SMD1206-301 Alternative / Equivalent / Replacement

Introduction

The SMD1206-301 is a 300V Gas Discharge Tube (GDT) in the compact SMD1206 surface-mount package. It protects sensitive signal and control lines from lightning-induced surges and power cross conditions by providing a low-impedance path during overvoltage events.

Product Overview

YINT Electronics SMD1206-301 has a DC spark-over voltage of 300V (measured at 100V/s ramp rate) and an impulse spark-over voltage of 950V (1kV/µs). The device handles impulse discharge current up to 0.5kA (8/20µs) with an ultra-low capacitance of 0.3pF, ensuring minimal signal degradation.

This GDT is available in SMD1206 tape-and-reel packaging (2000 pcs/reel), making it ideal for automated SMT assembly in telecom, Ethernet, and RF applications where high-speed data integrity matters.
