Additional Details

The TISP4240F3LP operates by clamping the voltage across the protected circuit to a safe level during a surge event. The device is designed for surface mount assembly. Key specifications include the peak pulse current (Ipp), the breakover voltage (Vbo), and the holding current (Ih). Proper PCB layout is critical for optimal surge protection performance. Bourns provides detailed datasheets and application notes to assist in selecting and implementing surge protection solutions. By integrating surge protection components like the TISP4240F3LP, designers can significantly improve the robustness of their systems against transient overvoltage events, ensuring reliable performance and minimizing the risk of equipment failure. Selecting the appropriate Transient Voltage Suppressors (TVS) is a critical step in designing reliable and resilient electronic systems.
