Product details
Overview
IRFD020PBF from Vishay Siliconix is a 50 V, 2.4 A N-channel power MOSFET in HVMDIP (High Voltage Mini Dual-In-Line) package, featuring 0.10 Ω RDS(on) at VGS = 10 V, 24 nC total gate charge, and fast switching with 13 ns turn-on delay. It serves as a low-side switch in DC-DC converters, printer motor drivers, and telecom power supplies where automatic PCB insertion and thermal stability are required.
For engineers reviewing the IRFD020PBF datasheet, IRFD020PBF pinout, IRFD020PBF application, or IRFD020PBF equivalent, key selection criteria include its 50 V VDS, 0.10 Ω on-resistance at 10 V drive, 120 °C/W RthJA, HVMDIP leadform compatibility with wave soldering, and body diode recovery time of 130 ns (typical).
Technical Context
The IRFD020PBF uses Vishay's HVMDIP process to achieve low RDS(on) (0.080 Ω typ.) while maintaining high transconductance (7.3 S typ.) and rugged avalanche capability (2.2 A unclamped inductive current). Its geometry supports stable operation from −55 °C to +150 °C junction temperature.
Designed for high-volume automated assembly, the device integrates a monolithic N-channel enhancement-mode structure with an integral source-drain body diode (VSD = 1.4 V at 2.4 A), optimized for clamped inductive switching (19 A ILM) and fast turn-off (24 ns td(off)).

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 |
|---|---|---|---|
| STP2NK50Z | 500 V VDS, 1.7 A ID, 4.5 Ω RDS(on) - Higher voltage, lower current, much higher on-resistance | Designed for offline SMPS primary side; unsuitable for 24–48 V low-loss switching | Select only if 500 V blocking is required; not a functional substitute for IRFD020PBF in low-voltage, high-current roles |
| IRF520NPBF | 100 V VDS, 9.2 A ID, 0.27 Ω RDS(on) - Higher voltage rating but 2.7× higher on-resistance at same current | General-purpose TO-220 switch; lacks HVMDIP automation features and dual-drain layout | Use when higher voltage margin or TO-220 mounting is needed; expect ~2.7× higher conduction loss at 2.4 A |
Compared with STP2NK50Z and IRF520NPBF, the IRFD020PBF delivers optimal balance of low on-resistance (0.10 Ω), compact HVMDIP packaging, and 2.4 A continuous current in 48 V-class systems-making it uniquely suited for space-constrained, high-volume automated power switching where thermal and drive efficiency are critical.

FAQ
What is the maximum continuous drain current for IRFD020PBF at 100 °C case temperature?
The IRFD020PBF supports 1.5 A continuous drain current at TC = 100 °C, per its absolute maximum ratings table. This derating reflects thermal limitations of the HVMDIP package without heatsinking. At 25 °C case temperature, the rating rises to 2.4 A. Designers must verify junction temperature using RthJA = 120 °C/W and actual power dissipation to ensure operation remains within −55 °C to +150 °C TJ limits. The IRFD020PBF datasheet specifies linear derating beyond 25 °C.
Does IRFD020PBF have a built-in body diode, and what are its key parameters?
Yes, the IRFD020PBF integrates a monolithic source-drain body diode with VSD = 1.4 V (max) at IS = 2.4 A and TC = 25 °C. Its reverse recovery time is 130 ns (typical) at TJ = 25 °C, IF = 15 A, and dI/dt = 100 A/μs, with Qrr = 0.34 μC (typical). These values make the IRFD020PBF suitable for freewheeling and synchronous rectification in non-isolated DC-DC converters where moderate recovery performance is acceptable.
Can IRFD020PBF be driven directly by a 3.3 V microcontroller GPIO?
No-IRFD020PBF has a gate threshold voltage range of 2.0–4.0 V, and its RDS(on) is specified at VGS = 10 V. A 3.3 V drive will result in incomplete turn-on and significantly elevated RDS(on), risking thermal failure at rated current. The IRFD020PBF requires a dedicated gate driver or level-shifting circuit to deliver ≥10 V to ensure full enhancement. Logic-level MOSFETs like IRLML6344 are better suited for direct 3.3 V GPIO drive.
What is the significance of the dual-drain (Pins 2 and 4) configuration in IRFD020PBF?
The dual-drain configuration in the IRFD020PBF reduces effective package inductance and improves current distribution in high-di/dt applications. Pins 2 and 4 are internally connected to the same drain region, allowing either single-point or split routing to minimize loop area. This layout lowers electromagnetic interference and enhances reliability in motor drive and converter switching nodes. It also facilitates mechanical stability during automated insertion and wave soldering-key advantages of the HVMDIP package used in the IRFD020PBF.
Is IRFD020PBF RoHS-compliant and halogen-free?
Yes, IRFD020PBF is lead (Pb)-free and RoHS-compliant, as indicated by the "PbF" suffix in its ordering code and confirmed in Vishay's material declaration (doc# 99912). It meets JEDEC JS709B and IEC 61249-2-21 requirements for halogen-free materials (<900 ppm Cl, <900 ppm Br, <1500 ppm total halogens). Full compliance documentation is available at www.vishay.com/doc?99912 for the IRFD020PBF.
