The K1300G is a SIDACtor protection thyristor manufactured by Littelfuse. It's designed to protect sensitive telecommunications equipment from damaging voltage surges, particularly those caused by lightning and power faults. This device is a solid-state switching device that rapidly switches to a low-voltage on-state when the voltage across it exceeds its breakover voltage, thereby diverting the surge current away from the protected equipment.

Applications

• Central Office Equipment
• Access Network Equipment (e.g., DSL modems)
• Customer Premises Equipment (e.g., telephone handsets, fax machines)
• General Telecom Linecard Protection

Features

• Low On-State Voltage: Minimizes stress on protected circuitry during surge events.
• High Surge Current Capability: Designed to withstand high surge currents as defined by industry standards.
• Low Capacitance: Minimizes signal degradation in high-bandwidth telecommunications applications.
• RoHS Compliant: Environmentally friendly, complying with Restriction of Hazardous Substances directives.
• Breakover Voltage: 130V
• Peak Pulse Current: 75A

Benefits

• Enhanced Equipment Reliability: Protects sensitive equipment from voltage surges, extending its operational life.
• Reduced Downtime: Prevents equipment damage and associated downtime due to surge events.
• Compliance with Regulatory Standards: Helps equipment manufacturers meet regulatory requirements for surge protection.
• Cost-Effective Protection: Provides a cost-effective solution for protecting valuable telecommunications equipment.

The K1300G features a DO-214AA (SMB) package, suitable for surface mounting. Its fast response time and robust construction make it a reliable choice for surge protection in a variety of telecommunications applications. Key technical specifications include a breakover voltage (VBO) of 130V and a peak pulse current (IPP) capability of 75A. It's also designed to operate over a wide temperature range.
