The TDK T33-A230X is a 3-electrode gas discharge tube (GDT) designed for surge protection in telecommunication and industrial applications. It features a DC spark-over voltage of 230V ±20% (184V min, 276V max) and an impulse spark-over voltage typically below 440V at 1kV/µs rise rate. The device can handle impulse discharge currents of 10kA (8/20µs waveform) for up to 10 operations and 2kA for a single 10/350µs surge. Key electrical characteristics include very low capacitance (<1.5pF at 1MHz), high insulation resistance (>10GΩ at 50VDC), and fast response time with transverse delay time less than 0.2µs. The GDT is packaged in an axial cylinder with three leads (radial bend) for through-hole mounting. It operates over a temperature range of -40°C to +125°C and is RoHS-compatible. Typical applications include line protection, station protection, and base station surge suppression.
