Product details
Overview
IRFBC20STRLPBF from Vishay Siliconix is a 600 V, 2.2 A N-channel surface-mount power MOSFET in D2PAK (TO-263) package, featuring 4.4 Ω RDS(on) at VGS = 10 V, 18 nC total gate charge, and full avalanche rating-designed for high-voltage flyback and offline SMPS primary-side switching.
For engineers reviewing the IRFBC20STRLPBF datasheet, IRFBC20STRLPBF pinout, IRFBC20STRLPBF application, or IRFBC20STRLPBF equivalent, this part supports stable high-temperature operation up to 150 °C, fast switching with 10 ns turn-on delay and 25 ns fall time, and robust dv/dt immunity of 3.0 V/ns-key for reliable AC-DC adapter and industrial power supply designs.
Technical Context
This third-generation power MOSFET uses planar V-groove technology optimized for high-voltage unclamped inductive switching. Its 2.5 °C/W junction-to-case thermal resistance and 40 °C/W junction-to-ambient rating (PCB mounted) enable 50 W power dissipation at TC = 25 °C while maintaining safe SOA under repetitive avalanche conditions.
The device integrates a low-Qrr (0.67–1.3 μC) body diode with 290–580 ns reverse recovery time and 1.6 V forward drop at 2.2 A, supporting quasi-resonant and discontinuous conduction mode topologies without external snubbing in cost-sensitive 20–60 W adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 600 V - Withstands full mains rectified voltage in universal-input offline converters without derating. |
| RDS(on) | 4.4 Ω @ VGS = 10 V - Enables <1.3 W conduction loss at 2.2 A DC, suitable for low-power primary switches. |
| Qg | 18 nC - Low gate drive energy reduces controller IC loading and enables efficient 65–130 kHz operation. |
| EAS | 84 mJ - Fully rated for unclamped inductive switching stress in flyback transformer reset. |
| TJ max | 150 °C - Supports sealed or thermally constrained enclosures without forced cooling. |
| dV/dt | 3.0 V/ns - Immune to parasitic turn-on in high-noise SMPS layouts with minimal gate resistor need. |
| ID cont. | 2.2 A @ TC = 25 °C - Matches typical peak currents in 30–45 W flyback designs with margin. |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain pad for thermal and electrical connection; 3-pin configuration (G-D-S), 10.67 mm × 9.65 mm footprint, 4.83 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Gate (G) | Control terminal | Receives 10 V logic-level drive; 3.0 nC Qgs ensures fast Miller plateau exit and low switching loss. |
| Drain (D) | High-voltage output node | Connected to transformer primary and bulk capacitor; ties directly to thermal pad for heat sinking and low-inductance return path. |
| Source (S) | Reference node / current sense point | Provides return path for load current and gate drive loop; low-inductance layout critical for dv/dt stability. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP6NK60ZFP | 600 V, 5.5 Ω RDS(on), 16 nC Qg, TO-220FP package | Higher RDS(on) increases conduction loss; through-hole mounting requires manual soldering or wave process. | Select when legacy board layout uses TO-220FP footprints and thermal mass compensates for higher on-resistance. |
| FQP6N60C | 600 V, 5.0 Ω RDS(on), 22 nC Qg, TO-220 package | Higher gate charge slows switching; no avalanche rating specified-requires external clamping for flyback reset. | Choose only for non-avalanche-critical applications where cost is prioritized over reliability margin and thermal performance. |
Compared with STP6NK60ZFP and FQP6N60C, IRFBC20STRLPBF delivers lower conduction loss, surface-mount compatibility, and guaranteed avalanche ruggedness-making it optimal for new designs targeting compact, high-reliability AC-DC conversion.

FAQ
What is the maximum continuous drain current for IRFBC20STRLPBF at 100 °C case temperature?
The maximum continuous drain current for IRFBC20STRLPBF is 1.4 A at TC = 100 °C, per the Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under sustained high-temperature operation and must be verified against actual PCB copper area and airflow in the end application. IRFBC20STRLPBF maintains full 2.2 A rating only at TC = 25 °C.
Does IRFBC20STRLPBF have a fully rated avalanche capability, and what does that mean for circuit design?
Yes, IRFBC20STRLPBF is fully avalanche rated with 84 mJ single-pulse EAS and 5.0 mJ repetitive EAR. This means the device can safely absorb inductive energy from transformer leakage without external snubbers in flyback converters, eliminating design complexity and component count. IRFBC20STRLPBF's avalanche specification is tested per JEDEC standards and applies across its full temperature range.
What is the gate threshold voltage range for IRFBC20STRLPBF, and how does it affect drive requirements?
The gate threshold voltage (VGS(th)) for IRFBC20STRLPBF is specified from 2.0 V to 4.0 V at ID = 250 μA. This range confirms standard-level-not logic-level-drive compatibility, requiring ≥10 V gate-source voltage for full enhancement. IRFBC20STRLPBF will not reliably turn on with 5 V controllers; use of a dedicated gate driver or bootstrap circuit is recommended for robust switching.
Can IRFBC20STRLPBF be used in place of IRFBC20L, and what are the key mechanical differences?
No, IRFBC20STRLPBF and IRFBC20L are not mechanically interchangeable: IRFBC20STRLPBF uses the surface-mount D2PAK (TO-263) package, while IRFBC20L uses the low-profile through-hole I2PAK (TO-262). The D2PAK has an exposed drain pad for thermal attachment, whereas the I2PAK has a bent leadform for vertical mounting. IRFBC20STRLPBF requires reflow-compatible PCB pads per Vishay AN826; IRFBC20L needs wave-solder compatible holes.
What is the typical body diode reverse recovery time for IRFBC20STRLPBF, and why does it matter in flyback designs?
The typical body diode reverse recovery time (trr) for IRFBC20STRLPBF is 290 ns at TJ = 25 °C, with a maximum of 580 ns. In flyback converters, short trr minimizes reverse recovery current spikes during primary switch turn-on, reducing EMI and preventing cross-conduction losses. IRFBC20STRLPBF's low Qrr (0.67 μC) further suppresses associated switching loss, improving light-load efficiency.
