VDS=650V: Suitable for 220V/380V industrial systems and high-voltage buses, providing ample margin for voltage spikes, enhancing system avalanche capability.
VGS=±30V: Wide gate drive range, compatible with various driver outputs, reducing false turn-on risk and enhancing drive robustness.
Vth=3.5V (typical): Moderate threshold voltage, effectively suppressing dv/dt-induced high-frequency oscillations while ensuring reliable turn-off.
RDS(on)=160mΩ @ VGS=10V: Super-junction technology achieves low conduction loss, significantly reducing temperature rise under full load, simplifying thermal design.
ID=20A: Ample continuous current margin, covering the primary switch and PFC circuit requirements of most high-voltage power converters.
Package DFN8X8: Large exposed pad design, low thermal resistance, low parasitic inductance, supporting high-frequency switching while saving PCB area.
Domain and module applications：
Switching Power Supply (SMPS): Low on-resistance and low gate charge improve efficiency, suitable for high-efficiency AC-DC main switches.
Power Factor Correction (PFC) Circuit: 650V withstand voltage combined with fast switching characteristics meets low-loss requirements in continuous/critical conduction modes.
Photovoltaic Inverters: High voltage margin and low-loss characteristics enhance DC-AC conversion efficiency and improve long-term outdoor reliability.
Charging Piles and Onboard Chargers (OBC): High power density packaging and high current carrying capacity are suitable for high-power charging modules, reducing temperature rise.
Industrial Motor Drives: The super-junction structure has strong avalanche resistance, suitable for frequency converters and servo drives powered by high-voltage buses.
Server and Communication Power Supplies: High efficiency and the miniaturization advantage of DFN8X8 packaging aid in the design of high-density power modules.
LED High-Power Lighting Driver: Wide voltage range adapts to grid fluctuations, low voltage drop reduces driver stage power consumption. Selection Summary: TK28V65W, LQ-VB achieves a balance between high voltage withstand, low conduction loss, and compact packaging. It is a cost-effective general-purpose choice for 650V high-voltage switching applications, especially suitable for projects with strict requirements on power density, thermal management, and system efficiency.
