DA53

The DA53 uses Micro-Gap technology which is accurate to tens of microns for accuracy and for rapid response against induced lightning and electrostatic discharges.
Ideal for protecting power supplies from power line voltage surges.

Features

• Small size (φ5.3mm, 10mm length).
• Compliant with various AC withstanding voltage tests
• Protects power supplies and voltage converters.
• Quick response against surge voltage, low limiting voltage.
• Small capacitance and high insulation resistance.
• Stable for repeated discharge tests and for many environmental fluctuations.
• No polarity.
• No dark effect.
• The DA53 series surge absorber in series with a varistor is used for surge protection in many types of power supplies and inverters.
