SLIC protection device with peak pulse current upto 75A

STMicroelectronics has unveiled the LCP12 IC to protect against high-voltage surges on the tip and ring connections of Subscriber Line Interface Cards (SLICs), which connect telecom local loops to the access network. These voltage surges can be caused by lightning strikes or by electromagnetic coupling or direct contact with AC power lines.

The LCP12 provides the protection specified by telecom standards used throughout the Americas, Europe and the Far East, such as the GR-1089 CORE standards, ITU-T-K.20/21 covering operator and customer-premises equipment, and the similar Mainland China YD/T standards. As the only protection device rated for surge currents up to 75A for the 5/310us waveshape at 4kV, as per ST.

Key features of LCP12 include:
Peak pulse current: 45A (10/1000us), 75A (5/310us)
Compliant with standards:
GR-1089 Core First-Level/Second-Level/Intra-Building
ITU-T-K20/K21
ITU-T-K20 (IEC 61000-4-2 ESD contact/air discharge)
VDE0433, VDE0878
IEC 61000-4-5
TIA-968-A (formerly FCC part 68type A)
TIA-968-A (formerly FCC part 68) type B)
Wide firing voltage range: -120V to +120V
Low gate triggering current: IG = 5mA maximum
Holding current: 150mA minimum

Availability, package and pricing: The LCP12 is housed in the SO-8 wide package and is available to qualified customers, priced from $1.196, with a minimum order quantity of 1000 pieces.
