In the hidden corners of industrial power supplies and smart home appliances, a revolution in high-voltage power density is quietly taking place. VBE25R04 , the first domestic -500V/4A P-channel MOSFET using TO-252 package, carries industrial-grade high-voltage performance in a small body, bringing disruptive changes to LED drivers, smart meters and other scenarios.

 1. Breaking through technical barriers

1. The "slimming revolution" of high-voltage devices

-500V withstand voltage breakthrough : Achieving -500V blocking voltage in a TO-252 package of only 6.5×6.2mm, saving 70% space compared to traditional TO-220 solutions

4A current density : Through new planar process optimization, the current carrying capacity per unit area is 1.8 times that of competing products

Actual measurement comparison : In LED driver applications, the PCB area is reduced from 45cm² to 28cm², and the BOM cost is reduced by 22%.

2. A delicate balance between energy efficiency and reliability

3900mΩ@10V on-resistance : 15% lower than the industry average, temperature rise is only 18℃ at 2A operating current

-3V threshold voltage : compatible with 3.3V/5V control signals, eliminating the need for level conversion circuits

Extreme environment verification : passed 1000 times of -55℃~150℃ hot and cold shock tests.

2. Application Scenarios
