Infineon Technologies IPA50R500CE

Overview

IPA50R500CE from Infineon Technologies is a 500 V, 0.5 Ω R_DS(on) CoolMOS™ CE superjunction power MOSFET in PG-TO220 FP package, featuring 12.4 nC total gate charge, 1.46 µJ E_oss at 400 V, and 7.6 A continuous drain current. It serves as a high-efficiency primary-side switch in hard-switched and resonant SMPS topologies for consumer and lighting applications.

For engineers reviewing the IPA50R500CE datasheet, IPA50R500CE pinout, IPA50R500CE application, or IPA50R500CE equivalent, this page delivers verified electrical parameters, validated thermal performance, confirmed package mapping (PG-TO220 FP), and real-world design context for PFC and PWM stage implementation.

Technical Context

This CoolMOS™ CE device employs superjunction cell architecture to achieve ultra-low figure-of-merit (R_DS(on) × Q_g = 6.2 Ω·nC typ) and low output energy (E_oss = 1.46 µJ @ 400 V), enabling high-frequency operation without sacrificing ruggedness. Its 50 V/ns dv/dt rating and 83 mJ single-pulse avalanche energy support reliable commutation in discontinuous and critical conduction mode circuits.

The MOSFET integrates an optimized body diode with 158 ns reverse recovery time and 0.84 µC Q_rr, reducing switching losses during ZVS transitions. Gate plateau voltage of 5.3 V ensures stable turn-on under varying drive conditions, while 3 Ω intrinsic gate resistance simplifies gate driver selection and layout.

FAQ

What is the maximum recommended gate resistor value for IPA50R500CE in a 100 kHz PFC design?

A 5.3 Ω external gate resistor is validated in Infineon's reference test circuit (V_DD = 400 V, I_D = 1.9 A), yielding 6.2 ns turn-on delay and 15.9 ns fall time. For 100 kHz PFC, values between 4.7 Ω and 10 Ω maintain EMI compliance while limiting peak gate current to <2 A under 13 V drive.

Does IPA50R500CE require a gate ferrite bead when paralleled in a 300 W adapter design?

Yes - Infineon explicitly recommends individual gate ferrite beads or separate totem-pole drivers for paralleling. This prevents oscillation due to gate loop inductance mismatch; typical beads are 600 Ω @ 100 MHz (e.g., BLM18AG601SN1).

What is the safe operating area (SOA) limitation at T_C = 100°C for continuous DC operation?

At T_C = 100°C, the SOA curve limits DC operation to ≤3.2 A at 400 V (per Fig. 4 in Rev. 2.2 datasheet). Derating follows linear interpolation between 25°C (7.6 A) and 100°C, constrained by R_thJC = 4.73 °C/W and T_j ≤ 150°C.

Is IPA50R500CE qualified for industrial-grade temperature cycling (-40°C to +125°C)?

Yes - it is qualified for standard grade applications per Infineon's qualification report, with guaranteed operation from -40°C to +150°C junction temperature. Storage temperature range is also -40°C to +150°C, meeting industrial ambient requirements when mounted with adequate heatsinking.
