In various high-voltage, high-frequency application scenarios such as switch-mode power supplies, industrial inverters, LED lighting drivers, welding machines, and UPS systems, Littelfuse IXYS's IXTP4N70X2M, with its advanced technology and robust design, has been a preferred choice for engineers worldwide. However, in the post-pandemic era, global supply chain disruptions and international trade frictions have exposed pain points for this imported component: unstable lead times, procurement costs affected by exchange rate fluctuations, and slow technical support responses. These issues severely constrain production schedules and cost control for downstream companies. Given this industry demand, domestic substitution has transitioned from an "option" to a "necessity," becoming a critical path for enterprises to ensure supply chain security, reduce costs, and enhance competitiveness.
VBsemi, with years of deep cultivation in the power semiconductor field, launches the VBMB17R05S N-channel power MOSFET based on its independent R&D capabilities. This product precisely targets the IXTP4N70X2M, offering core advantages of parameter upgrades, technological parity, and full package compatibility. It can serve as a direct replacement without any modifications to the original circuit, providing a more stable, cost-effective, and locally attuned high-quality solution for various high-voltage electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the IXTP4N70X2M, the VBMB17R05S achieves significant improvements in key electrical parameters, offering robust performance guarantees for high-voltage applications:
Firstly, the drain-source voltage remains at 700V, matching the original model's rating, ensuring reliable operation in high-voltage environments. Secondly, the continuous drain current is increased to 5A, a 25% enhancement over the original model's 4A, providing higher current-carrying capability for more demanding power applications. This allows for adaptation to higher power-level designs or improved system stability at the same power level.
Thirdly, the on-state resistance is optimized to 1100mΩ (@10V gate drive), offering a balanced performance for conduction and switching losses in diverse circuit conditions. Additionally, the VBMB17R05S supports a ±30V gate-source voltage, offering stronger gate ESD and noise immunity, effectively preventing unintended turn-on in complex electromagnetic environments. The 3.5V gate threshold voltage design balances driving convenience and switching reliability, perfectly matching mainstream driver ICs without requiring additional adjustments to the drive circuit.
Enhanced with Advanced SJ_Multi-EPI Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the IXTP4N70X2M lies in its high voltage and efficient performance. The VBMB17R05S employs the industry-leading SJ_Multi-EPI (Super Junction Multi-Epitaxial) technology, building upon excellent switching characteristics while optimizing device reliability across multiple dimensions. The device undergoes rigorous testing and screening before leaving the factory, exhibiting excellent avalanche energy performance. It can handle energy surges during high-voltage turn-off, reducing the risk of device damage. Through optimized intrinsic capacitance design, it reduces charge/discharge losses during switching and enhances dv/dt tolerance, perfectly matching the application scenarios of the IXTP4N70X2M. Even under harsh conditions like high-frequency switching, it maintains stable operation. Furthermore, the VBMB17R05S features a wide operating temperature range, capable of adapting to various complex working conditions. Having passed long-term reliability verification, its failure rate is far below the industry average, providing solid assurance for long-term equipment operation—especially suitable for critical fields like industrial control, medical equipment, and emergency power supplies.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
For downstream enterprises, a core concern regarding domestic substitution is the R&D investment and time costs. The VBMB17R05S fundamentally addresses this pain point through its package design. The device uses a TO-220F package, which is fully compatible with the IXTP4N70X2M's package in terms of pinout, pin spacing, and dimensions. Engineers need not make any modifications to the original PCB layout or thermal design, achieving "plug-and-play" replacement. This high compatibility reduces substitution verification time—sample validation can typically be completed within 1-2 days. It avoids increased production costs from PCB revisions and ensures the original product's structural dimensions remain unchanged, eliminating re-certification needs. This effectively shortens the supply chain cycle, helping enterprises quickly achieve substitution and seize market opportunities.
