Additional Details

The P1500SDL is housed in a DO-214AA (SMB) package, ideal for surface mount assembly. Key electrical specifications include a breakover voltage of 150V and a surge current capability designed to withstand high-energy transients. It's engineered to quickly switch to a low-voltage on-state when an overvoltage condition occurs, diverting the surge current away from protected circuits. The low capacitance of the device makes it suitable for high-speed data lines where signal integrity is critical. This SIDACtor device is commonly used in conjunction with other protection components, such as fuses and TVS diodes, to provide comprehensive circuit protection.
