K2000GURP

DIACs, SIDACs Overview

The K2000GURP is a silicon unilateral voltage-triggered switch (SIDAC) manufactured by Littelfuse Inc. It operates within the Kxxx0yU series and is housed in a DO-15 axial leaded package. The device features a breakover voltage range of 190 to 210V and supports an on-state RMS current of 1A. It has a maximum holding current of 80mA and functions as a two-terminal AC switching component. The unit is rated for a maximum operating temperature of +125°C and utilizes through-hole mounting for integration into circuit protection designs.

DIACs, SIDACs Procurement Notes

Verify the specific manufacturer designation, noting that Littelfuse acquired Hamlin. Confirm the package type remains DO-15 and the electrical parameters match the 190-210V breakover range. Ensure the suffix GURP corresponds to the required tape-and-reel or bulk packaging configuration if applicable, and validate the maximum operating temperature rating against the latest official datasheet.

DIACs, SIDACs Selection Notes

Select this component when a high-voltage trigger device with a 1A current capacity is required. The DO-15 package suits through-hole PCB layouts. Consider the 190-210V breakover threshold for triggering downstream thyristors. Verify that the 80mA holding current meets the circuit's minimum load requirements to ensure reliable latching behavior during operation.

DIACs, SIDACs Part Context

This part belongs to the Kxxx0yU SIDAC family from Littelfuse. These devices are designed as voltage-triggered switches for protecting sensitive electronics. The K2000GURP specifically targets applications requiring precise voltage breakdown characteristics in a robust axial leaded form factor, distinguishing it from bidirectional DIACs.

DIACs, SIDACs Replacement Considerations
