• IP20 rating means it's finger-safe as it resists objects larger than 12.5mm
• Safe to use in challenging settings, thanks to an operating temperature range between -25°C and +70°C
• Surge voltage withstand rating of 4kV means it handles high power surges without suffering damage
• Durable metal holder holds firm against wear and impact in harsh environments

The diode serves as a protective device. It discharges excess voltage and carries it to the ground, reducing the risk of electric shocks and fire outbreaks.
