Product details
Overview
IRF624SPBF from Vishay Siliconix is a 250 V, 4.4 A N-channel surface-mount power MOSFET in D2PAK (TO-263) package, featuring 1.1 Ω RDS(on) at VGS = 10 V, 14 nC total gate charge, and repetitive avalanche rating-designed for high-voltage DC-DC converters, motor control stages, and industrial power switching where ruggedness and fast switching are critical.
For engineers reviewing the IRF624SPBF datasheet, IRF624SPBF pinout, IRF624SPBF application, or IRF624SPBF equivalent, key selection considerations include its 250 V drain-source breakdown voltage, 1.1 Ω on-resistance at 10 V gate drive, 4.4 A continuous drain current at TC = 25 °C, and D2PAK thermal performance enabling up to 50 W dissipation with heatsink mounting.
Technical Context
This device belongs to Vishay's third-generation power MOSFET family optimized for high-voltage switching with low conduction loss and robust avalanche capability. Its dynamic dv/dt rating of 4.8 V/ns and body diode reverse recovery time of 200–400 ns support reliable operation in inductive load circuits.
The IRF624SPBF uses planar silicon technology with HEX-4 die size in D2PAK, delivering lowest possible RDS(on) among surface-mount packages at this voltage class. Its gate threshold voltage range (2.0–4.0 V) ensures compatibility with standard 10 V logic-level drivers while maintaining noise immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 250 V - Supports input rails up to 200 V DC in offline or industrial SMPS without derating. |
| RDS(on) @ VGS = 10 V | 1.1 Ω - Enables ≤5 W conduction loss at 4.4 A, suitable for thermally constrained PCB-mount designs. |
| Qg | 14 nC - Determines gate drive power requirement; compatible with low-current 10 V drivers (e.g., TC4427). |
| ID (continuous, TC = 25 °C) | 4.4 A - Sustains full-load current in compact 1" × 1" FR-4 PCB layouts with 3.1 W natural convection limit. |
| EAS | 100 mJ - Withstands unclamped inductive energy spikes in relay/motor driver fault conditions without failure. |
| TJ range | −55 to +150 °C - Qualified for extended industrial temperature operation including motor drive enclosures. |
| Body diode VSD | 1.8 V @ IS = 4.4 A - Limits freewheeling loss during synchronous rectification or flyback catch phases. |
Pinout & Package
D2PAK (TO-263) package: surface-mount power package with exposed drain pad for thermal conduction; 3-pin configuration (G, D, S); 9.65 mm × 10.67 mm footprint; 14.61 mm height; RoHS-compliant lead-free termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Drain (D) | High-side power output | Connected to exposed copper thermal pad; carries full load current and must be routed over large copper pour for heat dissipation. |
| Source (S) | Reference node / return path | Provides ground reference for gate drive; internal source inductance (7.5 nH) affects high-speed switching ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Repetitive avalanche rated | Withstands 4.4 A repetitive avalanche current and 5.0 mJ energy per pulse-enables robust operation in inductive switching without external snubbers. |
| Dynamic dv/dt rating | 4.8 V/ns - Prevents false turn-on during high-slew-rate voltage transients in half-bridge or LLC resonant topologies. |
| Fast switching | 7.0 ns turn-on delay + 13 ns rise time - Reduces switching losses below 200 kHz, supporting efficient medium-frequency SMPS. |
| Low gate charge | 14 nC total with 2.7 nC gate-source component - Minimizes driver power consumption and simplifies gate resistor selection. |
| Surface-mount packaging | D2PAK footprint supports automated assembly and delivers 2.0 W power dissipation on standard FR-4 PCB without heatsink. |

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 |
|---|---|---|---|
| STP25NM50FP | 500 V VDS, 25 A ID, 0.22 Ω RDS(on), TO-220FP package | Higher voltage/current rating but through-hole; requires PCB cutout and heatsink mounting | Choose when higher power density and forced-air cooling are available; not drop-in for D2PAK layout. |
| SiHF624S-GE3 | Identical electrical specs; same D2PAK package; halogen-free, lead-free construction per JEDEC J-STD-020 | No functional difference; qualified for automotive-grade reflow profiles | Preferred for RoHS/halogen-free compliance programs; identical pinout and thermal behavior to IRF624SPBF. |
Compared with STP25NM50FP and SiHF624S-GE3, the IRF624SPBF offers optimal balance of 250 V rating, D2PAK surface-mount compatibility, and 1.1 Ω on-resistance for space-constrained industrial power stages-where SiHF624S-GE3 serves as a direct material-compliance alternative, while STP25NM50FP addresses higher-power through-hole needs.

FAQ
What is the maximum continuous drain current for IRF624SPBF at 100 °C case temperature?
The IRF624SPBF supports 2.8 A continuous drain current at TC = 100 °C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal resistance limitations in surface-mount configurations; designers must ensure adequate copper area and airflow to maintain case temperature within this limit during sustained operation. The IRF624SPBF datasheet confirms this value under standard test conditions with PCB mount.
Does IRF624SPBF have a built-in body diode, and what are its key parameters?
Yes, the IRF624SPBF integrates a monolithic body diode with 4.4 A continuous forward current rating, 1.8 V forward voltage at 4.4 A and 25 °C, and reverse recovery time of 200–400 ns. These values are measured under standardized conditions (TJ = 25 °C, IF = 4.4 A, di/dt = 100 A/μs) and directly impact performance in freewheeling and synchronous rectification applications. The IRF624SPBF body diode characteristics are fully documented in the "Drain-Source Body Diode Characteristics" section of its datasheet.
Can IRF624SPBF be used with 5 V logic-level gate drive?
No-the IRF624SPBF has a gate threshold voltage range of 2.0–4.0 V and is not a logic-level MOSFET; it requires 10 V gate drive to achieve its specified 1.1 Ω RDS(on). At 5 V, RDS(on) increases significantly (not characterized in datasheet), leading to excessive conduction loss. For 5 V drive, consider dedicated logic-level alternatives. The IRF624SPBF gate drive specification is explicitly defined for VGS = 10 V in all key parameter tables.
What is the thermal resistance from junction to ambient for IRF624SPBF in standard PCB mount?
The maximum junction-to-ambient thermal resistance (RthJA) for IRF624SPBF in PCB mount configuration is 40 °C/W, measured on a 1" × 1" FR-4 board per JEDEC standards. This value assumes no external heatsink and defines the worst-case temperature rise under 3.1 W power dissipation. The IRF624SPBF thermal performance is validated in the "Thermal Resistance Ratings" table of its official datasheet.
Is IRF624SPBF RoHS-compliant and halogen-free?
The IRF624SPBF is RoHS-compliant (lead-free) but not halogen-free; its ordering code "PbF" indicates lead-free termination only. For halogen-free compliance, use SiHF624S-GE3, which is functionally identical and explicitly certified halogen-free per JEDEC J-STD-020. The IRF624SPBF material status is confirmed in the "Ordering Information" and "Material categorization" sections of Vishay document 91030.
