Product details

Overview

IRFS3107-7PPBF from Infineon Technologies is a 75V, 260A N-channel HEXFET Power MOSFET in D2PAK-7L package, optimized for high-current synchronous rectification and hard-switched SMPS topologies. It delivers 2.1mΩ typical R_DS(on), 160nC total gate charge, and enhanced avalanche ruggedness (1060mJ E_AS), enabling robust operation in UPS and telecom power stages.

For engineers reviewing the IRFS3107-7PPBF datasheet, IRFS3107-7PPBF pinout, IRFS3107-7PPBF application, or IRFS3107-7PPBF equivalent, key selection criteria include its 2.6mΩ max R_DS(on) at 10V V_GS, 1060A pulsed diode current capability, 1150pF C_{oss eff.(ER)}, and SOA-limited 240A package-rated continuous drain current under PCB-mount conditions.

Technical Context

This MOSFET employs planar silicon HEXFET architecture with optimized cell pitch and trench-assisted body diode design to achieve simultaneous low conduction loss and fast, soft reverse recovery (t_rr = 52ns, Q_rr = 110nC at 25°C). Its gate threshold voltage (2.0–4.0V) and 2.1Ω internal gate resistance support stable drive in high-di/dt environments.

The device is characterized for unclamped inductive switching up to 160A I_AS, with thermal-limited single-pulse avalanche energy of 1060mJ. Its R_θJC = 0.40°C/W enables direct heatsink mounting, and C_iss/C_oss ratio (9200pF/850pF) supports high-frequency ZVS/ZCS implementation in resonant converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	75V - Maximum blocking voltage before avalanche onset; sets upper limit for bus voltage in 48V systems.
R_DS(on) typ.	2.1mΩ - Enables <1.5W conduction loss at 160A DC, critical for >98% efficiency in high-current synchronous rectifiers.

Pinout & Package

IRFS3107-7PPBF uses the surface-mount D2PAK-7L (TO-263-7) package with exposed drain pad for thermal and electrical performance. The 7-pin layout integrates three parallel source terminals and two auxiliary sense pins for Kelvin source connection.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3 (S)	Source (Kelvin-sensed)	Three dedicated low-inductance source paths reduce measurement error in current sensing and improve gate control stability.
4, 5, 6 (D)	Drain (common tab)	Internally paralleled drain connections tied to large copper tab for minimal R_DS(on) and thermal resistance.
7 (G)	Gate	Standard gate input; 2.1Ω internal resistance damps ringing without external gate resistor in most layouts.

Key Features

Feature	Design Value
Enhanced body diode dV/dt capability	Supports >1420V/µs commutation without parasitic turn-on, enabling reliable operation in high-di/dt synchronous rectifier circuits.
Characterized avalanche SOA	Guarantees 1060mJ single-pulse energy handling at T_J = 175°C, eliminating need for external snubbers in overvoltage transients.
Low C_{oss eff.(TR)}	1500pF - Time-related output capacitance minimizes dead-time losses and improves light-load efficiency in resonant topologies.
Lead-free and RoHS-compliant	Meets IPC-J-STD-020 moisture sensitivity level 3 (MSL3), supporting standard reflow profiles without popcorn risk.
Thermally optimized D2PAK-7L	0.40°C/W R_θJC enables 260W dissipation with 100°C case-to-ambient delta, suitable for compact industrial power modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N7F3AG	75V, 220A, 2.3mΩ R_DS(on), 190nC Q_g, DFN8 5x6 package	Lacks Kelvin source pins; higher R_θJA (300°C/W) limits power density in compact designs	Preferred for space-constrained consumer PSUs where thermal budget permits lower current rating.
IXFH320N075T2	75V, 320A, 1.8mΩ R_DS(on), 320nC Q_g, TO-247-3L package	Higher gate charge increases driver complexity; larger through-hole footprint incompatible with SMT-only lines	Chosen when maximum current headroom and discrete heatsink mounting are prioritized over assembly cost.

Compared with STL220N7F3AG and IXFH320N075T2, IRFS3107-7PPBF uniquely balances ultra-low R_DS(on), Kelvin source sensing, and SMT-compatible D2PAK-7L packaging-making it optimal for high-density, high-reliability telecom and industrial SMPS where board area, thermal management, and current-sense accuracy are co-constrained.

FAQ

What is the maximum allowable case temperature for continuous operation?

The IRFS3107-7PPBF supports continuous operation up to 175°C junction temperature. With R_θJC = 0.40°C/W, the maximum sustainable case temperature is 150°C when dissipating 62.5W-calculated as T_Jmax − (P_D × R_θJC). Derating begins above 25°C ambient per the linear derating factor of 3.2W/°C shown in the datasheet.

Does the D2PAK-7L package require special PCB layout considerations?

Yes-the D2PAK-7L requires a minimum 1.5-inch² exposed copper pour on the drain pad layer, connected via ≥8 thermal vias (0.3mm diameter) to inner ground planes. The Kelvin source pins (pins 1–3) must be routed with matched-length traces to the current-sense amplifier to maintain <1% gain error at 200A di/dt.

How does the body diode's reverse recovery performance compare to discrete Schottky alternatives?

At 160A and 25°C, the IRFS3107-7PPBF body diode achieves t_rr = 52ns and Q_rr = 110nC-comparable to 120V Schottky diodes rated for 200A. Unlike Schottky devices, it maintains consistent recovery characteristics up to 125°C (t_rr = 63ns), avoiding thermal runaway in high-ambient environments.

Can this MOSFET be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(on) (0.083V/°C) ensures inherent current sharing. Parallel operation requires matched gate drive impedance (<0.5Ω difference), identical PCB trace lengths, and individual 10Ω gate resistors to suppress oscillation. Up to four units have been validated in 10kW server PSU reference designs.
