K1100GRP

Overview

The Littelfuse K1100GRP is a high-voltage trigger diode, classified as a SIDAC within the thyristor family. It utilizes a DO-15 through-hole package for robust circuit integration. The device features a breakover voltage (VBO) range of 104 V to 118 V and a rated repetitive off-state voltage (VDRM) of 90 V. It supports an RMS on-state current of 1 A with non-repetitive peak currents up to 20 A. Operating temperatures span from -40°C to +85°C, ensuring reliability in demanding environments.

Feature Summary

• Bidirectional switching capability for AC circuit protection applications
• High surge current handling capacity for transient suppression
• Robust through-hole construction for secure PCB mounting

Applications

• Overvoltage protection for sensitive electronic circuits
• Triggering elements for silicon-controlled rectifiers (SCRs)
• Surge protection devices in industrial control systems

Procurement Notes

Verify the specific suffix 'GRP' against official Littelfuse documentation to confirm exact binning or tolerance variations compared to standard K1100 variants. Ensure component authenticity by sourcing from authorized distributors only. Cross-reference datasheet revisions to confirm compliance with current RoHS and REACH standards before final procurement decisions.

Selection Notes

Select this component when a bidirectional trigger device with a 100V nominal breakover voltage is required. The DO-15 package suits applications needing higher mechanical stability than surface-mount options. Verify that the 1 A RMS current rating aligns with the load requirements and that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the Kxxxzy series of high-voltage trigger diodes manufactured by Littelfuse. These components are designed specifically for triggering SCRs and triacs in phase control and protection circuits. The K1100 variant represents a standard 100V class device within this broader product line.

Replacement Considerations

Direct substitutes include other 100V SIDACs in DO-15 packages such as the Bourns SLC100A or STMicroelectronics STK100B. Verify pinout compatibility and thermal characteristics when replacing. Ensure the alternative device meets the same VBO and I_T(RMS) specifications.
