The P1800ECL is a SIDACtor® device from Littelfuse designed to protect sensitive electronic equipment from overvoltage transients. It is primarily used for telecom applications, providing robust protection against lightning surges and other voltage spikes on communication lines. These devices are known for their high surge current capability and low voltage overshoot.

Applications:

• Telecom Line Protection: Protecting telephone lines, modems, and other communication equipment from lightning surges.
• Data Line Protection: Protecting data lines and network interfaces from voltage transients.
• Security Systems: Protecting security system interfaces from voltage surges.
• Industrial Equipment: Protecting sensitive electronic components in industrial control systems.
• Central Office Equipment: Protecting equipment in central office telecom installations.

Features:

• Low Voltage Overshoot: Minimizes the voltage overshoot during a surge event, protecting sensitive components.
• High Surge Current Capability: Provides robust protection against high surge currents.
• Solid-State Protection: Offers reliable solid-state protection against overvoltage transients.
• Surface Mount Package: Suitable for automated assembly processes.
• RoHS Compliant: Meets environmental standards for lead-free components.

Benefits:

• Improved Equipment Reliability: Protects equipment from damage due to voltage transients.
• Reduced Downtime: Minimizes downtime due to equipment failure caused by surges.
• Easy Integration: Suitable for automated assembly processes.
• Robust Protection: Provides reliable protection against a wide range of surge events.
• Compact Design: Suitable for space-constrained applications due to its small footprint.

Specifications:

The P1800ECL has a breakover voltage (VBO) of 170V to 190V. The peak pulse current (IPP) is 100A. The holding current (IH) is typically 150mA. It comes in a DO-214AA (SMB) package. The operating temperature range is typically from -40°C to +125°C. The on-state voltage is low, minimizing power dissipation during a surge event.
