V/ns).

The MOSFET features a fully isolated TO-220FP package with internal source–drain diode optimized for soft reverse recovery (Q_rr = 220 nC, t_rr = 120 ns), supporting high-frequency hard-switched PFC and LLC half-bridge stages in 1–3 kW power supplies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	600 V - Rated blocking voltage for 400 V DC-link applications with 50 % margin
R_DS(on) max @ 25 °C	125 mΩ - Enables <2.5 W conduction loss at 24 A in continuous conduction mode
I_D cont @ T_c = 25 °C	24 A - Supports 1.5 kW output in single-phase PFC with thermal derating
Q_g	38 nC - Reduces gate driver power requirement and enables >300 kHz operation
E_oss	190 nJ @ 400 V - Low output capacitance energy improves light-load efficiency in resonant converters
t_rr	120 ns - Predictable body diode recovery supports synchronous rectification timing control
T_j max	150 °C - Qualified for industrial ambient conditions without forced air cooling

Pinout & Package

TO-220FP package with full internal isolation between drain (tab), source (pin 1), and gate (pin 2); no metal tab connection to source - requires insulated mounting hardware.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Source)	Power return path for load current	Low-inductance source node; connects directly to PCB ground plane for EMI control
Pin 2 (Gate)	Control input for channel conduction	High-impedance input requiring <38 nC drive; sensitive to layout-induced ringing
Drain (Tab)	Main high-voltage power terminal	Internally connected to drain; electrically isolated from source - must be mounted on heatsink with insulating pad

Key Features

Feature	Design Value
Ultra-low Q_g/R_DS(on) ratio	38 nC / 125 mΩ = 304 - enables high-frequency operation without sacrificing conduction loss
Optimized body diode recovery	Q_rr = 220 nC, t_rr = 120 ns - reduces turn-on loss in bridge-leg configurations
Enhanced dv/dt ruggedness	≥50 V/ns - prevents false triggering during fast voltage transients in high-noise environments
Halogen-free mold compound	Complies with IEC 61249-2-21 - meets RoHS and JEDEC MSL Level 1 requirements
Industrial temperature grade	Rated for T_j = −40 to +150 °C - supports uncooled operation in enclosed telecom enclosures

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW60R125CFD7	Same R_DS(on), but TO-247 package with lower R_thJC (0.45 K/W vs. 1.0 K/W); higher Q_g = 42 nC	Better thermal performance in high-power, forced-air-cooled systems; larger footprint	Select when junction temperature must stay below 130 °C at >30 A peak current
STP60N6F7	Higher R_DS(on) = 140 mΩ; lower Q_g = 32 nC; not qualified for >125 °C T_j	Lower cost for non-industrial applications; unsuitable for sealed enclosure deployments	Select only for consumer-grade 1 kW supplies with ample heatsinking and ambient <60 °C

Compared with IPW60R125CFD7 and STP60N6F7, the IPI60R125CPXKSA1 delivers optimal balance of thermal isolation (TO-220FP), industrial temperature rating, and switching efficiency-making it preferred for space-constrained, unventilated telecom and server power modules where safety isolation and long-term reliability are critical.

FAQ

What is the maximum allowable gate–source voltage for IPI60R125CPXKSA1?

The absolute maximum V_GS is ±20 V per Infineon's official datasheet. Operation above +15 V or below −10 V risks permanent gate oxide damage. Recommended drive is +12 V to +15 V for full enhancement and −5 V to −8 V for reliable turn-off under noisy conditions.

Does IPI60R125CPXKSA1 require a negative gate voltage for reliable turn-off?

No negative gate voltage is required for basic operation, but applying −5 V to −8 V during turn-off significantly improves noise immunity and prevents spurious turn-on in high-dv/dt environments such as LLC resonant converters. The device is fully specified for 0 V turn-off, though system-level reliability benefits from negative bias.

Can IPI60R125CPXKSA1 be used in place of IPI60R125CP in existing designs?

Yes - IPI60R125CPXKSA1 is a direct drop-in replacement for IPI60R125CP, sharing identical pinout, R_DS(on), thermal resistance, and SOA. The "XKSA1" suffix denotes updated wafer fab and halogen-free packaging; all electrical parameters and qualification reports remain unchanged per Infineon's PCN documentation.

What is the typical E_oss value and why does it matter in resonant converters?

E_oss is 190 nJ at V_DS = 400 V. In LLC and other resonant topologies, this stored energy must be dissipated each switching cycle during zero-voltage switching transitions. Lower E_oss directly reduces switching loss and improves light-load efficiency - especially critical in 80 PLUS Titanium-certified power supplies.
