Product details
Overview
IRFIBC30GPBF from Vishay Siliconix is a 600 V, 2.5 A N-channel power MOSFET in TO-220 FULLPAK package with isolated tab, 2.5 kVRMS isolation rating, and 2.2 Ω RDS(on) at VGS = 10 V. It serves as a high-voltage switching device in offline SMPS, AC-DC adapters, and industrial motor controls where galvanic isolation and avalanche ruggedness are required.
For engineers reviewing the IRFIBC30GPBF datasheet, IRFIBC30GPBF pinout, IRFIBC30GPBF application, or IRFIBC30GPBF equivalent, this part delivers verified 250 mJ single-pulse avalanche energy, 3.0 V/ns peak diode recovery dV/dt, and low thermal resistance (RthJC = 3.6 °C/W) - critical for reliable high-voltage flyback and forward converter designs.
Technical Context
This third-generation power MOSFET integrates an isolated TO-220 FULLPAK package with internal drain and source inductances of 4.5 nH and 7.5 nH respectively, enabling predictable switching behavior in hard-switched topologies. Its gate charge profile (Qg = 31 nC, Qgd = 17 nC) supports efficient drive with standard 12 Ω gate resistors under 300 V bus conditions.
The device features a body diode with trr = 400–810 ns and Qrr = 2.1–4.2 μC at TJ = 25 °C, optimized for snubberless operation in discontinuous conduction mode (DCM) converters. Its VGS(th) range of 2.0–4.0 V ensures robust turn-on margin across temperature while maintaining noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - supports 400 VAC input rectified systems with 50 % safety margin |
| RDS(on) | 2.2 Ω @ VGS = 10 V - enables ≤ 8.25 W conduction loss at 2.5 A continuous ID |
| Qg / Qgd | 31 nC / 17 nC - determines gate drive power and Miller-induced switching delay |
| EAS | 250 mJ - withstands unclamped inductive energy without failure in flyback snubberless designs |
| RthJC | 3.6 °C/W - allows 35 W dissipation with ≤ 126 °C junction rise above 25 °C case |
| dV/dt | 3.0 V/ns - sustains fast voltage transients during diode reverse recovery without false turn-on |
| ID (TC = 100 °C) | 1.6 A - defines usable current derating in enclosed industrial enclosures |
Pinout & Package
IRFIBC30GPBF uses the TO-220 FULLPAK package: isolated plastic-molded outline with electrically insulated metal tab (2.5 kVRMS, 60 s), 4.8 mm sink-to-lead creepage, and M3 mounting screw compatibility. Tab is internally connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G (Gate) | Control electrode | Receives 10 V logic-level drive; threshold 2.0–4.0 V ensures clean turn-on at room and elevated temperature |
| D (Drain) | High-side power terminal | Internally bonded to isolated tab; carries full load current and avalanche energy path |
| S (Source) | Reference and return node | Provides low-inductance return path; LS = 7.5 nH impacts diode commutation ringing |
Key Features
| Feature | Design Value |
|---|---|
| Isolated TO-220 FULLPAK | Eliminates need for mica insulator and shoulder washer - reduces assembly cost and thermal interface resistance |
| 2.5 kVRMS isolation | Meets reinforced insulation requirements per IEC 60950-1 and IEC 62368-1 for primary-secondary barrier |
| Low RthJC (3.6 °C/W) | Enables direct heatsink mounting with <1.5 K/W total thermal path to ambient in forced-air systems |
| Dynamic dV/dt rating (3.0 V/ns) | Prevents spurious turn-on during high-speed switching in bridge-leg configurations |
| Avalanche-rated (EAS = 250 mJ) | Supports reliable operation in unclamped inductive switching without external snubbers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage isolated MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STW20NK60Z | 600 V, 20 A, RDS(on) = 0.3 Ω, non-isolated TO-247; no isolation rating | Requires external insulator; higher current but unsuitable for reinforced insulation layouts | Select when higher current and lower RDS(on) are prioritized over isolation integration |
| IXTP50N10P | 100 V, 50 A, TO-220 non-isolated; RDS(on) = 0.022 Ω; no HV isolation or avalanche rating | Only suitable for low-voltage DC-DC stages; cannot replace in primary-side HV positions | Use only in secondary-side synchronous rectification or low-VDS bus applications |
Compared with STW20NK60Z and IXTP50N10P, the IRFIBC30GPBF uniquely combines certified 2.5 kVRMS isolation, 600 V rating, and 250 mJ avalanche capability in a single TO-220 footprint - eliminating insulator BOM items and enabling compact, safety-compliant primary-side designs.

FAQ
What is the isolation voltage rating of the IRFIBC30GPBF and how is it validated?
The IRFIBC30GPBF provides 2.5 kVRMS isolation between drain (tab) and leads for 60 seconds at 60 Hz, per IEC 60950-1 test conditions. This rating is achieved through proprietary molding compound and internal geometry in the TO-220 FULLPAK package - not via external hardware. The IRFIBC30GPBF datasheet (S21-0976-Rev. C) confirms this value in the FEATURES section and ABSOLUTE MAXIMUM RATINGS table.
Does the IRFIBC30GPBF have a built-in body diode, and what are its key recovery parameters?
Yes, the IRFIBC30GPBF integrates a monolithic body diode with trr = 400–810 ns and Qrr = 2.1–4.2 μC at TJ = 25 °C, IF = 3.6 A, and dI/dt = 100 A/μs. These values are measured per JEDEC standards and published in the SPECIFICATIONS table on page 2 of the IRFIBC30GPBF datasheet. The diode supports snubberless operation in DCM flyback converters.
Can the IRFIBC30GPBF be used in avalanche mode repeatedly, and what are the limits?
The IRFIBC30GPBF is rated for repetitive avalanche with IAR = 2.5 A and EAR = 3.5 mJ, defined under pulse conditions limited by junction temperature. This is distinct from its single-pulse rating of EAS = 250 mJ. Operation within these repetitive limits requires strict thermal management and pulse timing control per Figure 12c in the IRFIBC30GPBF datasheet.
What is the gate threshold voltage range for the IRFIBC30GPBF, and how does it affect drive design?
The IRFIBC30GPBF has a VGS(th) range of 2.0–4.0 V at ID = 250 μA, ensuring reliable turn-on with standard 10 V gate drivers across temperature. This wide threshold avoids marginal switching near 5 V logic levels and maintains noise margin in noisy industrial environments. The IRFIBC30GPBF's typical gfs = 2.2 S further supports stable gain in gate-controlled applications.
How does the TO-220 FULLPAK package of the IRFIBC30GPBF differ from standard TO-220 in thermal and safety performance?
The TO-220 FULLPAK package of the IRFIBC30GPBF replaces the conductive metal tab of standard TO-220 with an electrically isolated, thermally conductive molded tab - delivering 2.5 kVRMS isolation and 4.8 mm creepage. Its RthJC = 3.6 °C/W matches or exceeds standard TO-220, while eliminating insulator hardware. This is confirmed in the PACKAGE INFORMATION document 91359 for IRFIBC30GPBF.
