Editor's note: STMicroelectronics, one of the world's leading manufacturers of power semiconductor products, has introduced the first product in a new series of power MOSFET products. The on-state resistance is extremely low, and the dynamic characteristics and avalanche characteristics are excellent. The new series offers customers the opportunity to significantly reduce the conduction loss of lighting applications and improve overall efficiency and reliability. ![]()
The ever-increasing demand for higher power density and lower cost in the commercial lighting application market is spurring semiconductor manufacturers to challenge the limits of device optimization. The new STD11NM60N is one example of the challenge of semiconductor device technology. The product uses ST's second-generation MDmeshTM technology. The maximum on-resistance RDS (ON) is 450 mΩ. The resistance of this device is lower than that of the previous generation MDmesh technology. 55%, and this excellent feature is not at the expense of precise control of its temperature characteristics. In addition to minimizing on-state losses by minimizing resistor values, the main features of this 600V product include an energy-efficient drive circuit that allows the MOSFET to be driven at a lower VGS(th) (gate-threshold) voltage. Higher current. In fact, although the threshold voltage range (2V) does not change, the VGS voltage range required to drive the device is reduced, thereby optimizing the performance of the driver circuit and ensuring that the device has excellent noise suppression performance that prevents the circuit from being accidentally turned on. Key features of the STD11NM60N include an excellent diode dv/dt performance and excellent avalanche characteristics, allowing the user to maintain operating temperatures within the normal operating temperature range. Because conduction losses and power consumption are low, the device also helps customers reduce the size of the heatsink, which saves board space. The chip's compact size, combined with the tiny DPAK/IPAK and TO-220FP packages, makes it ideal for lighting applications such as high power factor electronic ballasts and high intensity discharge lamp (HID) electronic ballasts. The STD11NM60N is now in volume production. Order 10,000 pieces for $0.90.
