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).
