China's home appliance manufacturing industry has already captured 70% of the global market share, with the vacuum cleaner sector leading the world with an even higher 80% share. However, reliance on imported core components remains a pain point for the industry. Hekotai Semiconductor, having deeply rooted in the power device field for many years, has launched the HKTD70N04 field-effect transistor as an ideal domestic alternative to models such as AON6236, providing a high-performance and highly reliable solution for DC motor drives in vacuum cleaners.

Product Advantages: Dual Breakthroughs in Parameters and Performance

1. Precise Matching of Key Parameters

• Voltage/Current Specifications: 40V drain-source voltage (VDS) and 70A continuous drain current (ID) far exceed the drive requirements of conventional vacuum cleaner motors. The peak pulse current can reach 280A, effectively handling the large current impact during motor startup.
• Ultra-Low On-Resistance: Typical RDS (ON) is 7.5mΩ @ VGS=10V, with a maximum of only 9.5mΩ, reducing conduction loss and improving overall machine energy efficiency.
• Wide Temperature Operating Range: Junction temperature ranges from -55℃ to +150℃, adapting to the complex working conditions of vacuum cleaners.

2. Excellent Performance Empowers Efficient Driving

• High-Speed Switching Characteristics: Turn-on delay time (td (on)) of 7ns, turn-off delay time (td (off)) of 25ns, and rise/fall times (tr/tf) of only 5ns, meeting the needs of high-frequency PWM speed regulation.
• High Avalanche Energy Tolerance: Single-pulse avalanche energy (EAS) of 66mJ enhances the circuit's anti-surge capability.
• High-Density Cell Design: Adopting advanced trench technology to achieve low gate charge (Qg=58nC) and low reverse transfer capacitance (Crss=188pF), optimizing switching loss.

Application Scenario: Customized for Vacuum Cleaner Motor Drives

The HKTD70N04 uses a TO-252 package, with a compact design suitable for the narrow internal space of vacuum cleaners. Its motor drive-specific features include:

• Precisely controlling voltage and current output to ensure stable vacuum cleaner speed.
• Quickly responding to speed regulation commands to achieve stepless suction adjustment.
• Excellent temperature characteristics ensuring reliability during long-term continuous operation.
• Verified by vacuum cleaner manufacturers in actual machine tests, fully replacing AON6236 for seamless switching.

Alternative Advantages and Technical Support

1. Multi-Model Compatible Replacement

Directly replaces models such as AON6236 and ZM042N04N, with fully compatible pin definitions and package sizes, eliminating the need to modify PCB designs.

2. Full-Process Technical Services

Provides free sample testing, Hekotai FAE technical support, and stable supply guarantees.

Selection Recommendation

In the design of DC motor drives for vacuum cleaners, the HKTD70N04 field-effect transistor is recommended as the preferred choice. Its 70A high current capacity and high-speed switching characteristics can significantly improve motor efficiency and system stability, facilitating the upgrade of domestic alternatives.
