The SH Series Gas Discharge Tube (GDT) is designed to provide high levels of protection against fast-rising transients caused by lightning disturbances. It is offered in a squared surface mount package (5.0×5.0×4.2mm) with a 5kA surge capability and a ≤0.7pF off-state capacitance value.
- 5kA surge capability in minimal footprint (5.0×5.0×4.2mm)
- Ultra-low capacitance (< 0.7 pF) that does not vary as the signal voltage varies
- Surface mount form factor with squared body and terminals
