K2300GAP

Overview

The Littelfuse K2300GAP is a high-voltage trigger diode (SIDAC) designed for breakover-triggered switching applications. It operates in the DO-15 through-hole package and supports an on-state RMS current of 1 A. The device features a nominal breakdown voltage of 230 V, with a maximum breakover voltage of 240 V and a minimum of 220 V. It withstands a rated repetitive off-state voltage of 190 V and maintains a holding current maximum of 150 mA. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional breakover triggering capability for symmetrical AC circuit protection
• High surge current handling with non-repetitive peak on-state current ratings up to 20 A
• Robust construction utilizing glass passivation for junction durability

Applications

• Overvoltage protection for sensitive semiconductor components
• Triggering circuits for silicon-controlled rectifiers (SCRs)
• Surge suppression in data ports and cable connectors

Procurement Notes

Verify the specific suffix 'GAP' against official Littelfuse documentation to confirm lead-free compliance and RoHS status. Confirm that the DO-15 axial package matches the target PCB layout requirements. Ensure the 230V nominal rating aligns with the system's transient voltage thresholds before finalizing procurement specifications.

Selection Notes

Select this component when bidirectional switching is required for AC line protection or SCR gate triggering. The 1A RMS rating suits moderate power applications, while the 240V max breakover voltage provides reliable activation above standard line peaks. Consider the DO-15 package size for available board space and thermal dissipation needs in the target assembly.

Part Context

This SIDAC belongs to Littelfuse's family of high-voltage trigger diodes, categorized under thyristors and circuit protection devices. These components are engineered to provide robust overvoltage protection by remaining non-conductive until a specific threshold is reached, at which point they switch rapidly to divert excess energy.

Replacement Considerations

The K2300GRP is a documented alternative from Littelfuse featuring similar electrical characteristics but housed in the DO-204AC package. Verify pin compatibility and mounting constraints when substituting between these package types.
