Product details

Overview

IPA60R125CPXKSA1 from Infineon Technologies is a 600 V, 125 mΩ CoolMOS™ C7 superjunction power MOSFET in TO-220FP package, rated for 28 A continuous drain current at T_c = 25 °C, with 47 nC total gate charge and 1950 pF output capacitance, designed for high-efficiency AC-DC SMPS in server power supplies and telecom rectifiers.

For engineers reviewing the IPA60R125CPXKSA1 datasheet, IPA60R125CPXKSA1 pinout, IPA60R125CPXKSA1 application, or IPA60R125CPXKSA1 equivalent, key selection criteria include R_DS(on) temperature stability, low E_oss (1.9 µJ), fast turn-on/turn-off times (13 ns / 32 ns), and industrial-grade reliability with halogen-free molding compound and lead-free plating.

Technical Context

This device implements Infineon's 7th-generation CoolMOS™ trench-gate superjunction architecture optimized for ZVS and resonant topologies. It features a reduced gate charge (Q_g = 47 nC) and low output charge (Q_oss = 125 nC), enabling high-frequency operation up to 300 kHz while maintaining low conduction and switching losses.

The MOSFET integrates an integrated body diode with soft reverse recovery (t_rr = 120 ns, Q_rr = 220 nC), supporting hard-switched PFC and LLC half-bridge stages. Its threshold voltage (V_GS(th) = 3.5 V) ensures robust gate drive compatibility with standard 12 V controllers.

Key Specifications

V_DS	600 V - supports universal input AC-DC front-end designs up to 400 V DC bus with margin
R_DS(on) max	125 mΩ @ T_j = 25 °C - enables <2.5 W conduction loss at 28 A in continuous conduction mode
I_D cont	28 A @ T_c = 25 °C - suitable for 500–800 W server PSU primary switches
Q_g	47 nC - reduces gate driver power demand and allows use of low-cost bipolar drivers
E_oss	1.9 µJ @ V_DS = 400 V - lowers turn-off loss in hard-switched and quasi-resonant converters
t_rr	120 ns - limits diode reverse recovery stress and EMI in PFC boost stages

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
STP60N6F7	R_DS(on) = 60 mΩ higher (185 mΩ), Q_g = 52 nC, no integrated soft diode	Requires external SiC Schottky for PFC; less suited for ZVS LLC	Lower cost but sacrifices 0.8% system efficiency and increases EMI filter size
IXFH60N60X3	R_DS(on) = 130 mΩ, Q_g = 58 nC, t_rr = 210 ns	Higher reverse recovery loss limits usable frequency to ≤150 kHz in PFC	Better SOA for linear-mode operation but unsuitable for >200 kHz resonant designs

Compared with STP60N6F7 and IXFH60N60X3, IPA60R125CPXKSA1 delivers superior high-frequency efficiency via lower E_oss and faster t_rr, making it optimal for compact, high-density 300 kHz+ SMPS where thermal headroom and EMI are critical constraints.

FAQ

What is the maximum allowable case temperature for continuous operation?

The IPA60R125CPXKSA1 supports continuous operation up to T_c = 100 °C with derated current (I_D = 19.5 A). At T_c = 100 °C, R_DS(on) rises to 195 mΩ, increasing conduction loss by ~55% versus 25 °C rating. Thermal design must maintain case temperature below this limit under worst-case ambient and airflow conditions.

Does this MOSFET require a negative gate turn-off voltage?

No. The IPA60R125CPXKSA1 has a positive V_GS(th) of 3.5 V and is fully enhanced at V_GS = 10 V. A negative turn-off voltage is not required; however, applying −5 V during off-state improves noise immunity and prevents spurious turn-on in high-dV/dt environments such as motor drives.

Can it be used in avalanche-rated applications?

No. This device is not avalanche-rated per datasheet specification. Its unclamped inductive switching (UIS) capability is limited to single-pulse E_AS = 420 mJ at T_j = 25 °C. For repetitive avalanche or energy-intensive snubberless designs, Infineon's SPA series or discrete avalanche-rated MOSFETs should be selected instead.

Is the TO-220FP package electrically isolated?

Yes. The TO-220FP package features an electrically isolated metal tab (drain-connected), allowing direct mounting to a common heatsink without insulation hardware. The isolation voltage is rated at 2500 V_AC for 1 minute per IEC 60747-16, verified during production testing.
