## **Description** 

The LNBTVS series has been designed to protect LNB voltage regulators in satellite set top boxes against electrostatic discharges according to IEC 61000-4-2, and MIL STD 883, method 3015, and electrical over stress according to IEC 61000-4-4 and 5. These devices can protect against surges up to 6 kV over the whole consumer temperature range (up to 85 °C). 

Planar technology makes these devices suitable for high-end set top boxes to provide reliability and stability over time. 

LNBTVS are packaged in either SMB or SMC (footprints in accordance with IPC 7531 standard).

LNBHxx output is usually connected to the antenna cable of digital satellite receivers. Atmospheric phenomenon can cause high voltage discharges on the antenna cable causing damages to the attached devices. 

In applications where it is required to be protected against lightning surges, transient voltage suppressor (TVS) devices like LNBTVSx-22xx can be used to protect LNBHxx and the other devices electrically connected to the antenna cable. 

The LNBTVSx-22xx diodes are dedicated lightning and electrical overstress surge protection for LNBHxx voltage regulators. These protection diodes were designed to comply with the stringent IEC 61000-4-5 standard with surges up to 500 A with a whole range of products. 

TVS diodes have intrinsic capacitance that attenuates the RF signal. For this reason, the LNBTVSx-22xx cannot be directly connected to the IF (RX/TX) cable connector that carries the RF signals coming from the LNB. To suppress the effect of the intrinsic capacitance, an inductance must be placed in series with the TVS diode (see _Figure 9_ ). The goal of the L series and LNBTVC inductance is to be transparent at 22 kHz and to reject frequencies higher than 900 MHz. 

The value of the series inductance is usually > 13 nH, with a current capability higher than the Ipp (peak pulse current) expected during the surge.
