Product details
Overview
IRFS3307TRLPBF from Infineon Technologies is a 75V, 120A N-channel enhancement-mode HEXFET® Power MOSFET in D2Pak (TO-263) package, optimized for high-frequency hard-switched and synchronous rectification applications with 5.0 mΩ typical RDS(on), 120 nC total gate charge, and enhanced body diode dV/dt (11 V/ns) and dI/dt capability. It delivers robust avalanche performance (510 mJ EAS) and operates up to 175°C junction temperature.
For engineers reviewing the IRFS3307TRLPBF datasheet, IRFS3307TRLPBF pinout, IRFS3307TRLPBF application, or IRFS3307TRLPBF equivalent, key selection criteria include its low conduction loss at high current, fast switching dynamics (tr = 120 ns, tf = 63 ns), body diode recovery characteristics (Qrr = 65–98 nC), and thermal resistance (RθJA = 40°C/W on PCB mount).
Technical Context
This MOSFET employs planar silicon process technology with optimized cell layout to achieve high current density and improved ruggedness against unclamped inductive switching (UIS) and repetitive avalanche stress. Its gate structure reduces Miller capacitance (Crss = 250 pF) and enables stable operation under high dV/dt (≥11 V/ns) during diode recovery.
The device integrates an intrinsic body diode with low forward voltage (VSD = 1.3 V) and controlled reverse recovery (trr = 38–57 ns), making it suitable for synchronous rectification where diode conduction and commutation losses dominate efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 75 V - Maximum drain-to-source blocking voltage; defines safe operating range in 48V bus and UPS output stages. |
| RDS(on) typ. | 5.0 mΩ @ VGS = 10 V, TJ = 25°C - Enables <1 W conduction loss at 120 A DC, critical for high-efficiency SMPS designs. |
| Qg | 120 nC max - Determines gate drive power requirement and switching speed; supports >200 kHz operation with moderate gate driver strength. |
| tr/tf | 120 ns / 63 ns - Fast edge rates reduce switching transition time, minimizing overlap loss in hard-switched topologies. |
| EAS | 510 mJ - Single-pulse avalanche energy rating ensures reliability during transient overvoltage events without external snubbers. |
| Coss eff. (TR) | 700 pF - Time-related effective output capacitance used to calculate turn-off delay and resonant behavior in LLC or phase-shifted full-bridge converters. |
| VSD | 1.3 V max - Low body diode forward drop reduces conduction loss during freewheeling, improving synchronous rectifier efficiency. |
Pinout & Package
D2Pak (TO-263) surface-mount package with isolated tab (drain-connected), designed for high-current PCB mounting using thermal pad and solder reflow. Thermal resistance RθJA = 40°C/W on FR-4 PCB (1" square).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal (S) | Low-side reference node; connects to power ground or synchronous rectifier return path; carries full load current. |
| Pin 2 (Gate) | Control input (G) | High-impedance MOSFET gate; requires 10 V for full enhancement; sensitive to ESD and ringing due to Qg = 120 nC. |
| Pin 3 (Drain) | Power output (D) | Connected to internal die backside; electrically tied to exposed copper tab; must be isolated from heatsink unless referenced to same potential. |
Key Features
| Feature | Design Value |
|---|---|
| Enhanced avalanche ruggedness | 510 mJ single-pulse EAS with validated thermal failure model - eliminates need for external clamping in UPS and motor drive inductive loads. |
| Optimized body diode recovery | Qrr = 65–98 nC and dV/dt = 11 V/ns - reduces voltage overshoot and EMI during commutation in synchronous buck and LLC converters. |
| Low Coss with defined energy equivalence | Coss eff. (ER) = 570 pF - enables accurate calculation of turn-off energy loss (Eoff ≈ ½·Coss·VDS²) in high-frequency designs. |
| Thermally robust construction | RθJC = 0.61°C/W - supports >100 W continuous power dissipation with minimal heatsink when mounted on 1"² copper area. |
| Lead-free and RoHS-compliant | Meets JEDEC J-STD-020 moisture sensitivity level 1 - allows standard reflow profiles without baking or special handling. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-ruggedness N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N7F3AG | RDS(on) = 3.2 mΩ typ., Qg = 150 nC, VDSS = 75 V, DFN8 5×6 mm package | Lower RDS(on) improves conduction loss but higher Qg increases gate drive loss; smaller footprint limits thermal mass. | Prefer for space-constrained, air-cooled telecom modules where board area is premium and gate drive capability is available. |
| IXFH120N075T2 | RDS(on) = 5.5 mΩ typ., Qg = 105 nC, VDSS = 75 V, TO-247AC package | Higher RDS(on) but lower Qg and superior RθJC = 0.45°C/W; larger through-hole package supports higher mechanical reliability. | Prefer for industrial UPS and motor drives requiring maximum thermal margin and vibration resistance in harsh environments. |
Compared with STL220N7F3AG and IXFH120N075T2, IRFS3307TRLPBF offers the best balance of low RDS(on), moderate Qg, and proven D2Pak thermal performance on PCB - ideal for high-volume, cost-sensitive server and telecom power supplies where surface-mount assembly and thermal pad integration are standard.

FAQ
What is the maximum continuous drain current for IRFS3307TRLPBF at 100°C case temperature?
The maximum continuous drain current at TC = 100°C is 84 A, derated from the 120 A rating at 25°C using the linear derating factor of 1.3 W/°C and thermal resistance RθJC = 0.61°C/W. This reflects package-limited current rather than silicon-limited current, which remains thermally viable up to 175°C junction temperature.
Does IRFS3307TRLPBF have a fully characterized avalanche SOA?
Yes - the datasheet provides validated single-pulse avalanche energy (EAS = 510 mJ) and repetitive avalanche curves (EAR vs. IAV and temperature), derived from standardized unclamped inductive switching tests per JEDEC standards. The device is rated for safe operation within these boundaries without external protection.
Can IRFS3307TRLPBF be used in synchronous rectification with zero-voltage switching (ZVS)?
Yes - its low Coss eff. (TR) = 700 pF and controlled body diode recovery (trr = 38–57 ns, Qrr = 65–98 nC) support reliable ZVS turn-on in LLC and phase-shifted full-bridge topologies. However, ZVS initiation depends on circuit design (leakage inductance, resonant frequency), not solely on MOSFET parameters.
Is the D2Pak package of IRFS3307TRLPBF compatible with standard reflow soldering processes?
Yes - the device is qualified per JEDEC J-STD-020 Level 1 (MSL-1), meaning it can be subjected to standard lead-free reflow profiles (peak 260°C) without preconditioning or baking. The exposed drain tab requires full-solder coverage on a thermally enhanced PCB pad for optimal RθJA = 40°C/W performance.
