In high-frequency switching and synchronous rectification applications such as server & telecom power supplies, high-density DC-DC converters, and motor drives, Infineon's IPB024N10N5, renowned for its excellent figure of merit (FOM: gate charge x RDS(on)), ultra-low on-resistance, and 100% avalanche testing, has been a preferred choice for design engineers. However, facing global supply chain uncertainties and procurement challenges, the need for a reliable, high-performance domestic alternative has become increasingly critical. Addressing this demand, VBsemi introduces the VBGL7101 N-channel MOSFET, a pin-to-pin replacement for the IPB024N10N5, offering superior electrical parameters, advanced SGT (Shielded Gate Trench) technology, and full package compatibility, thereby providing a more robust and efficient solution for demanding power designs.
Superior Parameters for Enhanced Performance and Efficiency
Engineered as a direct upgrade to the IPB024N10N5, the VBGL7101 demonstrates significant improvements in key specifications, ensuring higher performance margins and reliability:
- Higher Current Handling: The continuous drain current (Id) is rated at 250A, substantially exceeding the 217A of the IPB024N10N5. This 15% increase in current capability supports higher power density and improves operational stability in high-current applications.
- Lower Conduction Losses: With an on-state resistance (RDS(on)) of just 1.2mΩ (at Vgs=10V), the VBGL7101 outperforms the IPB024N10N5's 2.4mΩ. This 50% reduction in RDS(on) significantly decreases conduction losses, enhances overall system efficiency, and reduces thermal dissipation requirements.
- Robust Voltage Ratings: The device maintains a drain-source voltage (Vdss) of 100V, matching the original part, while supporting a gate-source voltage (Vgs) of ±20V and a standard threshold voltage (Vth) of 3V. This ensures strong noise immunity and reliable switching, compatible with mainstream driver ICs without circuit modifications.
Advanced SGT Technology for Optimal Switching Performance
The IPB024N10N5 is valued for its excellent FOM. The VBGL7101 leverages VBsemi's proprietary SGT (Shielded Gate Trench) MOSFET technology, which achieves an exceptional balance between low gate charge (Qg) and low RDS(on). This results in superior switching performance, significantly reducing switching losses—especially critical in high-frequency applications. The technology also enhances dv/dt robustness and device reliability. Furthermore, the VBGL7101 undergoes 100% avalanche energy testing, ensuring ruggedness against inductive switching surges. Its wide operating temperature range and compliance with RoHS and halogen-free standards (per IEC61249-2-21) make it suitable for industrial, automotive, and consumer applications requiring high reliability.
Seamless Drop-In Replacement with TO263-7L Package
To facilitate a swift and risk-free transition, the VBGL7101 is offered in a TO263-7L (D²PAK-7L) package, which is mechanically and electrically identical to the IPB024N10N5's package. This complete pin-to-pin and footprint compatibility allows for direct "drop-in" replacement without any changes to the existing PCB layout or thermal management design. This eliminates redesign costs, accelerates verification cycles (typically within 1-2 days for sample testing), and streamlines the qualification process, enabling rapid product iteration and time-to-market.
Guaranteed Supply Chain Stability and Local Technical Support
Unlike imported components susceptible to long lead times and logistic disruptions, VBsemi's domestic manufacturing capabilities ensure a stable and responsive supply for the VBGL7101. Standard lead times are reliably short, with expedited support available for urgent needs. Moreover, VBsemi provides comprehensive local technical support, including detailed application notes, substitution validation reports, and dedicated engineering assistance. This ensures prompt resolution of any design integration challenges, effectively overcoming the slow support response often associated with overseas suppliers.
From high-efficiency switched-mode power supplies and synchronous rectification stages to motor drives and automotive systems, the VBGL7101 stands out as the premier domestic alternative to the IPB024N10N5. With its higher current rating, significantly lower RDS(on), advanced SGT technology, and seamless package compatibility, it offers a compelling upgrade path—enhancing performance, securing the supply chain, and reducing total cost without incurring redesign risks. Choosing the VBGL7101 is a strategic decision for achieving greater product competitiveness and reliability.
