Product details
Overview
IRFSL4410ZPBF from Infineon Technologies (formerly International Rectifier) is a 100V, 97A N-channel HEXFET Power MOSFET in TO-262 package, optimized for high-frequency hard-switched SMPS and synchronous rectification. It features 7.2 mΩ typical RDS(on), 83 nC total gate charge, and enhanced body diode dV/dt/dI/dt capability with 390 mJ single-pulse avalanche energy rating.
For engineers reviewing the IRFSL4410ZPBF datasheet, IRFSL4410ZPBF pinout, IRFSL4410ZPBF application, or IRFSL4410ZPBF equivalent, key selection criteria include its 100V VDSS, low 0.65°C/W RθJC, robust 58A avalanche current handling, and suitability for UPS and high-efficiency DC-DC converters requiring stable conduction and fast switching.
Technical Context
This MOSFET employs planar silicon process with optimized cell layout to deliver improved dynamic ruggedness and fully characterized SOA across temperature. Its gate structure reduces Miller charge (Qgd = 27 nC) and enables stable operation at dV/dt up to 1.5 V/ns under clamped inductive switching.
The integrated body diode exhibits 38–57 ns reverse recovery time (trr) and 53–80 nC Qrr at 58A/85V, supporting high-frequency synchronous rectification without external Schottky replacement in many 100 kHz–500 kHz topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Maximum blocking voltage before avalanche; supports 48V/54V bus designs with 20% margin. |
| RDS(on) typ. | 7.2 mΩ @ VGS = 10 V, TJ = 25°C - Enables <1.5 W conduction loss at 60 A continuous drain current. |
| ID (Silicon Limited) | 97 A @ TC = 25°C - Sustains high-current pulses in UPS hold-up and motor drive phases. |
| Qg | 83 nC max - Determines gate driver power requirement; compatible with standard 1A peak drivers. |
| EAS | 390 mJ single-pulse - Allows unclamped inductive switching up to 58A without failure at TJ ≤ 175°C. |
| tr/tf | 52 ns / 57 ns - Supports >1 MHz switching in resonant LLC and ZVS converters with low switching loss. |
| RθJC | 0.65 °C/W - Enables 97A operation with ≤50°C case-to-junction rise using standard heatsink interface. |
Pinout & Package
IRFSL4410ZPBF is housed in a TO-262 (ISOTOP) package with three leads: Drain (D), Source (S), and Gate (G). The metal tab is electrically connected to the Drain terminal and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Tab) | Drain | Main high-side power node; electrically tied to heatsink; requires isolation if heatsink is grounded. |
| S | Source | Power return path and reference for gate drive; connects to low-side switch or ground plane. |
| G | Gate | Control input; requires 2.0–4.0 V threshold and 83 nC charge for full enhancement; sensitive to ESD. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced body diode dV/dt capability | Rated for >1.5 V/ns recovery dv/dt without parasitic turn-on in hard-switched bridge legs. |
| Full avalanche SOA characterization | Guaranteed 390 mJ single-pulse energy at IAS = 58A, enabling reliable unclamped inductive switching. |
| Low Coss eff(TR) | 690 pF - Reduces turn-off loss in high-voltage transitions; improves ZVS initiation in resonant converters. |
| Lead-free, halogen-free construction | RoHS-compliant per JEDEC J-STD-020; qualified for reflow up to 260°C (10 sec). |
| Thermally optimized TO-262 package | 0.65 °C/W RθJC - Delivers 30% lower junction temperature vs. comparable TO-220 at same ID. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current 100V power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRFB4410ZPBF (TO-220AB) | Same die, but TO-220 package with higher RθJC = 0.75°C/W and no isolated tab; 50 pcs/tube packaging. | Limited to lower-power (<75A) or forced-air-cooled designs; unsuitable for surface-mount or high-density layouts. | Select when cost sensitivity outweighs thermal performance and board space is not constrained. |
| IRFS4410ZPBF (D2Pak) | Identical electrical specs; D2Pak offers 0.50°C/W RθCS with greased sink but requires larger PCB footprint than TO-262. | Better thermal interface for high-volume automated assembly; preferred for high-reliability industrial power supplies. | Choose for automated SMT lines where thermal performance and reflow compatibility are prioritized over leaded mounting. |

FAQ
Is IRFSL4410ZPBF pin-compatible with IRFB4410ZPBF?
Yes-both share identical 3-pin TO-220/TO-262 pinout (D-G-S), with Drain on the metal tab, Gate on lead 1, and Source on lead 2. Mechanical mounting differs: TO-262 uses screw-down isolation, while TO-220 requires insulating washer. Electrical behavior is identical under same thermal conditions.
What is the maximum recommended gate resistor for 500 kHz switching?
A 10 Ω gate resistor is recommended for 500 kHz operation, balancing switching speed (tr/tf ≈ 52/57 ns) against ringing and EMI. Lower values (≤5 Ω) increase dV/dt stress and require tighter PCB layout; higher values (>22 Ω) degrade efficiency due to extended transition times.
Does IRFSL4410ZPBF support synchronous rectification in LLC resonant converters?
Yes-its 38 ns trr, 53 nC Qrr, and 1.3 V VSD enable efficient synchronous rectification in 300–600 kHz LLC converters. Gate drive must be precisely timed to avoid shoot-through; dead time should be ≥100 ns with adaptive control for variable frequency operation.
Can IRFSL4410ZPBF replace IRF1404 in existing 40V designs?
No-IRF1404 is a 40V, 202A MOSFET with different RDS(on) (4.9 mΩ) and gate charge (193 nC). IRFSL4410ZPBF's 100V rating and 7.2 mΩ RDS(on) make it unsuitable as a drop-in replacement; system-level redesign is required for voltage derating, gate drive strength, and thermal management.
