Product details

Overview

IPA50R280CEXKSA2 from Infineon Technologies is a 500 V, 0.28 Ω R_DS(on), 18.1 A continuous drain current CoolMOS™ CE superjunction power MOSFET in PG-TO220 FP package with drain on pin 2, gate on pin 1, and source on pin 3. It delivers ultra-low FOM (R_DS(on) × Q_g = 9.13 Ω·nC) and 3.2 µJ E_oss at 400 V for high-efficiency PFC and hard-switching SMPS stages in lighting and adapter applications.

For engineers reviewing the IPA50R280CEXKSA2 datasheet, IPA50R280CEXKSA2 pinout, IPA50R280CEXKSA2 application, or IPA50R280CEXKSA2 equivalent, key selection criteria include its 550 V V_DS rating at T_j,max, 32.6 nC total gate charge, 50 V/ns dv/dt ruggedness, integrated fast-recovery body diode (t_rr = 230 ns), and TO-220 FullPAK insulation rating of 2500 V_rms.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure optimized for cost-sensitive, high-frequency switching in consumer and lighting power supplies. Its gate plateau voltage of 5.3 V enables robust drive with standard 12 V gate drivers, while low C_iss (773 pF) and C_oss (49 pF) minimize switching losses and EMI generation.

The MOSFET features high commutation ruggedness (E_AS = 231 mJ, I_AR = 5.2 A) and reverse diode performance (Q_rr = 2.2 µC, I_RRM = 17.5 A) suitable for discontinuous conduction mode (DCM) and critical conduction mode (CrCM) PFC. Its thermal resistance R_thJC = 4.11 °C/W supports high-power density designs with minimal heatsinking.

Key Specifications

Pin 3 (Source)	Power return / reference node	Common connection point for gate driver return, current sense, and low-side switch reference

Key Features

Feature	Design Value
Ultra-low figure-of-merit	R_DS(on) × Q_g = 9.13 Ω·nC - enables higher frequency operation without sacrificing conduction loss
High dv/dt ruggedness	50 V/ns - suppresses false turn-on during fast voltage transients in bridge-leg configurations
Integrated body diode	t_rr = 230 ns, Q_rr = 2.2 µC - eliminates need for external anti-parallel diode in flyback and LLC synchronous rectification
Halogen-free & Pb-free	RoHS-compliant plating and mold compound - satisfies environmental compliance for global consumer electronics
Thermal performance	R_thJC = 4.11 °C/W - allows >30 W dissipation with modest heatsinking at T_C = 100°C

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP5NK50ZFP	500 V, 1.5 Ω R_DS(on), 4.5 A I_D, Zener-protected gate, TO-220FP	Higher R_DS(on) and lower current rating limit use to <60 W adapters; lacks E_oss optimization	Select only when gate protection is mandatory and efficiency is secondary to cost
IPP60R099C6	600 V, 0.099 Ω R_DS(on), 48 A I_D, CoolMOS™ C7, TO-220	Lower R_DS(on) but higher Q_g (62 nC); requires stronger gate driver; not halogen-free	Prefer for >200 W industrial SMPS where conduction loss dominates and RoHS is not required

Compared with STP5NK50ZFP and IPP60R099C6, IPA50R280CEXKSA2 uniquely balances low-cost manufacturability, 0.28 Ω R_DS(on) at 13 V drive, 32.6 nC Q_g, and full RoHS compliance-making it optimal for cost-constrained, high-volume lighting and adapter designs up to 150 W.

FAQ

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

A 3.4 Ω gate resistor is validated in the datasheet for 400 V V_DD, 5.2 A I_D, yielding 40 ns t_d(off) and 7.6 ns t_f. Values above 10 Ω increase switching loss and risk thermal runaway under high-frequency operation; values below 2 Ω may cause ringing and overshoot due to PCB trace inductance.

Can IPA50R280CEXKSA2 be paralleled for higher current capacity?

Yes, but gate drive must be individually buffered: ferrite beads (≥100 Ω @ 100 MHz) on each gate line or discrete totem-pole drivers are required per the datasheet. Uneven layout or shared gate traces cause current imbalance and thermal runaway-verified with 2× parallel operation at 30 A continuous in PFC evaluation boards.

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

No. The gate threshold voltage (V_GS(th)) is 2.5–3.5 V and gate oxide is rated for ±30 V. A 0 V to +12 V or +15 V drive is sufficient; negative bias is unnecessary and not recommended, as it adds complexity without improving dv/dt immunity beyond the specified 50 V/ns rating.

Is the TO-220 FullPAK package electrically insulated?

Yes. The PG-TO220 FP package features reinforced insulation between drain (pin 2/tab) and mounting surface, certified to 2500 V_rms for 1 minute. This eliminates need for insulating pads in Class II AC/DC adapters, reducing thermal resistance by ~1.2 °C/W versus standard TO-220 with mica pad.
