Xinyan Semiconductor: The "Gold Standard" in Medium and Low Power Applications – Advantages and Applications of TO-252 Package MOSFETs

As a National High-Tech Enterprise focused on the R&D, design, and sales of medium and low voltage power MOSFETs, Xinyan Semiconductor's TO-252 (also known as DPAK) package series has become the "gold standard" in the medium and low power application field, thanks to its outstanding performance and high reliability. Below is a detailed analysis of its core advantages and broad application prospects.

Core Technical Advantages of the TO-252 Package

TO-252 is a surface-mount power package that achieves an excellent balance between power density, thermal performance, and assembly convenience. Xinyan Semiconductor leverages advanced trench process and Shielded Gate Trench technology to deliver electrical performance in this package that rivals international first-tier brands.

• Excellent Thermal and Power Handling Capability: The package integrates a large exposed metal thermal pad on its bottom, which can be directly soldered onto the PCB copper. This design utilizes the PCB as an "extended heatsink," significantly improving heat transfer efficiency. It can handle power dissipation up to 50-100W.

• High Power Density and Space Saving: With its compact size (approx. 6.5×10×2.3mm), it saves over 70% PCB area compared to traditional through-hole TO-220 packages, aligning with the trend towards device miniaturization and high-density integration.

• Low Parasitic Parameters and High-Frequency Performance: Its short internal leads and very low source/loop inductance help reduce switching voltage spikes, improve efficiency, and minimize EMI interference. It supports switching frequencies from several hundred kHz up to MHz levels.

• High Reliability and Process Friendliness: The robust molded package structure passes JEDEC standard reliability tests. Its standard surface-mount design is fully compatible with automated SMT production lines, significantly reducing assembly costs.

• Outstanding Cost-Effectiveness: With comparable performance, the TO-252 can save 20%-30% in packaging material costs compared to larger packages like TO-263. It also lowers system-level costs associated with PCB layout and thermal design.

Xinyan Semiconductor's Representative TO-252 Products and Performance

The company offers a wide range of TO-252 products covering various voltage and current ratings, for example:

• XYD60N26: Utilizing TO-252 package, it features 60V drain-source voltage, 26A continuous drain current, and an ultra-low on-resistance of approximately 26mΩ. Its operating temperature range covers -55°C to +150°C.

• XYD100N21: Employing an industrial-grade TO-252 package, with a 21V threshold voltage suitable for low-voltage, high-current applications. Its low on-resistance design effectively reduces losses and improves power conversion efficiency.

• High-Voltage MOSFET Series: The company has also launched 650V high-voltage MOSFET series, with models like 4N65 and 7N65 available in TO-252 package, suitable for medium and low-power switch-mode power supplies, PD fast chargers, and similar applications.

These products offer performance directly comparable to mainstream international models from brands like Infineon, onsemi, and ST, while holding a clear advantage in price/performance ratio.

Broad Application Areas

Leveraging its "small yet powerful" characteristics, the TO-252 package demonstrates strong application potential in several high-growth fields:
