LCP02-150B1RL Description

Short technical summary and product information.

The LCP02-150B1RL is a protection IC developed by STMicroelectronics for use in ringing SLICs (Subscriber Line Interface Circuits). It provides crowbar mode protection for both TIP and RING lines using two thyristor structures, one for positive surges and one for negative surges. The device features a wide firing voltage range from -110V to +95V, programmable via two gates (Gn and Gp).

 

Key electrical specifications include a peak pulse current of 30A under 10/1000µs waveform, 45A under 5/310µs, and 65A under 1/20µs. The gate trigger current is 5mA maximum, and holding current is 150mA minimum. The total battery supply voltage can be up to 190V. The device also specifies non-repetitive surge peak on-state currents for various durations.

 

The LCP02-150B1RL is housed in a surface-mount 8-SOIC package with a width of 5.30mm. It supports an operating temperature range of -20°C to 85°C and storage from -55°C to 150°C. The device is UL497B approved (file E136224) and uses UL94-V0 rated resin.
