K3002GRP

Overview

The K3002GRP is a SIDAC thyristor manufactured by Littelfuse Inc., designed for high-voltage triggering applications. It operates within the Kxxxzy series and features a DO-15 leaded package. The device specifies a breakover voltage (VBO) range of 270 V to 330 V, ensuring reliable switching at elevated potentials. The maximum breakover current (IBO) is rated at 10 uA, facilitating low-power trigger initiation. This component serves as a critical element in circuit protection schemes requiring precise voltage threshold activation.

Feature Summary

• High-voltage triggering capability with defined breakover thresholds
• Low breakover current for sensitive trigger initiation
• Leaded DO-15 package for robust PCB mounting

Applications

• Triggering silicon-controlled rectifiers (SCRs)
• Triac gate drive circuits
• Overvoltage protection systems

Procurement Notes

Verify the specific ordering suffix 'GRP' against the manufacturer's latest datasheet to confirm package type and compliance status. Ensure the required breakover voltage range aligns with the 270 V to 330 V specification for your circuit design. Cross-reference the DO-15 package dimensions with your board layout constraints before finalizing procurement.

Selection Notes

Select this component when a stable, high-voltage trigger source is required for SCRs or Triacs. The 270 V to 330 V breakover range suits applications involving mains voltage isolation or high-potential signaling. Consider the DO-15 package size if space allows for leaded components, as it offers mechanical stability compared to surface-mount alternatives.

Part Context

This part belongs to the Kxxxzy series of SIDACs from Littelfuse Inc., specialized for triggering other thyristors. Unlike DIACs which are bidirectional, SIDACs offer higher voltage handling capabilities suitable for industrial and power control environments. The K3002GRP specifically targets applications needing reliable switching at voltages exceeding standard logic levels.

Replacement Considerations

Check for direct substitutes within the Kxxxzy series that match the 270 V to 330 V VBO range and 10 uA IBO limit. Ensure any replacement maintains the DO-15 package form factor for compatibility with existing footprints.
