Product details
Overview
IRFH5106TRPBF from Infineon Technologies (formerly International Rectifier) is a 60 V, 100 A N-channel PQFN 5×6 mm power MOSFET optimized for high-efficiency secondary-side synchronous rectification and DC-DC brick applications, featuring 4.65 mΩ typical RDS(on) at VGS = 10 V, 50 nC total gate charge, and 0.5 °C/W thermal resistance to PCB.
For engineers reviewing the IRFH5106TRPBF datasheet, IRFH5106TRPBF pinout, IRFH5106TRPBF application, or IRFH5106TRPBF equivalent, key selection criteria include low-conduction-loss operation at high current density, thermal performance under bottom-side cooling, unclamped inductive switching capability, and compatibility with standard surface-mount assembly processes for high-volume power supply manufacturing.
Technical Context
This HEXFET Power MOSFET employs a trench-gate silicon process with integrated body diode, designed for hard-switched and synchronous rectifier topologies where fast turn-on/turn-off dynamics (td(on) = 8.1 ns, tf = 9.5 ns) and low Qgd/Qgs ratio reduce switching loss. Its 1.4 Ω gate resistance and 205 pF Crss support stable gate drive with minimal ringing.
The device operates across –55 °C to +150 °C junction temperature, with gate threshold voltage tightly specified (2.0–4.0 V) and negative temperature coefficient (–8.5 mV/°C), enabling predictable turn-on behavior in thermally varying environments such as server VRMs and telecom power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Supports 48 V input bus systems with 20 % margin for transient overvoltage |
| RDS(on) max @ VGS = 10 V | 5.6 mΩ - Enables ≤0.56 W conduction loss at 100 A continuous drain current |
| Qg typical | 50 nC - Determines gate driver power requirement (~1.5 mW per MHz at 15 V drive) |
| ID @ TC(Bottom) = 25 °C | 100 A - Rated for continuous operation with direct PCB copper thermal path |

| VGS(th) | 2.0–4.0 V - Ensures reliable enhancement-mode turn-on with standard 3.3 V or 5 V logic-level gate drivers |
| Qrr | 130–195 nC - Quantifies body diode reverse recovery burden in synchronous rectifier dead-time management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFH5206TRPBF | Same package, 60 V rating, but 3.7 mΩ RDS(on) typ. and 65 nC Qg | Better conduction loss at cost of higher gate drive loss and slower switching | Preferred when conduction loss dominates (e.g., <100 kHz operation), not for high-frequency sync rectification |
| SIHF5106T-E3 | TO-220AB package, identical 60 V/5.6 mΩ rating, but RθJA = 62 °C/W vs. 35 °C/W | Requires external heatsink; unsuitable for ultra-thin modules | Select only when legacy through-hole assembly or manual prototyping is required |
Compared with IRFH5106TRPBF, IRFH5206TRPBF trades higher gate charge for lower RDS(on), while SIHF5106T-E3 sacrifices thermal performance and board area for mechanical robustness and serviceability-making the original optimal for space-constrained, high-efficiency surface-mount power stages.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
At TC(Bottom) = 100 °C, the IRFH5106TRPBF supports 17 A continuous drain current with VGS = 10 V, as defined in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PQFN package under realistic PCB copper area and airflow conditions, not silicon capability alone.
Does this MOSFET require a gate resistor for stability?
Yes-a 5–10 Ω external gate resistor is recommended to dampen parasitic oscillation caused by trace inductance interacting with the device's 1.4 Ω intrinsic RG and 205 pF Crss. Layout-dependent ringing has been observed above 200 kHz without series gate resistance, especially in high-di/dt synchronous rectifier configurations.
Can IRFH5106TRPBF be used in avalanche mode repeatedly?
No-its 96 mJ single-pulse avalanche energy rating (EAS) applies only to non-repetitive, transient events. The datasheet does not specify repetitive avalanche SOA, and repeated unclamped inductive switching will cause cumulative junction degradation due to localized hot-spot formation and thermal runaway.
Is the body diode suitable for freewheeling in discontinuous conduction mode?
Yes-the body diode exhibits 1.3 V forward voltage at 50 A and 28–42 ns reverse recovery time (trr), making it viable for DCM flyback or LLC resonant converter freewheeling. However, its Qrr of 130–195 nC necessitates careful dead-time tuning to avoid cross-conduction losses in synchronous rectifier implementations.
