Bourns' Model 2003 series is a 2-electrode GDT designed for use in applications that may be exposed to lightning or other transients. The compact GDT offers a maximum 2 kA, 8/20 μsec peak pulse current rating, fast response times and stable performance over its extended life.

The Model 2003 series has extremely low capacitance, making it an ideal overvoltage protector for high-speed telecom customer premises equipment (CPE) or industrial communications applications.
