In various low-voltage, high-current application scenarios such as power management systems, motor drives, battery protection circuits, DC-DC converters, and automotive electronics, RENESAS IDT's 2SJ330-AZ, with its efficient switching performance and robust design, has been a trusted choice for engineers worldwide. However, in the post-pandemic era marked by global supply chain disruptions and trade uncertainties, this imported component faces significant challenges: unpredictable lead times (often extending to 4-8 months), costs vulnerable to currency fluctuations, and sluggish technical support responses. These issues hinder production schedules and cost optimization for downstream enterprises, making domestic substitution not just an option but a strategic imperative for ensuring supply chain resilience, reducing expenses, and enhancing core competitiveness.
Leveraging years of expertise in power semiconductors, VBsemi introduces the VBM2625 P-channel power MOSFET through independent R&D. This product is meticulously designed to replace the 2SJ330-AZ, offering superior parameter upgrades, technological equivalence, and full package compatibility. It serves as a drop-in replacement without circuit modifications, delivering a more stable, cost-effective, and locally supported high-quality solution for low-voltage electronic systems.
Comprehensive Parameter Surpassing, Enhanced Performance Margins, Adapting to Demanding Conditions.
Tailored as a domestic alternative to the 2SJ330-AZ, the VBM2625 achieves leapfrog improvements in key electrical parameters, providing stronger guarantees for high-current applications:
First, the drain-source voltage is rated at -60V (absolute value 60V), matching the original model's 60V but with optimized robustness for low-voltage environments, ensuring reliability in systems with voltage spikes or transient noises.
Second, the continuous drain current is boosted to -50A (absolute value 50A), a 150% increase over the original model's 20A. This substantial enhancement in current-carrying capability enables seamless adaptation to higher-power designs, whether upgrading existing equipment or improving stability in same-power applications.
Third, the on-state resistance is drastically reduced to 19mΩ (@10V gate drive), significantly lower than the 2SJ330-AZ's 90mΩ (@4V). This reduction minimizes conduction losses, directly improving system efficiency and reducing heat generation, thereby easing thermal management demands and lowering energy costs in high-frequency switching scenarios.
Additionally, the VBM2625 supports a ±20V gate-source voltage, offering enhanced gate ESD protection and noise immunity, preventing false triggering in complex electromagnetic environments. The -1.7V gate threshold voltage balances drive convenience and switching reliability, seamlessly compatible with mainstream driver ICs without requiring drive circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Stability Inherited and Upgraded.
The core strength of the 2SJ330-AZ lies in its efficient switching and low losses. The VBM2625 employs industry-leading Trench technology, building upon the original model's performance while optimizing reliability across multiple dimensions. The device undergoes rigorous pre-shipment testing, including avalanche and high-voltage screening, demonstrating excellent single-pulse avalanche energy tolerance. It handles energy surges during switching with ease, reducing the risk of device failure from overvoltage events. Through optimized intrinsic capacitance design, it not only lowers charge/discharge losses but also enhances dv/dt tolerance, ensuring stable operation under high-frequency switching and fast transients, directly matching the 2SJ330-AZ's application profiles. Furthermore, the VBM2625 features a wide operating temperature range, typically from -55°C to 150°C, adapting to harsh conditions like industrial high-temperature environments or outdoor extremes. Having passed extensive reliability tests such as high-temperature/high-humidity aging, its failure rate is well below industry averages, providing solid assurance for long-term, uninterrupted operation—ideal for critical fields like automotive, industrial control, and renewable energy systems.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Risk.
For downstream enterprises, a key concern in domestic substitution is the R&D investment and time required. The VBM2625 addresses this through its package design. The device uses a TO-220 package, identical to the 2SJ330-AZ in pinout, pin spacing, dimensions, and heatsink structure. Engineers can directly replace the component without altering PCB layouts or thermal designs, achieving true "plug-and-play" convenience. This high compatibility reduces substitution verification time to 1-2 days for sample testing, eliminates costs from PCB revisions or mold adjustments, and preserves original product certifications and外观 designs. It effectively shortens supply chain cycles, helping enterprises swiftly transition from imported components and capture market opportunities.
