K2300G

Overview

The Littelfuse K2300G is a silicon bilateral voltage-triggered switch (SIDAC) from the Kxxxzy series, designed for AC circuit protection. It features a breakover voltage range of 220V to 240V and a repetitive peak off-state voltage of 190V. The device supports an on-state RMS current of 1A at 50/60Hz with a junction temperature below 125°C. Key electrical parameters include a peak on-state voltage of 1.5V, a dynamic holding current between 10mA and 150mA, and a peak non-repetitive surge current of 20A for a single cycle at 60Hz. It operates within a junction temperature range of -40°C to 125°C and utilizes a DO-15 package.

Feature Summary

• Silicon bilateral voltage triggered switch with glass-passivated junctions for ruggedness
• Negative resistance region switching to low on-state voltage upon breakover
• RoHS compliant construction suitable for harsh environments

Applications

• High voltage power supplies
• Natural gas igniters
• High-pressure Sodium lamps
• Xenon flash ignition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the package type and packaging mode. The 'G' suffix indicates a DO-15 package available in bulk or reel pack formats. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the breakover voltage specifications align with the target circuit design before procurement.

Selection Notes

Select the K2300G when a breakover voltage between 220V and 240V is required for AC circuit protection. Consider the 1A RMS current rating and 190V blocking voltage for appropriate load handling. Evaluate the thermal resistance and maximum allowable case temperature curves to ensure adequate heat dissipation in the final application environment.

Part Context

The K2300G belongs to the Kxxxzy Series of Standard Bidirectional SIDACs manufactured by Littelfuse. This series includes various voltage ratings ranging from 79V to 330V. The component serves as a solid-state alternative to mechanical switches for triggering high-voltage circuits, offering reliable performance in overcurrent and transient protection scenarios.

Replacement Considerations

Compatible substitutes within the same family include K2200G and K2400G, which offer similar characteristics with slightly different breakover voltage ranges. Verify that any replacement part maintains the required DO-15 package dimensions and electrical ratings for the specific application.
