Introduction

The localization replacement of core components for industrial inverters has become the key to reducing costs and improving efficiency in the manufacturing industry. Imported MOSFETs generally face three major pain points: lead times as long as 3-6 months that cause production delays, high-frequency switching losses that reduce equipment efficiency, and complex heat dissipation designs that drive up costs. As a domestic alternative, Heketai HKTD120N04 provides an ideal choice for inverter manufacturers with its low on-resistance, fast delivery, and industrial-grade reliability.

Localized Supply Chain Assurance

1. Rapid Response Capability

Through its dual-base layout in South China (Huizhou/Dongguan) and Southwest China (Nanchong, Sichuan), Heketai achieves 24-hour off-the-shelf delivery and has maintained a 100% on-time delivery rate over the past three years. Compared with the 3-6 month lead time of imported brands, it completely solves the "waiting for materials to keep production going" dilemma. It maintains a stock of 10 billion components covering 12,000 models, supporting "one-stop procurement," and samples can be delivered for testing within 3 days.

2. Supply Chain Stability

A 6,000 m² temperature-and-humidity-controlled intelligent warehouse ensures the quality of product storage, and a 99.8% production yield reduces quality risks. The domestic direct supply model avoids tariffs and logistics fluctuations, and the vertical integration capability from raw materials to finished products ensures the stable operation of the supply chain even under extreme conditions.

Outstanding Performance Advantages of the Product

1. Low On-Resistance and Energy Efficiency Improvement

The HKTD120N04 achieves an ultra-low on-resistance of 1.7 mΩ, which is approximately 80% lower than that of similar imported products (e.g., 8 mΩ of IRF3205). Under the working condition of 100A current, the power consumption is reduced from 80W to 17W. Combined with the 15ns fast switching characteristic, the switching loss is reduced by 35%, increasing the overall efficiency of the inverter from 90% to 93.5%.

2. Industrial Scene Adaptability: Wide Temperature Range and High Reliability

• Operating temperature range: -55℃ ~ +150℃, suitable for extreme environments such as metallurgy and cold storage
• High-temperature stability: Continuous operation at 150℃ for 1,000 hours with a leakage current change ≤ 5%
• Heat dissipation optimization: TO-252 package combined with copper foil reduces the junction temperature by 15℃

3. Industrial Scene Adaptability: High Load Durability

With a continuous drain current output of 120A and an avalanche energy of 70mJ, it can withstand a peak current impact of 150A during motor startup and reduce electromagnetic interference. Each batch of products undergoes avalanche testing and thermal resistance testing, reducing the failure rate by 80%.

Cost-Benefit Analysis

1. Direct Cost Savings

• Procurement cost: 30% lower than imported brands, eliminating 10% tariffs and 5% logistics costs
• Energy consumption optimization: A 10kW inverter saves 2,000 kWh of electricity annually; calculated at an industrial electricity price of 1 yuan/kWh, this results in an annual electricity cost savings of 2,000 yuan
• Maintenance reduction: For a scale of 1,000 units, 8 failures are reduced annually, saving 16,000 yuan in maintenance costs

2. Long-Term Value

The total cost of ownership is 40% lower than that of imported solutions. Meanwhile, it has obtained ISO 14001 certification, helping enterprises achieve their ESG (Environmental, Social, and Governance) energy conservation and emission reduction goals.

Conclusion

In summary, the HKTD120N04, with its three core advantages—24-hour rapid delivery, ultra-low on-resistance, and ultra-wide temperature operation—has become an ideal choice for industrial inverters. It not only solves the pain points of lead time and cost of imported brands but also creates long-term value for enterprises through improved energy efficiency and optimized reliability.
