Product details
Overview
IRF620SPBF from Vishay Siliconix is a 200 V, 5.2 A N-channel enhancement-mode power MOSFET in D2PAK (TO-263) package, featuring 0.80 Ω RDS(on) at VGS = 10 V, 14 nC total gate charge, and repetitive avalanche rating-designed for high-efficiency DC-DC converters, motor control stages, and industrial power switching.
For engineers reviewing the IRF620SPBF datasheet, IRF620SPBF pinout, IRF620SPBF application, or IRF620SPBF equivalent, key selection criteria include its 200 V VDS, 5.2 A continuous drain current at TC = 25 °C, 2.5 °C/W junction-to-case thermal resistance, fast 7.2 ns turn-on delay, and surface-mount D2PAK package suitability for high-current PCB-mounted power stages.
Technical Context
This third-generation Vishay power MOSFET uses planar silicon technology optimized for ruggedness and fast switching in hard-switched topologies. Its dynamic dv/dt rating of 5.0 V/ns and unclamped inductive switching capability support reliable operation in flyback, forward, and half-bridge configurations with minimal snubbing.
The device integrates a low-Qgd/Qg ratio (7.9/14 nC), enabling efficient gate drive with reduced Miller-induced shoot-through risk. Its body diode exhibits 150–300 ns reverse recovery time and 0.91–1.8 μC Qrr, making it suitable for synchronous rectification and freewheeling where controlled diode conduction is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 200 V - Maximum blocking voltage for primary-side switching in 110–240 VAC offline supplies and 48 V industrial bus systems. |
| RDS(on) @ VGS = 10 V | 0.80 Ω - Enables ≤2.0 W conduction loss at 5.2 A, supporting thermally constrained surface-mount power stages. |
| ID (continuous, TC = 25 °C) | 5.2 A - Sustains full-load current in compact 1"² FR-4 PCB mount without heatsink under typical ambient conditions. |
| Qg (total) | 14 nC - Determines gate driver current requirement (~1.4 A peak for 10 ns rise time), critical for PWM efficiency at 100–500 kHz. |
| EAS (single-pulse) | 110 mJ - Supports energy absorption during unclamped inductive turn-off, reducing need for external clamping in relay drivers and solenoid controls. |
| RthJC | 2.5 °C/W - Enables direct thermal coupling to copper pour or heatsink, delivering up to 50 W dissipation when case-mounted. |
| dv/dt rating | 5.0 V/ns - Ensures immunity to false turn-on in high-noise environments such as motor drives and SMPS with fast edge rates. |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed drain tab for thermal and electrical connection; 3-terminal configuration (G, D, S); 14.61–15.88 mm height; 8.38–9.65 mm width; 9.65–10.67 mm length; 1.78–2.79 mm lead thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP20NM20 | 200 V VDS, 20 A ID, 0.12 Ω RDS(on), TO-220 package | Higher current rating but larger through-hole footprint; lacks D2PAK thermal performance on PCB | Preferred for higher-current designs where board space permits through-hole mounting and heatsinking. |
| IXTP50N20P | 200 V VDS, 50 A ID, 0.045 Ω RDS(on), TO-220 package | Lower RDS(on) and higher ID, but significantly higher Qg (72 nC) and no surface-mount option | Selected when ultra-low conduction loss dominates over switching loss and layout flexibility allows TO-220 placement. |

FAQ
What is the maximum continuous drain current for IRF620SPBF at 100 °C case temperature?
The IRF620SPBF supports 3.3 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limitations of the D2PAK package under sustained high-temperature operation. Designers must verify PCB copper area and airflow to maintain safe junction temperatures below 150 °C. The IRF620SPBF datasheet confirms this value with linear derating factor of 0.40 W/°C above 25 °C case temperature.
Does IRF620SPBF have a built-in body diode, and what are its key parameters?
Yes, the IRF620SPBF integrates a parasitic body diode inherent to its vertical N-channel MOSFET structure. Key parameters include 5.2 A continuous source-drain current, 18 A pulsed rating, 1.8 V forward voltage at 5.2 A and 25 °C, and 150–300 ns reverse recovery time with 0.91–1.8 μC Qrr. These values are measured under standardized conditions per the IRF620SPBF datasheet and enable use in freewheeling and synchronous rectification roles.
What is the gate threshold voltage range for IRF620SPBF, and how does it affect drive requirements?
The IRF620SPBF has a gate-source threshold voltage (VGS(th)) range of 2.0 V to 4.0 V at TJ = 25 °C and ID = 250 μA. This standard-level threshold requires ≥10 V gate drive for full enhancement and low RDS(on), distinguishing it from logic-level MOSFETs. The IRF620SPBF is not compatible with 3.3 V or 5 V microcontroller outputs without level-shifting or gate driver amplification.
Can IRF620SPBF be paralleled with identical units, and what design considerations apply?
Yes, the IRF620SPBF is designed for ease of paralleling due to its positive temperature coefficient of RDS(on), which promotes current sharing across multiple devices. Designers must ensure matched gate drive impedance, symmetrical PCB layout, and shared thermal mass to avoid imbalance. The IRF620SPBF datasheet explicitly lists "Ease of paralleling" as a feature, validated by thermal and electrical characterization across production lots.
What is the thermal resistance from junction to ambient for IRF620SPBF in standard PCB mount?
When mounted on a 1" square FR-4 PCB, the IRF620SPBF exhibits a maximum junction-to-ambient thermal resistance (RthJA) of 40 °C/W. This value assumes standard JEDEC test conditions and is significantly lower than the 62 °C/W rating for still-air ambient. The IRF620SPBF achieves this via its D2PAK package's exposed drain tab, which must be fully soldered to a thermal pad for optimal performance.
