With the rapid development of semiconductor technology and the arrival of 5g era, all kinds of modern products are developing in the direction of high voltage, high current, high power and high frequency; the demand for small volume, low energy consumption and high efficiency product appearance is also increasingly strong. As an indispensable part of switching power supply, PC power supply, server power supply, adapter, photovoltaic inverter, UPS, lighting power supply, OBC, charging pile and other products, packaging products with smaller volume and higher efficiency of power semiconductor devices have been unanimously desired. The compact surface mount package (dfn8 * 8) has been launched by Mapson semiconductor in time to meet the needs of the times, which has attracted the attention of many application customers.

At present, the mainstream of high-power SMT shapes are TO-252 (DPAK), to-263 (d2-pak), dfn5 * 6 and so on. However, due to the limitation of package size and package capacity, the existing packages for the new generation of high-efficiency and small volume products are difficult to meet the demand, so dfn8 * 8 shape package emerges as the times require. Now let's understand the characteristics of dfn8 * 8 shape.

1、 Dfn8 * 8 package features:

Surface mount package

The package height is only 1 mm

■ creepage distance increased to 2.75mm

No pin design

■ enlarged base Island

Excellent thermal performance, similar to to to-263 (d-2pak)

Small size, convenient fit

2、 Package size comparison:

Dfn8 * 8 has more advantages and characteristics than traditional TO-252 and to-263 package sizes

1. The package size of TO-252 is 6.6 * 10 * 2.3 (mm);

The package size of to-263 is 10.2 * 15.15 * 4.7 (mm);

Dfn8 * 8 package size is 8 * 8 * 1.0 (mm), with smaller volume proportion in pasting.

2. The area of TO-252, to-263 and dfn8 * 8 are 66mm2, 154mm2 and 64mm2 respectively.

The area of DFN is more than 50% less than that of to-263.

3. The back fin areas of TO-252, to-263 and dfn8 * 8 are about 23mm ~ 2, 47mm ~ 2 and 34mm ~ 2, respectively.

Dfn8 * 8 back heat sink area is about 50% more than TO-252.

4. The height of TO-252, to-263 and dfn8 * 8 are 2.3mm, 4.7MM and 1mm, respectively

The height is less than TO-252 and to-263.

3、 Compared with traditional plug-in encapsulation:

Compared with the traditional TO-220, TO-247 and to-3pn packages, the SMD package greatly reduces the package size and optimizes the volume and space ratio. Dfn8 * 8 has lower parasitic inductance than TO-252 and to-263 due to its pinless design. The main cooling path is to pass the bare metal pad to PCB to improve the heat dissipation capacity of the package.

N the enlarged base island design can meet the requirements of plug-in power devices in package;

N excellent thermal conductivity, similar to to to-263 (d-2pak), directly adheres to PCB for heat dissipation;

N small volume design can greatly reduce the product space occupation;

N SiC diode, MOSFET (super junction, SiC MOSFET) synchronous packaging market, to meet the needs of more industries;

N excellent RDSON and vfsd are directly applied to more demanding projects;

4、 Practical project display:

Faster, smaller and more efficient is the direction of our engineers. In the fast-paced life of the new era, fast, efficient and convenient application experience has always been favored.

Established in 2014, Mapson semiconductor is located in Shekou, Nanshan District, Shenzhen, which is known as the forefront of China's reform and innovation. It is a complete industrial chain company integrating R & D, design, production, sales and service, and a national high-tech enterprise.

Main power MOSFET (power MOS), trench MOSFET (low voltage MOS), super junction MOSFET (super junction MOS), SiC MOSFET (silicon carbide MOS), SiC diode (silicon carbide diode) and other products.

The new dfn8 * 8 superjunction MOSFET of Mapson semiconductor has been in full swing since it was launched into the market. Here is an example of the application of Mapson products (sll65r170e7) in the PD fast charging industry.
