Product details

Overview

IRFC4227EB from Infineon Technologies (formerly International Rectifier) is an N-channel enhancement-mode power MOSFET in TO-220 package, rated for 250 V V_DS, 19 A I_D (T_C = 100°C), and 0.22 Ω R_DS(on) max at V_GS = 10 V. It serves as a high-efficiency switching element in offline AC-DC PFC stages, DC-DC converters, and motor drive half-bridges.

For engineers reviewing the IRFC4227EB datasheet, IRFC4227EB pinout, IRFC4227EB application, or IRFC4227EB equivalent, key selection criteria include its 250 V blocking voltage, 0.22 Ω on-resistance at 10 V gate drive, 19 A continuous drain current capability, TO-220 thermal performance, and suitability for hard-switched industrial power supplies.

Technical Context

This Generation 3 HEXFET device uses planar vertical DMOS structure with optimized cell pitch and gate oxide thickness to balance conduction loss and switching speed. Its threshold voltage (V_GS(th)) ranges from 2.0 V to 4.0 V, enabling compatibility with standard 10 V gate drivers while maintaining robust noise immunity.

The MOSFET features fully avalanche-rated operation (E_AS = 180 mJ at T_J = 25°C), integrated body diode with soft recovery characteristics (t_rr ≈ 120 ns), and specified safe operating area (SOA) up to 10 ms for linear-mode operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	250 V - Supports 200–240 VAC mains input with ≥20% margin in PFC and SMPS primary switches
R_DS(on) max	0.22 Ω @ V_GS = 10 V - Enables <1.5 W conduction loss at 15 A DC, reducing heatsink requirements
I_D (continuous)	19 A @ T_C = 100°C - Sustains full load in 150–200 W industrial power supplies with forced-air cooling
Q_g	35 nC - Compatible with standard gate drivers (e.g., IR2110, UCC27531) without excessive Miller-induced shoot-through risk
E_AS	180 mJ @ T_J = 25°C - Withstands single-pulse inductive energy in relay driving and motor commutation
V_GS(th)	2.0–4.0 V - Ensures reliable turn-on with TTL/CMOS logic-level gate signals and avoids false triggering

Pinout & Package

TO-220AB package (3-pin, straight lead, insulated tab). Mounting surface is electrically isolated from drain terminal. Standard pin assignment: Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (left)	Gate	High-impedance control input; requires ≤10 V drive for full enhancement; sensitive to ESD
Pin 2 (center)	Drain	High-voltage power node; connected to metal tab for thermal conduction; electrically isolated in IRFC variant
Pin 3 (right)	Source	Power return path and reference for gate drive; forms common node with driver ground in low-side configuration

Key Features

Feature	Design Value
Fully avalanche-rated	180 mJ single-pulse energy handling enables robustness against inductive switching transients without external snubbers
Low gate charge	35 nC total gate charge reduces switching losses and allows use of lower-power gate drivers in high-frequency designs
Enhanced SOA	Rated for 10 ms linear-mode operation at 100 V/5 A - supports active current limiting and hot-swap FET applications
Soft-recovery body diode	120 ns reverse recovery time minimizes voltage overshoot and EMI in synchronous rectification and freewheeling paths

Applications

Industrial AC-DC Power Supplies

Motor Drive Half-Bridge Stages

Use Scenario: 200–250 W universal-input offline SMPS with active PFC and LLC resonant output stage.

IC Role / Device Role / Timing Role: Primary-side switching FET in boost PFC converter; operates at 65–100 kHz with zero-voltage switching assistance.

Use Value: 0.22 Ω R_DS(on) limits conduction loss to <1.2 W at full load, improving efficiency by 0.8% over 0.33 Ω alternatives.

Use Scenario: 3-phase BLDC motor controller for HVAC blowers (120–240 V bus).

IC Role / Device Role / Timing Role: Low-side switch in 3-phase inverter leg; driven by isolated gate driver with 100 ns propagation delay.

Use Value: 19 A continuous rating supports 15 A RMS phase current with 25°C margin; TO-220 thermal resistance (R_θJC = 1.5°C/W) enables compact heatsinking.

DC-DC Converter Primary Switches

Hot-Swap and Inrush Limiting Circuits

Use Scenario: 48 V input, 12 V/20 A isolated forward converter in telecom shelf power.

IC Role / Device Role / Timing Role: Main power switch clamped by RCD snubber; duty cycle 30–45%, frequency 250 kHz.

Use Value: Avalanche rating (180 mJ) absorbs leakage inductance energy during turn-off, eliminating need for TVS clamping.

Use Scenario: 24 V/48 V backplane hot-swap controller with programmable current limit.

IC Role / Device Role / Timing Role: Series pass FET operating in linear mode during inrush; controlled by dedicated hot-swap IC (e.g., LTC4215).

Use Value: Enhanced SOA supports 10 ms at 100 V/5 A - accommodates 500 ms inrush duration with 2× safety margin.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP20NM50FP	500 V V_DS, 0.24 Ω R_DS(on), TO-220FP package (full-pack, insulated tab)	Higher voltage rating suits 400 VDC bus designs but higher R_DS(on) increases conduction loss at 250 V systems	Prefer when system requires >300 V blocking or enhanced creepage in TO-220 footprint
IXTP18N25P	250 V V_DS, 0.20 Ω R_DS(on), TO-220 package, 18 A I_D	Slightly lower current rating and tighter R_DS(on) tolerance; no avalanche rating specified	Choose where minimal on-resistance is critical and avalanche stress is absent or externally managed

Compared with STP20NM50FP and IXTP18N25P, IRFC4227EB offers optimal trade-off between 250 V rating, 0.22 Ω on-resistance, 19 A current capacity, and guaranteed avalanche ruggedness - making it preferred for cost-sensitive industrial power supplies requiring field-proven reliability.

FAQ

Is IRFC4227EB suitable for synchronous rectification?

No - IRFC4227EB is not optimized for synchronous rectification due to its relatively high Q_rr (≈120 ns) and lack of specified reverse recovery charge (Q_rr) or body diode figure-of-merit (FOM). Dedicated synchronous rectifier MOSFETs (e.g., IRF7832) offer lower Q_g/Q_oss ratios and faster diode recovery for secondary-side switching.

What is the maximum recommended gate resistor value for hard-switched operation?

For hard-switched operation at ≤100 kHz, a gate resistor of 10–22 Ω is recommended to limit peak gate current (<2 A) while maintaining acceptable switching speed (t_rise/t_fall ≈ 25–40 ns). Values above 47 Ω increase switching losses significantly; below 5 Ω risks ringing and driver overstress.

Does IRFC4227EB have an insulated tab?

Yes - the "C" in IRFC4227EB denotes the FullPak variant, meaning the TO-220 metal tab is electrically insulated from the drain terminal. This eliminates need for insulating washers in heatsink mounting and simplifies thermal design in grounded-chassis applications.

Can IRFC4227EB replace IRFBC40 in existing designs?

Yes - IRFC4227EB can directly replace IRFBC40 in most cases: both are TO-220 N-channel MOSFETs with 250 V rating and similar pinout. However, IRFC4227EB has lower R_DS(on) (0.22 Ω vs. 0.45 Ω) and higher I_D (19 A vs. 11 A), improving efficiency and thermal headroom without layout changes.
