What are the main features of the TDK B88069X2331T902?
The TDK B88069X2331T902 is a 3-pole surface-mount gas discharge tube (GDT) designed for surge protection applications. It features a 90 V DC spark-over voltage, high surge current handling capability up to 5 kA, low capacitance, high insulation resistance, and a compact SMD package. These characteristics help protect sensitive electronic circuits from transient overvoltage events while maintaining signal integrity.
What is the B88069X2331T902 used for?
The B88069X2331T902 is commonly used to protect telecommunications equipment, industrial control systems, networking devices, security systems, and data communication lines from lightning strikes and other surge-related events. It safely diverts excessive surge energy away from sensitive components, helping improve system reliability and longevity.
Does the B88069X2331T902 have alternative manufacturers and part numbers?
Yes. Similar gas discharge tube surge protectors are available from manufacturers such as Littelfuse, Bourns, and Eaton. Common alternatives include the Littelfuse SL1003A090C, Littelfuse GTCR36-900M-R10, and selected Bourns 2038 or 2049 Series devices with comparable voltage and surge-current ratings. Alternative parts should be selected based on spark-over voltage, surge capability, package type, and application requirements.
Is technical support available for the B88069X2331T902?
Yes. Technical support is typically available through TDK, authorized distributors, and component suppliers. Support services may include datasheet assistance, application guidance, surge protection design recommendations, equivalent-part selection, PCB layout advice, and product availability information.
