In various power switching scenarios such as motor drives, DC-DC converters, power supplies, and automotive systems, RENESAS IDT's 2SK2723-AZ, with its reliable construction and consistent performance, has been a trusted selection for engineers globally. However, amidst post-pandemic supply chain disruptions and international trade volatilities, this imported component reveals growing pains: unpredictable lead times (often extending months), costs vulnerable to currency fluctuations, and sluggish technical support. These challenges critically impact production schedules and cost management for downstream enterprises. Thus, domestic substitution has shifted from an "alternative" to a "imperative," serving as a vital strategy for ensuring supply chain security, reducing expenses, and strengthening core competitiveness.
VBsemi, drawing on years of dedication in power semiconductor innovation, introduces the VBM1638 N-channel MOSFET through independent R&D. This product is precisely aligned to replace the 2SK2723-AZ, delivering core advantages of parameter enhancements, technological equivalence, and full package compatibility. It acts as a direct drop-in replacement without any modifications to original circuits, offering a more stable, cost-efficient, and locally attuned high-quality solution for diverse power electronic systems.
Comprehensive Parameter Advancements, Ample Performance Headroom for More Demanding Conditions.
Designed as a domestic alternative to the 2SK2723-AZ, the VBM1638 achieves across-the-board improvements in key electrical parameters, providing stronger performance guarantees:
First, the continuous drain current is doubled to 50A, a 100% increase over the original model's 25A. This significant boost in current-carrying capability effortlessly supports higher-power circuit designs, whether upgrading equipment to higher power levels or enhancing system stability at existing ratings.
Second, the on-state resistance is reduced to 24mΩ (@10V gate drive), substantially lower than the 2SK2723-AZ's 40mΩ (@10V, 13A)—a 40% reduction. This minimizes conduction losses, directly improving overall efficiency and reducing heat generation, thereby easing thermal design pressures and lowering cooling costs.
Third, the drain-source voltage maintains 60V, matching the original rating for compatibility in standard applications. Additionally, the VBM1638 supports a ±20V gate-source voltage, offering stronger gate ESD protection and noise immunity, effectively preventing accidental turn-on in complex electromagnetic environments. The 1.7V gate threshold voltage balances drive convenience and switching reliability, seamlessly interfacing with mainstream driver ICs without requiring drive circuit adjustments, further simplifying substitution.
Enhanced with Advanced Trench Technology, Reliability and Switching Performance Elevated.
The 2SK2723-AZ is recognized for its dependable performance, but the VBM1638 employs advanced Trench gate technology, optimizing device characteristics for higher efficiency and robustness. This technology delivers low on-resistance and fast switching speeds, reducing switching losses and improving dv/dt tolerance. The device undergoes rigorous pre-shipment testing, including avalanche energy validation and high-voltage screening, ensuring durability under transient surges. With an operating temperature range of -55°C to 150°C, it adapts to harsh conditions such as industrial high-temperature environments or outdoor extremes. Reliability is further validated through extended aging tests (e.g., high-temperature/high-humidity), resulting in a failure rate well below industry averages, making it suitable for critical applications like automotive electronics, industrial controls, and renewable energy systems.
Fully Compatible Package, Enabling "Plug-and-Play" Replacement with Zero Risk.
For downstream companies, a primary concern in domestic substitution is the R&D investment and time cost. The VBM1638 eliminates this pain point through its package design. The device uses a TO-220 package, identical to the 2SK2723-AZ's TO-220 in pinout, pin spacing, dimensions, and heatsink mounting. Engineers need not alter PCB layouts or thermal designs, achieving seamless "plug-and-play" replacement. This high compatibility reduces verification time dramatically—sample validation often completes within 1-2 days—while avoiding costs from PCB revisions or mold changes. It also preserves original product certifications and外观 designs, accelerating supply chain transitions and helping enterprises swiftly adopt domestic alternatives to seize market opportunities.
Local Strength Assurance, Dual Peace of Mind for Supply Chain Security and Technical Support.
Compared to imported components plagued by international logistics delays, trade policies, and exchange rate risks, VBsemi leverages China's mature semiconductor industry chain, with modern production bases and R&D centers in Jiangsu, Guangdong, and beyond. This enables full-process independent R&D and stable mass production of the VBM1638. Current standard lead times are compressed to within 2 weeks, with expedited orders enabling 72-hour fast delivery. This mitigates risks from global supply chain volatility, tariffs, and geopolitics, ensuring smooth production planning. Simultaneously, as a local brand, VBsemi offers a professional technical support team with "one-on-one" customized services: comprehensive documentation including substitution verification reports, detailed datasheets, thermal design guides, and application circuit references, plus tailored selection advice and circuit optimization based on specific customer needs. Technical issues during substitution receive rapid responses within 24 hours, with onsite or remote resolution,彻底addressing the slow support and high communication costs of imported components, making the substitution process smoother and worry-free.
From motor drives and power supplies to automotive systems and inverters; from industrial equipment to consumer electronics, the VBM1638, with its core strengths of "higher current capacity, lower on-resistance, package compatibility, controlled supply, and responsive service," has become the preferred domestic replacement for the 2SK2723-AZ. It has already seen adoption in leading companies across multiple industries, gaining significant market recognition. Choosing the VBM1638 is not merely a component swap; it is a strategic step for enterprises to upgrade supply chain security, optimize production costs, and enhance product competitiveness—requiring no R&D modification risks while enjoying superior performance, stable supply, and convenient local support.
