Infineon Technologies IRFH5220TRPBF

Overview

IRFH5220TRPBF from Infineon Technologies (formerly International Rectifier) is a 200 V, 20 A N-channel enhancement-mode HEXFET Power MOSFET in PQFN 5×6 mm package with 99.9 mΩ R_DS(on) at V_GS = 10 V, 20 nC total gate charge, and 1.2 °C/W junction-to-case (bottom) thermal resistance. It is engineered for high-efficiency secondary-side synchronous rectification in isolated DC-DC converters.

For engineers reviewing the IRFH5220TRPBF datasheet, IRFH5220TRPBF pinout, IRFH5220TRPBF application, or IRFH5220TRPBF equivalent, key selection criteria include its low R_DS(on), industry-standard PQFN pinout, MSL1 industrial qualification, and validated performance in 100–200 V DC-DC brick and boost converter topologies.

Technical Context

This device operates as a unidirectional power switch with a body diode rated for 5.8 A continuous source current and 39–59 ns reverse recovery time. Its gate threshold voltage (3.0–5.0 V) and negative temperature coefficient (−11 mV/°C) enable stable turn-on across −55 to +150 °C operating range.

The MOSFET features a split thermal path: 1.2 °C/W to PCB via bottom thermal pad and 15 °C/W to top surface, supporting dual-side cooling in high-density power modules. Avalanche-rated (290 mJ single-pulse) and 100% R_G tested, it sustains repetitive unclamped inductive switching stress in motor drive inverters.

FAQ

What is the maximum continuous drain current at 100 °C case temperature?

The IRFH5220TRPBF supports 13 A continuous drain current when the bottom case temperature is maintained at 100 °C, as specified in the Absolute Maximum Ratings table. This value assumes optimal PCB thermal design with ≥1 in² 2-oz copper pour directly under the thermal pad and no airflow limitation.

Does this MOSFET require a gate resistor for safe operation?

Yes-a gate resistor (typically 2.2–10 Ω) is required to dampen gate ringing and limit peak gate current during switching. Although the device has a nominal R_G of 2.3 Ω, external resistance controls dV/dt and prevents spurious turn-on caused by Miller capacitance coupling in high-di/dt circuits.

Can IRFH5220TRPBF be used in avalanche mode repeatedly?

No-it is rated for single-pulse avalanche energy only (290 mJ at T_J = 25 °C). Repetitive avalanche operation is not characterized or guaranteed; sustained inductive switching must be managed via snubbers, clamping, or topology-level protection to avoid cumulative die degradation.

Is the PQFN 5×6 package compatible with standard reflow profiles?

Yes-the IRFH5220TRPBF is MSL1 qualified and compatible with IPC/JEDEC J-STD-020D-compliant lead-free reflow profiles, including peak temperatures up to 260 °C for ≤60 seconds. No pre-baking is required, and the package withstands standard vapor phase and convection reflow processes.
