Product details

Overview

IRFP4228PBF from Infineon Technologies (formerly International Rectifier) is a 150 V, 170 A, 12 mΩ N-channel enhancement-mode power MOSFET in TO-247AC package, optimized for plasma display panel (PDP) sustain, energy recovery, and pass-switch circuits. It features low EPULSE rating (≤120 µJ at 100°C), 71 nC total gate charge, and 175°C maximum junction temperature.

For engineers reviewing the IRFP4228PBF datasheet, IRFP4228PBF pinout, IRFP4228PBF application, or IRFP4228PBF equivalent, key selection criteria include repetitive avalanche capability (EAS = 900 mJ), fast switching (tr = 59 ns, tf = 33 ns), low RDS(on) temperature coefficient, and robust body diode performance (trr = 76–110 ns, Qrr = 230–350 nC).

Technical Context

This MOSFET employs advanced HEXFET® process technology with planar cell structure and optimized doping profile to achieve low on-resistance while maintaining high avalanche ruggedness. Its gate threshold voltage (3.0–5.0 V) and negative temperature coefficient of VGS(th) (−14 mV/°C) support stable current sharing in parallel configurations.

The device integrates a co-packaged, fast-recovery body diode with low forward voltage (VSD ≤ 1.3 V) and controlled reverse recovery characteristics-critical for unclamped inductive switching in PDP sustain drivers. Thermal design is enabled by low RθJC (0.49 °C/W) and validated transient thermal impedance data up to 100 ms.

Key Specifications

Parameter	Value and Actual Design Meaning
VDS (min)	150 V - Withstands DC bus voltages up to 150 V in PDP sustain stages without breakdown.
RDS(on) typ. @ 10 V	12 mΩ - Enables <1.2 W conduction loss at 100 A drain current, reducing heatsink requirements.
ID @ TC = 100°C	170 A - Sustains continuous high-current operation in energy recovery circuits at elevated case temperatures.
Qg typ.	71 nC - Supports fast turn-on with moderate gate drive strength (e.g., 1–2 A peak), minimizing switching losses.
EAS (single pulse)	900 mJ - Absorbs unclamped inductive energy during fault conditions without failure, enabling simplified protection design.
tr / tf	59 ns / 33 ns - Enables >1 MHz switching in resonant sustain topologies with minimal overlap loss.
TJ max	175°C - Allows operation in thermally constrained PDP chassis environments with derated power handling.

Pinout & Package

IRFP4228PBF is housed in a TO-247AC package with isolated tab (drain-connected), standard lead configuration, and screw-mount mechanical interface (6-32 or M3, 1.1 N·m torque). The package provides low thermal resistance (RθJC = 0.49 °C/W) and supports high-current PCB mounting via solder or clamp.

Pin/Terminal	Circuit Role	Design Meaning
G (Gate)	Control terminal	Receives 10 V logic-level gate drive; requires 71 nC charge for full enhancement; sensitive to ESD (±30 V max).
D (Drain)	High-side power output	Connected to PDP sustain bus (150 V); electrically tied to metal tab; carries full load current and avalanche energy.
S (Source)	Power return / reference	Serves as local ground reference for gate drive; carries 170 A continuous; internal source inductance (7.5 nH) affects switching ringing.

Key Features

Feature	Design Value
Low EPULSE rating	≤120 µJ at 100°C - Reduces localized heating during short-circuit events in PDP sustain switches, improving cycle life.
Repetitive avalanche capability	EAR rated - Enables reliable operation under repeated inductive turn-off stress without external snubbers in energy recovery paths.
Fast body diode	trr = 76–110 ns, Qrr = 230–350 nC - Minimizes reverse recovery loss and dv/dt-induced shoot-through in half-bridge sustain drivers.
High-temperature ruggedness	TJ max = 175°C with validated SOA up to 100 µs - Supports compact thermal design in sealed PDP enclosures with limited airflow.

Applications

PDP Sustain Driver

Use Scenario: Driving row/column electrodes in plasma display panels to maintain pixel illumination during sustain phase.

IC Role / Device Role / Timing Role: High-current, high-voltage switch toggling at 200–500 kHz to apply AC sustain pulses across plasma cells.

Use Value: Low RDS(on) and fast switching minimize conduction + switching losses, enabling >90% efficiency in multi-kW sustain modules.

Use Scenario: Recovering and recycling reactive energy stored in PDP panel capacitance between sustain pulses.

IC Role / Device Role / Timing Role: Bidirectional energy transfer switch operating in resonant LLC or ZVS topology with body diode conduction.

Use Value: Low Qrr and soft reverse recovery reduce diode switching loss and EMI, extending capacitor lifetime in high-cycle applications.

PDP Pass Switch

Industrial DC Bus Protection

IC Role / Device Role / Timing Role: Low-loss, high-reliability series pass element activated for <100 ms per frame.

Use Value: 170 A continuous rating at 100°C case temperature enables compact single-device implementation without paralleling.

Use Scenario: Overcurrent protection and crowbar function in 100–150 V industrial DC distribution systems.

Use Value: 900 mJ single-pulse avalanche energy rating allows safe absorption of inductive kickback without external TVS or fusing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STW100N15F7	150 V, 100 A, RDS(on) = 11.5 mΩ, Qg = 65 nC, TO-247 long leads	Lower current rating; optimized for motor drives, not PDP-specific avalanche testing	Preferred where lower gate charge and tighter RDS(on) tolerance are critical, but requires verification of avalanche robustness in PDP waveforms.
IXFH120N15T2	150 V, 120 A, RDS(on) = 12.5 mΩ, Qg = 82 nC, TO-247 non-isolated tab	Higher Qg increases gate drive loss; non-isolated tab limits layout flexibility in grounded-drain PDP designs	Acceptable for lower-frequency (<100 kHz) energy recovery where thermal margin exceeds 20°C.

Compared with STW100N15F7 and IXFH120N15T2, IRFP4228PBF delivers superior repetitive avalanche endurance and PDP-validated EPULSE performance-making it the only option qualified for sustained 200+ kHz unclamped inductive switching in production plasma displays.

FAQ

What is the maximum recommended gate resistor for reliable switching?

A 5.1 Ω gate resistor is specified in the datasheet for turn-off delay (td(off) = 24 ns) and fall time (tf = 33 ns) measurements at TJ = 25°C and 100°C. Using >10 Ω increases switching losses and may cause shoot-through in half-bridge configurations due to slower turn-off. For PDP sustain, 2.5–5.1 Ω is optimal.

Does IRFP4228PBF require a negative gate turn-off voltage?

No. The device operates reliably with 0 V gate turn-off. Its gate threshold voltage (3.0–5.0 V) and low leakage (IGSS ≤ ±100 nA) ensure clean turn-off without negative bias. Negative voltage is unnecessary and not recommended, as VGS rating is only ±30 V.

Can IRFP4228PBF be paralleled for higher current capacity?

Yes-its negative RDS(on) temperature coefficient (dRDS(on)/dTJ < 0) enables inherent current sharing. Parallel operation requires matched gate drive layout, identical source inductance (<1 nH difference), and thermal coupling. Derate total current by 15% for 2× devices and 25% for 3× or more.

Is the TO-247AC package electrically isolated?

Yes-the TO-247AC variant has an electrically isolated metal tab (drain-connected but insulated from mounting surface). This allows direct heatsink mounting without insulating pads when the drain is at system ground potential, simplifying thermal design in PDP sustain H-bridge layouts.
