- 75 V DC sparkover voltage with 10 kA peak impulse current rating for robust surge protection
- 2-electrode axial gas discharge tube (GDT) construction enabling high-voltage isolation and fast arc response
- EHV Series long-form round package compatible with through-hole PCB mounting and standard lead-free reflow up to 260°C
- Single-function discrete protection device suited for line-to-line and line-to-ground surge suppression
Applications
The B88069X0180T502 is used in telecom line protection circuits, industrial fieldbus interfaces, and power distribution panels where transient overvoltage events of up to 10 kA must be clamped at 75 V. It is integrated into the primary protection stage of DSL, POTS, and Ethernet surge protection modules. The axial through-hole package simplifies installation in DIN-rail-mounted surge arresters and equipment protection boards.

Frequently Asked Questions
What is the sparkover voltage and peak impulse current rating of the B88069X0180T502?
The B88069X0180T502 has a DC sparkover voltage of 75 V and a peak impulse current rating of 10 kA (8/20 µs waveform). These parameters make it suitable for protecting sensitive telecom and industrial equipment from high-energy transient surges without triggering under normal operating conditions.
How does the 2-electrode GDT construction of the B88069X0180T502 differ from 3-electrode gas tubes in surge protection designs?
A 2-electrode GDT like the B88069X0180T502 conducts surge current between a single pair of electrodes, making it ideal for line-to-ground or line-to-line protection on a single conductor pair. A 3-electrode version adds a middle electrode to protect two lines simultaneously with matched sparkover thresholds, but the 2-electrode design offers lower capacitance (typically <1 pF) and simpler integration for single-pair protection stages.
Is the B88069X0180T502 compatible with lead-free reflow soldering processes?
The B88069X0180T502 carries a JESD-609 code of e3, indicating it is rated for lead-free (Pb-free) processing with a peak reflow temperature of 260°C. However, it is a through-hole axial device (Surface Mount: NO), so it is typically wave-soldered or hand-soldered rather than reflowed on a standard SMT line.
What are the typical industrial and telecom applications for the B88069X0180T502 GDT?
This GDT is designed for primary surge protection in POTS telephone lines, DSL equipment interfaces, industrial RS-485 and Profibus ports, and power metering terminals where 75 V standoff voltage and 10 kA impulse withstand are specified. It is often placed in series with secondary protection components such as TVS diodes or PTC thermistors to create a multi-stage protection network.
