In medium-voltage, high-current application domains such as server/telecom power supplies, motor drives, Class-D audio amplifiers, and synchronous rectification circuits, Infineon's IPP089N15NM6AKSA1, renowned for its extremely low on-resistance, excellent thermal performance, and 100% avalanche testing, has been a preferred choice for design engineers. However, amidst global supply chain uncertainties and escalating procurement complexities, reliance on such imported components often leads to challenges including extended lead times, cost volatility, and delayed technical support. This situation compels the industry to seek reliable, high-performance domestic alternatives to secure production continuity and enhance cost efficiency.
Responding to this critical demand, VBsemi introduces the VBGM11505 N-channel power MOSFET, a superior domestic counterpart engineered to directly replace the IPP089N15NM6AKSA1. This product delivers significant parameter enhancements, leverages advanced SGT (Shielded Gate Trench) technology, and ensures full package compatibility, enabling a seamless, drop-in replacement that offers higher performance, greater stability, and optimized cost-effectiveness for demanding medium-voltage systems.
Substantial Parameter Advancements, Delivering Enhanced Power Handling and Efficiency.
Designed as a direct upgrade to the IPP089N15NM6AKSA1, the VBGM11505 achieves remarkable improvements across all key electrical specifications, providing substantial performance headroom for more robust designs:
- Drain Current (Id): Rated at 140A, a dramatic 59% increase over the original 88A. This vastly superior current-carrying capacity effortlessly supports higher power density requirements and enhances system overload tolerance.
- On-State Resistance (RDS(on)): Reduced to an ultra-low 5.8mΩ (at Vgs=10V), significantly lower than the 7.1mΩ (at Vgs=15V) of the IPP089N15NM6AKSA1. This 18% reduction in conduction loss translates directly into higher efficiency, lower operating temperatures, and reduced thermal management overhead.
- Voltage Ratings: Maintains a 150V drain-source voltage (Vdss) match, perfectly suited for standard 48V-100V bus applications, while offering a ±20V gate-source voltage range for robust gate protection.
Furthermore, the VBGM11505 features a standard 3.5V gate threshold voltage, ensuring easy drive compatibility with mainstream controller ICs without necessitating circuit modifications.
Advanced SGT Technology, Ensuring Superior Switching and Thermal Reliability.
While the IPP089N15NM6AKSA1 excels with its low RDS(on), the VBGM11505 employs VBsemi's proprietary SGT (Shielded Gate Trench) MOSFET technology. This advanced architecture not only achieves the critically low on-resistance but also optimizes the device's switching characteristics by reducing gate charge (Qg) and intrinsic capacitances. The result is faster switching speeds, lower switching losses, and improved efficiency in high-frequency operation. The optimized cell design also contributes to excellent thermal resistance, facilitating more effective heat dissipation. The device undergoes 100% avalanche energy testing, guaranteeing ruggedness and reliability against inductive switching spikes. With an operating junction temperature range up to 150°C and validated through rigorous reliability testing, the VBGM11505 ensures stable, long-term operation in challenging environments, making it ideal for mission-critical applications.
Full Package and Footprint Compatibility, Enabling Zero-Risk Direct Replacement.
The VBGM11505 eliminates all barriers to substitution through its complete mechanical compatibility. It is offered in the industry-standard TO-220 package, which is pin-for-pin, footprint-for-footprint identical to the IPP089N15NM6AKSA1. Engineers can directly replace the existing component on the PCB without any layout changes, thermal redesign, or mechanical adjustments. This "plug-and-play" approach slashes qualification time and cost, allowing production lines to switch to the domestic alternative rapidly and seamlessly, with verification often completed within days.
Localized Supply Chain and Expert Support, Providing Dual Assurance.
VBsemi's domestic manufacturing foundation guarantees a stable, responsive supply for the VBGM11505, with lead times typically within weeks, starkly contrasting the unpredictability of international logistics. This shields customers from geopolitical, tariff, and allocation risks. Complementing this supply security is VBsemi's dedicated local technical support team, which provides prompt, personalized assistance—from detailed substitution guides and application notes to rapid on-site or remote troubleshooting—ensuring a smooth and successful transition.
From high-efficiency server PSUs and robust motor controllers to high-fidelity audio amplifiers and power conversion stages, the VBGM11505 stands as the optimal domestic alternative to the IPP089N15NM6AKSA1. It combines the core advantages of higher performance, inherent reliability, perfect compatibility, and secured supply. Choosing the VBGM11505 is a strategic upgrade that enhances product competitiveness and supply chain resilience without incurring redesign risks or compromises.
