The LS5120B from STMicroelectronics is a TRISIL device engineered for bidirectional crowbar protection. This component is specifically designed to safeguard telecommunication equipment from transient overvoltages, including those induced by lightning strikes and AC power lines.
Key electrical characteristics include a stand-off voltage of 100V and a breakdown voltage of 120V for the LS5120B variant. It boasts a high surge current capability, with a peak pulse current of 100A for a 10/1000 μs waveform and 250A for an 8/20 μs waveform. The device also features a non-repetitive surge peak on-state current of 50A at 20ms.
With a holding current of 250mA minimum and a critical rate of rise of on-state current at 100A/μs, the LS5120B ensures robust protection. The junction to ambient thermal resistance is rated at 80°C/W. The device is housed in a DIL8 package.
This series complies with various standards, including CCITT K17-K20, VDE 0433, and CNET, making it suitable for demanding protection applications where low series resistance is critical.
