Product details

Overview

IPA50R280CE from Infineon Technologies is a 500 V, 0.28 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO220 FP package, optimized for high-efficiency PFC and hard-switching SMPS stages in consumer and lighting applications. It delivers 18.1 A continuous drain current at T_C = 25°C, 32.6 nC total gate charge, and 3.2 µJ output energy at 400 V.

For engineers reviewing the IPA50R280CE datasheet, IPA50R280CE pinout, IPA50R280CE application, or IPA50R280CE equivalent, key selection criteria include its low R_DS(on) × Q_g figure-of-merit (280 mΩ·nC), high commutation ruggedness (500 A/µs di/dt), and TO-220 FullPAK insulation rating of 2500 V_rms.

Technical Context

This CoolMOS™ CE device implements a superjunction cell structure enabling reduced conduction and switching losses versus planar MOSFETs. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.3 V) support standard 12 V gate drivers without level-shifting.

Designed for unidirectional high-voltage switching, it integrates an intrinsic fast-recovery body diode (t_rr = 230 ns, Q_rr = 2.2 µC) with 15 V/ns reverse dv/dt ruggedness. Thermal resistance R_thJC is 4.11 °C/W, enabling 30.4 W power dissipation at T_C = 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	500 V - Maximum blocking voltage for primary-side switching in 400 V DC-link PFC and SMPS topologies
R_DS(on),max	0.28 Ω @ T_j = 25°C - Enables <1.5 W conduction loss at 4.2 A, critical for thermal management in compact adapters
Q_g,typ	32.6 nC @ V_DD = 400 V - Determines gate driver current requirement (~1.6 A peak for 20 ns rise time)
E_oss	3.2 µJ @ 400 V - Directly impacts turn-off loss in hard-switched converters; 30% lower than prior CoolMOS™ C7
I_D,cont	18.1 A @ T_C = 25°C - Supports >150 W continuous output in single-transistor flyback or PFC boost designs
t_rr	230 ns - Limits diode recovery-related voltage overshoot and EMI in totem-pole PFC and resonant LLC stages

Pinout & Package

Pin 2 (Drain)	High-voltage switch node	Connected to AC rectifier output or transformer primary; electrically isolated from heatsink by molded compound
Pin 3 (Source)	Power return / reference	Serves as local ground for gate driver; must be routed with low inductance to minimize V_GS noise during switching

Key Features

Feature	Design Value

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
IPW60R099P7	650 V rating, 0.099 Ω R_DS(on), higher Q_g (65 nC), TO-247 package	Targets higher-input industrial PFC where 650 V margin is required; unsuitable for cost-sensitive consumer adapters	Choose when V_IN exceeds 305 VAC RMS or surge immunity >6 kV is mandated
STP55N6F6	600 V, 0.06 Ω R_DS(on), no integrated diode optimization, TO-220 non-insulated	Lacks 2500 V isolation and low-Q_rr diode; requires external insulator and snubber in safety-critical designs	Select only for non-isolated DC-DC or low-cost industrial controls where creepage/clearance is not constrained

Compared with IPW60R099P7 and STP55N6F6, IPA50R280CE provides optimal balance of 500 V rating, 0.28 Ω on-resistance, 32.6 nC gate charge, and fully insulated TO-220 FP packaging-making it uniquely suited for space-constrained, safety-certified consumer power supplies requiring both efficiency and regulatory compliance.

FAQ

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

The datasheet specifies RG = 3.4 Ω for dynamic characterization. For stable operation, a 5–10 Ω non-inductive SMD resistor is recommended to dampen gate oscillation while maintaining ≤10 ns rise/fall times. Values above 15 Ω increase switching losses and risk shoot-through in half-bridge configurations.

Can IPA50R280CE be paralleled for higher current capacity?

Yes, but with strict layout constraints: identical gate trace lengths, individual 10 Ω ferrite beads per gate, and Kelvin-source routing to equalize dynamic current sharing. Parallel operation requires matching R_DS(on) within ±5% and thermal coupling via shared heatsink to prevent thermal runaway.

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

No. The gate threshold voltage (2.5–3.5 V) and plateau voltage (5.3 V) are compatible with standard 0 V to 12 V gate drive. A negative turn-off voltage is unnecessary and may accelerate gate oxide degradation; 0 V gate return is sufficient for clean turn-off under all operating conditions.

What is the safe operating area (SOA) limitation at 100°C case temperature?

At T_C = 100°C, the SOA curve limits continuous operation to ≤8 A at 400 V, or ≤12 A at 200 V. Pulse operation up to 42.9 A is permitted for ≤100 µs with duty cycle <1%, provided junction temperature remains below 150°C per the transient thermal impedance curve Z_thJC(t_p).
