Product details
Overview
BSF024N03LT3G from ON Semiconductor is a 30 V, 106 A N-channel Power MOSFET in CanPAKTM MG-WDSON-2 package, optimized for high-frequency DC/DC converters with RDS(on) = 2.4 mΩ @ VGS = 10 V, Qg = 53 nC, and double-sided cooling capability. It serves as a primary synchronous rectifier or high-side switch in server VRMs and POL converters.
For engineers reviewing the BSF024N03LT3G datasheet, BSF024N03LT3G pinout, BSF024N03LT3G application, or BSF024N03LT3G equivalent, key selection criteria include its 2.4 mΩ on-resistance at 10 V gate drive, 53 nC total gate charge, 100% avalanche-tested ruggedness, and compatibility with ST's DirectFET® footprint for drop-in layout reuse in space-constrained power stages.
Technical Context
This MOSFET employs trench-gate OptiMOSTM3 technology to minimize conduction and switching losses simultaneously. Its low RDS(on) × Qg figure-of-merit (FOM) and reduced parasitic inductance support >1 MHz operation in multiphase buck converters.
The device features a thermally enhanced CanPAKTM package with exposed drain on both top and bottom surfaces, enabling dual thermal paths. Gate threshold voltage is tightly specified (1–2.2 V), and it is fully characterized for synchronous FET operation with Qg(sync) = 22 nC at 4.5 V drive.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 30 V - Maximum blocking voltage for 12 V input bus applications with margin |
| RDS(on) max | 2.4 mΩ @ VGS = 10 V - Enables <1.5 W conduction loss at 60 A continuous current |
| ID cont | 106 A @ TC = 25 °C - Supports high-current single-phase or parallel-phase POL designs |
| Qg | 53 nC @ VDD = 15 V, ID = 30 A - Determines gate driver strength requirement for <30 ns turn-on |

Pinout & Package
The BSF024N03LT3G uses the MG-WDSON-2 CanPAKTM package (ST outline 0703), a surface-mount, leadless, double-sided cooling module with drain-connected top and bottom metal pads and a single gate-source terminal on the side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Top Pad) | Power output node / Heat sink interface | Electrically and thermally connected to internal die drain; used for top-side cooling |
| Drain (Bottom Pad) | Main current path / PCB thermal plane | Primary current return path and main thermal interface to PCB copper area |
| Gate | Switching control input | Low-impedance gate terminal with RG = 0.5 Ω typical; requires Kelvin connection for high-di/dt stability |
| Source | Reference node for gate drive and current sensing | Internally tied to substrate; must be routed with minimal inductance for accurate VGS control |
Key Features
| Feature | Design Value |
|---|---|
| Optimized for >1 MHz DC/DC conversion | Low Ciss/Coss ratio and 5.7 ns td(on) enable stable operation in advanced POL regulators |
| Double-sided cooling architecture | Simultaneous top/bottom thermal interfaces reduce junction-to-ambient ΔT by up to 40% vs. standard SO-8 |
| 100% avalanche tested | Guarantees minimum 125 mJ single-pulse EAS - critical for unclamped inductive switching reliability |
| Qg × RDS(on) FOM = 127 Ω·nC | Industry-leading efficiency trade-off metric for high-frequency, high-current power stages |
| DirectFET®-compatible footprint | Enables direct PCB layout reuse with ST's STD80N3LH5 and similar ST/IR devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-frequency power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STD80N3LH5 | RDS(on) = 2.8 mΩ @ 10 V; Qg = 62 nC; same CanPAKTM footprint | Slightly higher conduction loss; less optimized for >1 MHz switching | Preferred where layout reuse is mandatory and 10–15% higher loss is acceptable |
| IRF6642 | RDS(on) = 2.3 mΩ @ 10 V; Qg = 42 nC; DirectFET® MX package | Lower gate charge but no top-side cooling; different thermal mounting interface | Chosen when gate drive efficiency dominates over thermal density constraints |
Compared with STD80N3LH5 and IRF6642, the BSF024N03LT3G uniquely balances ultra-low RDS(on), industry-leading FOM, and dual thermal interface - making it optimal for thermally dense, high-frequency VRMs where both electrical and thermal performance are co-constrained.

FAQ
What is the maximum recommended gate drive voltage for BSF024N03LT3G?
The absolute maximum gate-source voltage is ±20 V, but the device is characterized and optimized for 10 V drive in high-current applications. Using 4.5 V gate drive yields Qg(sync) = 22 nC and supports synchronous rectifier operation with logic-level controllers. Exceeding 12 V does not significantly reduce RDS(on) and increases gate oxide stress risk.
Does BSF024N03LT3G require a gate resistor for stability?
Yes - a 1.6 Ω external gate resistor is used in the datasheet's Qg test condition (VDD = 15 V, ID = 30 A) to dampen ringing and limit peak gate current. For 1 MHz+ operation, a 1–2 Ω resistor combined with Kelvin source routing is recommended to suppress parasitic oscillation caused by low Ciss/Coss and high di/dt.
Can BSF024N03LT3G be mounted with thermal interface material on both sides?
Yes - the CanPAKTM package is explicitly designed for double-sided cooling. The top drain pad accepts thermal pads or phase-change materials, while the bottom pad connects directly to a 6 cm² copper area per JEDEC J-STD-20. Both interfaces must be electrically isolated from other circuit nodes but may share the same thermal ground plane.
Is the body diode suitable for reverse recovery in synchronous rectification?
The body diode has Qrr = 28 nC at dI/dt = 400 A/µs and VR = 15 V, confirming soft recovery behavior. This enables zero-voltage switching (ZVS) transitions in synchronous buck topologies without external Schottky assist, reducing EMI and improving light-load efficiency compared to standard MOSFETs with hard-recovery diodes.
