Protection ICs from STMicroelectronics Optimized to Protect Low-Noise-Block Voltage Regulators in Satellite Set-Top-Box Applications



New LNBTVS range protects against lightning and electrical overstress surges

Geneva, June 26, 2006 - STMicroelectronics (NYSE: STM), one of the world's largest semiconductor manufacturers and the world leader in protection devices according to independent market analyst iSuppli, has introduced the world's first family of devices specifically optimized to protect the Low Noise Block (LNB) voltage regulator in satellite set-top-box applications against lightning and electrical overstress surges. The LNBTVSx-22x range provides 3kV, 4kV and 6kV optimized protection (8/20µs) devices that fully comply with the LNB supply voltage and IEC61000-4-5 protection standards.

Because of their exterior mounting, satellite aerials and the LNB circuitry are vulnerable to lightning, which can cause current surges at the LNB voltage regulator inputs that typically range from 250A when 3kV is applied, to 500A when 6kV is applied. The voltage-regulator ICs cannot withstand such powerful energy pulses and require an external protection device. Although standard lightning protection devices are available, they are not optimized for this particular application.

The LNBTVS family benefits from ST's position as the world's leading supplier of semiconductor protection devices and the worldwide leader in LNB voltage regulators. ST's expertise has enabled the Company to offer a complete turnkey solution comprising the LNB voltage regulators and a companion protection device that is optimized for the satellite STB function, thereby outperforming standard solutions at lower cost.

Compatible with all LNB voltage regulator types, the LNBTVS devices offer low clamping voltage (VCL) from 30V to 35V for cost/performance optimization, fast response time, and a low forward voltage (VF) of 1.2V at IF = 3A. The devices are available in axial (DO-201) and SMD (SMB and SMC) packages, are UL recognized, and are in volume production. Prices range from $0.20 (3kV) to $0.45 (6kV) for 2500 pieces.
