VBL1615: The Perfect Domestic Alternative to RENESAS IDT 2SK3434-Z-AZ, A More Reliable Choice for High-Current Applications
In various high-current, low-voltage application scenarios such as motor drives, power tools, automotive systems, and industrial controllers, RENESAS IDT's 2SK3434-Z-AZ, with its low on-resistance and high current capability, has been a popular choice for engineers worldwide. However, in the post-pandemic era with global supply chain disruptions and trade frictions, this imported component faces issues like unstable lead times, cost fluctuations due to exchange rates, and slow technical support. These challenges hinder production schedules and cost control for downstream companies. Therefore, domestic substitution has become a necessity for ensuring supply chain security, reducing costs, and enhancing competitiveness.
VBsemi, with years of expertise in power semiconductors, introduces the VBL1615 N-channel power MOSFET based on independent R&D. This product is precisely benchmarked against the 2SK3434-Z-AZ, offering parameter upgrades, technological parity, and full package compatibility. It can be directly replaced without circuit modifications, providing a more stable, cost-effective, and locally supported solution for high-current electronic systems.
Comprehensive Parameter Surpassing, Ample Performance Redundancy, Adapting to More Demanding Conditions.
Tailored as a domestic alternative to the 2SK3434-Z-AZ, the VBL1615 achieves significant improvements in key electrical parameters:
Firstly, the continuous drain current is increased to 75A, significantly higher than the original model's 48A—a 56.3% enhancement. This allows handling higher power levels and improves system stability in demanding applications like motor drives and power supplies.
Secondly, the on-state resistance is as low as 11mΩ (@10V gate drive), superior to the 2SK3434-Z-AZ's 31mΩ (@4.0V). This reduction in conduction losses improves efficiency, reduces heat generation, and lowers cooling system requirements, especially in high-frequency switching scenarios.
Thirdly, the drain-source voltage is maintained at 60V, matching the original model for compatibility in low-voltage applications. The gate-source voltage of ±20V offers robust gate protection and noise immunity, while the 1.7V gate threshold voltage ensures easy driving with mainstream driver ICs, simplifying design integration.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core advantage of the 2SK3434-Z-AZ lies in its low on-resistance. The VBL1615 employs advanced Trench technology, optimizing device reliability and switching performance. It undergoes rigorous testing, including avalanche energy tests, ensuring durability against transient surges in automotive or industrial environments. The optimized capacitance structure reduces switching losses and enhances dv/dt tolerance, suitable for fast-switching applications. With an operating temperature range of -55°C to 150°C and passing reliability tests like high-temperature/high-humidity aging, the VBL1615 offers long-term stability for critical applications, reducing failure rates and ensuring uninterrupted operation.
Fully Compatible Package, Enabling "Virtually Cost-Free, Risk-Free, and Immediate" Replacement.
The VBL1615 uses a TO-263 package, identical to the 2SK3434-Z-AZ in pinout, dimensions, and thermal design. Engineers can replace it directly without PCB modifications or thermal system adjustments, achieving "plug-and-play" convenience. This compatibility reduces verification time to 1-2 days, avoids redesign costs, and ensures quick integration into existing production lines, accelerating the substitution process and minimizing downtime.
