K0900GRP

DIACs, SIDACs Overview

The Littelfuse K0900GRP is a high-voltage trigger diode, classified as a SIDAC within the thyristor product category. It operates in the through-hole DO-15 package and belongs to the Kxxxzy series. The device features a rated repetitive off-state voltage (VDRM) of 70 V with an operating temperature range from -40°C to +85°C. Electrical characteristics include a breakover voltage (VBO) ranging from 79 V to 97 V and a maximum breakover current (IBO) of 10 µA. The component supports an RMS on-state current (It RMS) of 1 A and a non-repetitive on-state current of up to 20 A. It exhibits a holding current (Ih) maximum of 150 mA, an on-state voltage of 1.5 V, and a leakage current of 5 µA at VDRM.

DIACs, SIDACs Feature Summary

DIACs, SIDACs Applications

• Triggering silicon-controlled rectifiers (SCRs) and triacs
• Overvoltage protection circuits requiring specific breakdown thresholds
• Pulse generation and timing circuits

DIACs, SIDACs Procurement Notes

Verify the exact suffix 'GRP' against official Littelfuse documentation to confirm packaging or tape-and-reel specifications differ from standard bulk units. Ensure RoHS compliance status is confirmed via the manufacturer's latest datasheet before integration into regulated assemblies.

DIACs, SIDACs Selection Notes

Select this component when a symmetrical bidirectional trigger device with a 70 V rating is required. Confirm that the 79 V to 97 V breakover voltage range aligns with the target circuit's sensitivity. Verify that the DO-15 package dimensions fit the available PCB space and that the 1 A RMS current rating meets the load requirements.

DIACs, SIDACs Part Context

The K0900GRP belongs to the Littelfuse K-series of high-voltage trigger diodes. These devices are designed for reliable switching in high-voltage environments. The part number indicates a specific variant within the broader Kxxxzy family, sharing core electrical characteristics with other members while potentially differing in packaging or testing criteria.

DIACs, SIDACs Replacement Considerations

Consult Littelfuse cross-reference guides for direct equivalents. Generic replacements must match the 70 V VDRM, 79-97 V VBO range, and DO-15 package. Verify thermal and current ratings before substitution.
