JR2E5-SMD Series Surface Mount GDT | Compact SMD Gas Discharge Tube for Differential Line and Interface Protection
The JR2E5-SMD Series is a surface-mount 2-pole gas discharge tube (GDT) with ceramic housing and silver-plated terminals, optimized for SMT assembly. Designed for fast response (<1ns), high insulation, and low capacitance, it offers robust surge protection for space-constrained applications.
Typical breakdown voltages include 90V, 150V, 230V, 350V, 470V, and 600V. Rated up to 5kA (8/20μs), the series is ideal for RS485, RS422, CAN bus, PoE ports, metering interfaces, alarm systems, and compact power supply inputs.
