Datasheet - production data
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).
