Overview
The EPCOS B88069X8350B502 is a robust 3-pole Gas Discharge Tube (GDT) designed for high-energy surge suppression, offering a nominal DC spark-over voltage of 90V and an impressive 10kA impulse discharge capability. Its primary function is to protect sensitive downstream circuitry from transient overvoltages, particularly in applications where lightning strikes or switching transients are a concern. A critical design consideration for GDTs like this is the trade-off between spark-over voltage and leakage current; while a lower spark-over voltage offers better protection, it can also lead to increased quiescent current, which is undesirable in many low-power systems. The B88069X8350B502 balances these factors effectively for broad applicability.
