K2000GHRP

Overview

The Littelfuse K2000GHRP is a bidirectional trigger diode, classified as a SIDAC, designed for triggering and overvoltage protection functions. It features a breakover voltage range of 190 to 215 V with a maximum of 215 V. The device supports a peak current rating of 1 A and operates within a temperature range of -40°C to +125°C. Packaged in a DO-15 (DO-204AC) axial leaded plastic housing, it ensures compliance with RoHS standards.

Feature Summary

• Bidirectional triggering capability for symmetric circuit applications
• Robust overvoltage protection mechanism via controlled breakover
• High thermal stability suitable for demanding industrial environments

Applications

• Triggering silicon-controlled rectifiers (SCRs) and triacs
• Overvoltage protection circuits in power supplies
• Gate drive circuits for thyristor-based systems

Procurement Notes

Verify the specific ordering suffix GHRP against official Littelfuse documentation to confirm package type and compliance status. Ensure the component matches the required breakover voltage tolerance for the target application. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

Selection Notes

Select this component when a bidirectional trigger device with a 190–215 V breakover threshold is required. The DO-15 package provides adequate mechanical strength for through-hole mounting. Consider the 1 A current rating to ensure the device can handle the gate charge requirements of the downstream thyristor without damage during triggering events.

Part Context

The K2000GHRP belongs to the K2000 series of SIDACs manufactured by Littelfuse Inc. This series is engineered for reliable gate triggering and surge protection. The device utilizes non-punch-through technology to ensure stable switching characteristics and consistent performance across the specified operating temperature range.

Replacement Considerations

The K2000GRP is a related part within the same family offering similar electrical characteristics. Verify pinout compatibility and exact voltage tolerances when substituting. Ensure any replacement maintains the DO-15 package form factor for direct board integration.
