Product details

Overview

IPA60R1K5CEXKSA1 from Infineon Technologies is a 600 V, 1.5 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in TO-220 FP package, optimized for high-efficiency PFC and hard-switching SMPS stages in consumer lighting and adapter applications. It delivers 9.4 nC gate charge, 1 µJ E_oss at 400 V, and supports 5 A continuous drain current at T_C = 25 °C.

For engineers reviewing the IPA60R1K5CEXKSA1 datasheet, IPA60R1K5CEXKSA1 pinout, IPA60R1K5CEXKSA1 application, or IPA60R1K5CEXKSA1 equivalent, key selection criteria include its low FOM (R_DS(on) × Q_g), high commutation ruggedness, and ease of gate drive in cost-sensitive 600 V switching topologies.

Technical Context

This device implements Infineon's CoolMOS™ CE superjunction architecture with optimized charge balancing for reduced conduction and switching losses. Its 6.4 °C/W junction-to-case thermal resistance and 20 W power dissipation rating enable thermally constrained designs without forced cooling.

The MOSFET features a 2.5–3.5 V gate threshold voltage, 5.4 V gate plateau, and robust 50 V/ns dv/dt ruggedness-ensuring reliable operation in noisy PFC and resonant converter environments where fast voltage transients occur across the drain-source path.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS max	650 V - Withstands surge voltages up to 650 V during transient events in 400 V AC-input PFC stages
R_DS(on) max @ 150 °C	1.50 Ω - Ensures stable on-resistance under full thermal load in enclosed lighting drivers
Q_g typ	9.4 nC - Enables efficient 100–300 kHz switching with standard 12 V gate drivers and minimal gate loss
E_oss @ 400 V	1 µJ - Reduces turn-off energy loss in hard-switched boost PFC circuits operating near 400 V DC bus
I_D cont @ T_C=25°C	5 A - Supports continuous output power up to ~120 W in single-stage flyback adapters
di/dt ruggedness	500 A/µs - Maintains safe reverse recovery behavior during high di/dt commutation in LLC half-bridge outputs
T_j max	150 °C - Allows operation in sealed indoor lighting enclosures without derating below ambient 70 °C

Pinout & Package

IPA60R1K5CEXKSA1 is housed in a TO-220 FullPAK (FP) package with isolated tab. The plastic body provides reinforced insulation (2500 V_rms) and enables direct heatsink mounting without insulating pads.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Accepts 0–20 V logic-level gate drive; 14 Ω internal gate resistance simplifies RC snubber design
Pin 2 (Drain)	High-voltage power terminal	Connected to drain of internal superjunction cell array; electrically tied to metal tab for thermal conduction
Pin 3 (Source)	Power return / reference node	Serves as common source for gate drive loop and current sensing; low-inductance layout critical for EMI control

Key Features

Feature	Design Value
Ultra-low FOM (R_DS(on) × Q_g)	1.5 Ω × 9.4 nC = 14.1 Ω·nC - Delivers best-in-class efficiency trade-off for 600 V consumer-grade SMPS
High commutation ruggedness	26 mJ single-pulse avalanche energy - Survives unclamped inductive switching events in PFC choke failures
Easy gate drive	5.4 V gate plateau voltage - Reduces risk of Miller-induced false turn-on in high-dv/dt half-bridge configurations
Pb-free & halogen-free	RoHS-compliant plating and mold compound - Meets IEC 61249-2-21 and JEDEC J-STD-020 reflow requirements

Equivalent & Alternatives

The following parts are listed as comparable options for similar 600 V superjunction MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP60N6F6	R_DS(on) = 0.95 Ω, Q_g = 12.5 nC, TO-220 package	Higher conduction loss but lower switching loss margin due to higher Q_g; requires stronger gate driver	Prefer when lower R_DS(on) dominates over gate drive simplicity in fixed-frequency PFC
IPP60R1K5C6	R_DS(on) = 1.5 Ω, Q_g = 10.2 nC, same TO-220 FP package	Same R_DS(on), slightly higher Q_g and E_oss; no integrated gate resistor	Choose when legacy board layout compatibility with IPP60R1K5C6 is required and minor efficiency penalty is acceptable

Compared with STP60N6F6 and IPP60R1K5C6, IPA60R1K5CEXKSA1 offers the lowest combined conduction–switching loss (FOM) and built-in gate resistance for simplified drive, making it optimal for cost-driven lighting and adapter designs requiring rapid time-to-market.

FAQ

What is the maximum recommended gate resistor value for IPA60R1K5CEXKSA1 in a 100 kHz PFC application?

A 12.2 Ω external gate resistor is validated in the datasheet for 100–300 kHz operation with 13 V drive. Using ≥15 Ω increases turn-off time beyond 50 ns, risking shoot-through in bridge configurations. For 100 kHz PFC, 10–12 Ω balances switching loss and EMI, matching the 14 Ω internal gate resistance.

Does IPA60R1K5CEXKSA1 require a gate driver with negative turn-off capability?

No. Its 5.4 V gate plateau and 2.5–3.5 V V_GS(th) ensure stable turn-on with 10–12 V positive drive and simple pull-down via 10 kΩ resistor. Negative turn-off is unnecessary unless operating above 300 kHz with aggressive dv/dt (>40 V/ns) in unshielded layouts.

Can IPA60R1K5CEXKSA1 be paralleled for higher current in a 200 W LED driver?

Yes, but gate ferrite beads (600 Ω @ 100 MHz) are mandatory per gate line to suppress oscillation. Layout must mirror trace lengths and use Kelvin source connections. Derate total current by 20% versus sum of individual ratings due to R_DS(on) mismatch across temperature.

Is the TO-220 FP package of IPA60R1K5CEXKSA1 electrically isolated from the drain?

Yes. The TO-220 FullPAK variant features reinforced insulation between the metal tab (drain-connected) and mounting surface, rated for 2500 V_rms isolation. This eliminates need for insulating pads in heatsink mounting, reducing thermal resistance by ~0.5 °C/W versus standard TO-220.
