Product details

Overview

IPA65R1K0CEXKSA1 from Infineon Technologies is a 650 V, 1.0 Ω R_DS(on) superjunction MOSFET in TO-220 FP package, optimized for high-efficiency, cost-sensitive offline SMPS in lighting and adapter applications. It delivers 7.2 A continuous drain current at T_C = 25°C, features 15.3 nC total gate charge, and supports 400 V E_oss of 1.5 µJ.

For engineers reviewing the IPA65R1K0CEXKSA1 datasheet, IPA65R1K0CEXKSA1 pinout, IPA65R1K0CEXKSA1 application, or IPA65R1K0CEXKSA1 equivalent, key selection criteria include its CoolMOS™ CE platform's low FOM (R_DS(on) × Q_g), high commutation ruggedness, and ease of gate drive in discontinuous conduction mode (DCM) flyback topologies.

Technical Context

This device implements Infineon's CoolMOS™ CE superjunction architecture with optimized charge balancing for reduced conduction and switching losses. Its 650 V V_(BR)DSS rating and 700 V absolute maximum V_DS support universal-input AC/DC designs up to 230 V_AC with margin.

The MOSFET integrates an intrinsic fast-recovery body diode (t_rr = 226 ns, Q_rr = 1.3 µC) and exhibits 50 V/ns dv/dt ruggedness, enabling robust operation in hard-switched converters without external snubbers under typical layout conditions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP65N6F6	650 V, 0.6 Ω R_DS(on), 42 nC Q_g, TO-220 package	Higher conduction loss at light load due to lower speed; requires larger gate driver	Prefer when lowest R_DS(on) dominates over switching loss and cost is secondary
IPP65R1K0CFD7	650 V, 1.0 Ω R_DS(on), 17.5 nC Q_g, integrated fast-body diode (t_rr = 130 ns)	Better diode performance but higher Q_g; slightly larger footprint	Prefer when faster diode recovery is critical and layout allows extra gate drive margin

Compared with STP65N6F6 and IPP65R1K0CFD7, IPA65R1K0CEXKSA1 offers the best balance of low Q_g, proven commutation ruggedness, and cost-making it optimal for high-volume, thermally constrained lighting and adapter designs where gate drive simplicity and EMI control are prioritized.

FAQ

What is the maximum recommended gate resistor value for stable switching?

The datasheet specifies R_G = 10.2 Ω for all dynamic timing measurements (e.g., t_d(on), t_r). Using >15 Ω increases switching time and E_on/E_off, while <5 Ω risks gate oscillation. For 65–100 kHz DCM flyback, 10 Ω ±10% is optimal for EMI and loss trade-off.

Can IPA65R1K0CEXKSA1 be paralleled for higher current capability?

Yes, but only with matched units and individual ferrite beads (≥100 Ω @ 100 MHz) on each gate lead, as explicitly recommended in the datasheet. Without gate isolation, current imbalance exceeds 25% due to parameter spread and layout asymmetry, risking thermal runaway.

Is the TO-220FP package electrically insulated?

Yes-the TO-220FP FullPAK variant has reinforced insulation between drain (tab) and leads, rated for 2500 V_RMS for 1 minute. This eliminates need for insulating pads in heatsink mounting, reducing thermal resistance by ~0.5 °C/W versus standard TO-220.

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

No-the datasheet specifies V_GS = –30 V maximum for dynamic conditions, but no negative bias is required. Standard 0 V to +13 V gate drive suffices; negative voltage adds complexity without benefit for this device's V_GS(th) and dV/dt immunity.
