Product Description
5.0x7.6mm Surface Mount 350V Gas Discharge Tube
2-electrode surface mount ceramic gas discharge tube with 350V DC spark over voltage and 5KA impulse discharge current rating.
Product Overview
Gas discharge tubes are protective devices that generate light by sending an electric discharge through ionized gas plasma, typically using noble gases like argon, neon, krypton, or xenon mixtures.

Engineering Selection Guide
Ceramic gas discharge tubes provide effective surge protection for AC/DC power supplies and signal lines by changing from high to low impedance during voltage spikes.
Key selection considerations:
- DC breakdown voltage should exceed 1.2 times the maximum operating voltage
- Impulse discharge current rating must match expected surge conditions
- Consider response time (0.1-0.3μs) and potential for secondary protection
- Address freewheeling concerns in active circuits with additional components
- Account for breakdown voltage tolerances in parallel applications
