Product details
Overview
IRFIBC40GPbF from Vishay Siliconix is a 600 V, 3.5 A N-channel power MOSFET in TO-220 FULLPAK package with 1.2 Ω RDS(on) at VGS = 10 V, 60 nC total gate charge, and 2.5 kVRMS isolation rating-designed for high-voltage DC-DC converters and industrial motor control where creepage distance and thermal performance are critical.
For engineers reviewing the IRFIBC40GPbF datasheet, IRFIBC40GPbF pinout, IRFIBC40GPbF application, or IRFIBC40GPbF equivalent, this device's isolated package, avalanche energy rating (500 mJ), dV/dt immunity (3.0 V/ns), and sink-to-lead creepage (4.8 mm) are key selection criteria for safety-critical switching designs.
Technical Context
This third-generation high-voltage MOSFET features an integrated body diode with 470–940 ns reverse recovery time and 4.0–7.9 μC Qrr, enabling robust unclamped inductive switching. Its isolated TO-220 FULLPAK construction eliminates external insulation hardware while delivering 3.1 °C/W junction-to-case thermal resistance.
The device supports repetitive avalanche operation up to 3.5 A and 4.0 mJ, with dynamic dV/dt capability rated at 3.0 V/ns under specified test conditions. Gate threshold voltage ranges from 2.0 V to 4.0 V, ensuring stable turn-on across temperature and process variation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP6NK60ZFP | 600 V, 5.5 A, RDS(on) = 1.2 Ω, Zener-protected gate, but no isolation rating or creepage specification | Requires external insulation hardware for heatsink mounting; not certified for reinforced insulation | Prefer when higher continuous current is needed and isolation is handled at board level |
| FQP6N60C | 600 V, 5.4 A, RDS(on) = 1.3 Ω, standard TO-220 (non-isolated), lower Qg (42 nC) | Lacks 2.5 kVRMS isolation and 4.8 mm creepage; unsuitable for safety-critical mains-connected designs | Select when cost sensitivity outweighs isolation requirements and thermal design allows non-isolated mounting |
Compared with STP6NK60ZFP and FQP6N60C, the IRFIBC40GPbF uniquely delivers certified high-voltage isolation in a drop-in TO-220 footprint-enabling simplified compliance with IEC 62368-1 while maintaining competitive RDS(on) and avalanche ruggedness.

FAQ
What is the maximum continuous drain current for IRFIBC40GPbF at 100 °C case temperature?
The IRFIBC40GPbF supports 2.2 A continuous drain current at TC = 100 °C, derated linearly from 3.5 A at 25 °C using a 0.32 W/°C factor. This rating assumes proper heatsinking and accounts for junction temperature limits of 150 °C. The IRFIBC40GPbF datasheet specifies these values in the Absolute Maximum Ratings table under "Continuous drain current".
Does IRFIBC40GPbF have a built-in body diode, and what are its key parameters?
Yes, the IRFIBC40GPbF integrates a body diode with typical forward voltage of 1.5 V at 3.5 A and 25 °C, reverse recovery time of 470–940 ns, and reverse recovery charge of 4.0–7.9 μC. These values are measured under standardized conditions (TJ = 25 °C, IF = 6.2 A, dI/dt = 100 A/μs) and directly impact performance in freewheeling and resonant applications. The IRFIBC40GPbF body diode characteristics are detailed in the "Drain-Source Body Diode Characteristics" section of the datasheet.
Can IRFIBC40GPbF be used as a direct replacement for standard TO-220 MOSFETs without layout changes?
No-while the IRFIBC40GPbF shares the same outline dimensions as standard TO-220, its TO-220 FULLPAK variant features an electrically isolated metal tab. This allows direct heatsink mounting without insulating hardware, but requires verification that the PCB pad layout accommodates the internal isolation structure and creepage requirements. The IRFIBC40GPbF must not be substituted for non-isolated TO-220 devices in safety-critical designs without re-evaluation of insulation coordination.
What is the gate-source voltage limit for IRFIBC40GPbF, and why is it important?
The IRFIBC40GPbF has a gate-source voltage limit of ±20 V, beyond which permanent gate oxide damage may occur. Operating within this range ensures reliable threshold stability and avoids gate leakage increase or catastrophic failure. Drive circuits must clamp transients and avoid overshoot-especially during paralleling or high-dI/dt switching. This specification is explicitly defined in the Absolute Maximum Ratings table of the IRFIBC40GPbF datasheet.
How does the 2.5 kVRMS isolation rating of IRFIBC40GPbF impact system-level safety certification?
The 2.5 kVRMS isolation rating (60 s, 60 Hz) of the IRFIBC40GPbF satisfies reinforced insulation requirements for basic functional isolation in many industrial power systems per IEC 62368-1 and IEC 61800-5-1. It reduces reliance on external barriers and simplifies creepage/clearance validation-but full system certification still requires evaluation of PCB layout, heatsink grounding, and enclosure design. The IRFIBC40GPbF isolation performance is verified per Vishay's internal test protocol documented in S21-0976.
