 Geneva,
October 8, 2004 - STMicroelectronics (NYSE: STM) has introduced more
low-voltage N-channel MOSFETs based on its STripFET technology. They are
designed for very high frequency switching applications, making them attractive
for computer motherboards and telecom.The STripFET technology uses an optimized layout and updated manufacturing process to improve the gate charge, gate resistance and input capacitance characteristics. The low gate charge enables excellent switching behavior and the low gate resistance means fast transient response. The technology also offers an extremely low figure-of-merit, meaning reduced conduction and switching losses. The parts being launched by STMicroelectronics include the STS12NH3LL, STSJ50NH3LL, STD55NH2LL, STD95NH02L, STL8NH3LL and STL50NH3LL. The STS12NH3LL is a 30V part rated at 12A. The STSJ50NH3LL is a 30V part rated at 50A. Both offer a typical On-resistance of 0.008 Ohm at 10V and an optimal trade-off between On-resistance and gate charge at 4.5V. Both are designed for use in high-frequency DC-DC converters for telecom applications and in power management circuits for laptops. The STS12NH3LL is available in an SO-8 package and the STSJ50NH3LL in a PowerSO-8 package. The STD55NH2LL is a 24V part rated at 55A. Typical On-resistance is 0.01 Ohm at 10V or 0.012 Ohm at 4.5V. The part has been designed for use in high-efficiency DC-DC converters. It is available in through-hole mounting IPAK (TO-251) or a surface-mounting DPAK (TO-252) packages. The STD95NH02L is a 24V part rated at 80A. Typical On-resistance is 0.0039 Ohm at 10V and 0.0055 Ohm at 5V. Due to a very low gate charge, this device shows a typical value of 136.5nC*Qg at 10Vof figure-of-merit, that is the best available in the market. It is available in a surface-mounting DPAK (TO-252) package. The STL8NH3LL and STL50NH3LL are being launched in PowerFLATTM packages, which offer an improved die-to-footprint ratio, a low profile and low thermal resistance. The STL8NH3LL is a 30V part rated at 8A. Typical On resistance is 0.012 Ohm at 10V. It is available in a 3.3 x 3.3mm PowerFLATTM package. The STL50NH3LL is a 30V part rated at 27A. Typical On-resistance is 0.011Ohm at 10V. It is available in a 6 x 5mm PowerFLATTM package. Both parts have been designed for use in synchronous rectification circuits in isolated DC-DC converters, and as a control FET in buck converters. All parts are available now, with prices ranging from US$0.285 to US$0.485 in quantities of 300K units.
