## Description

The Bourns 2030-23T-SM-RPLF is a fast-acting three-electrode gas discharge tube (GDT) designed for surface-mount deployment in compact circuit protection architectures. This miniature GDT features a 5 mm diameter cylindrical ceramic body with 7.3 mm overall length, packaged in a three-terminal SMD configuration suitable for automated assembly processes. The device exhibits a DC sparkover voltage of 185 V minimum (measured at 100 V/s ramp rate) with a maximum impulse sparkover voltage of 650 V under 5 kV 1.2/50 µs surge conditions. Critical surge handling capability includes an 8/20 µs impulse discharge current rating of 4 kA, with the rated current equally divided between line-to-ground paths. The GDT maintains ultra-low capacitance below 1 pF at 1 MHz, ensuring minimal signal degradation in high-speed data lines. DC holdover voltage is specified at 80 V with recovery time under 150 ms when tested per ITU-T K.12 network conditions.

Engineered for coordinated protection schemes, the 2030-23T-SM-RPLF is specifically designed to operate in conjunction with Bourns TBU® transient blocking unit devices, forming robust surge protection networks for industrial and communication interfaces. Typical applications include CAN bus, RS-232, RS-422, RS-485, and SDI port protection, where the three-electrode configuration enables common-mode and differential-mode transient suppression in a single component. The device operates across -40°C to +90°C ambient conditions with stable breakdown characteristics throughout service life. Insulation resistance exceeds 10¹⁰ Ω, while glow-to-arc transition current remains below 0.5 A. The RPLF suffix denotes RoHS-compliant material construction on 18 mm reelpack packaging (1,000 pieces per 330 mm diameter reel). UL recognized and IEC 60068-1 climatic category 40/90/21 rated, this GDT suits telecommunications infrastructure, industrial electronics, and avionics systems requiring reliable overvoltage protection in space-constrained designs.

## Notes: 

1 The rated discharge current is the total current equally divided between each line to ground and operation(s) are performed in both polarities. The polarity of lightning surge tests should be reversed between consecutive surges. 2 Per IEC 61643-21. 

- At delivery AQL 0.65 Level II, DIN ISO 2859.
