These two devices are the first low-voltage-PowerMOSFETs to use NEC Electronics' new SuperJunction1 technology. The advantage of this technology: By adding P-doped regions below the active P-well of the trench cells and reducing the resistance of the N-epitaxial layer through higher doping while maintaining an extremely low on-resistance, the structure width can be significantly enlarged and the gate charge thus reduced. Therefore, compared with the UMOS-4 trench technology, this results in a potential reduction of more than 30%.
Typical fields of application for PowerMOSFETs, manufactured using SuperJunction1 technology, are those where it is important to switch high currents as efficiently as possible within a short time. These include electric power steering (EPS) or also industrial drives in the low-voltage field e.g. in forklift trucks or in other battery-operated systems.
The new devices, in a popular D2PAK package, operate with drain-source voltages of 40 V and 55 V. Like all members of the NP series, the new devices are qualified to AEC-Q101, support a channel temperature of up to 175°C and are fully RoHS-compliant thanks to tin-plated leads.
Samples and data sheets of the low-voltage-PowerMOSFETs, NP110N04PUJ and NP110N055PUJ, are available now from Gleichmann Electronics. According to NEC Electronics, volume production is scheduled to start during the first half of 2009.
