K2000S1URP

DIACs, SIDACs Overview

The K2000S1URP is a high-voltage trigger diode (SIDAC) manufactured by Littelfuse under the Teccor brand. It is designed for surface-mount installation in the DO-214AC (SMB) package. Key electrical parameters include a breakover voltage (VBO) of 220 V and a maximum breakover current (IBO) of 10 uA. The device supports an RMS on-state current (It RMS) of 1 A and a non-repetitive on-state current of 16.7 A or 20 A. It operates within a temperature range of -40 C to +150 C, with a holding current (Ih) maximum of 80 mA and an on-state voltage of 1.2 V.

DIACs, SIDACs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before procurement. Confirm that the DO-214AC package dimensions align with your PCB footprint requirements. Ensure that the supply chain source is authorized to guarantee component authenticity and traceability.

DIACs, SIDACs Selection Notes

Select this component when a stable breakover voltage around 220 V is required for triggering applications. Consider the 1 A RMS current rating for load handling capabilities. Verify that the operating temperature range meets the environmental conditions of the target application. Compare against other SIDACs if different voltage thresholds or current ratings are needed.

DIACs, SIDACs Part Context

This part belongs to the Kxxx0yU series of high-voltage trigger diodes from Littelfuse. These devices are categorized as thyristors and are marketed under the Teccor trademark. The series is engineered for reliable switching in high-voltage scenarios, providing a cost-effective solution for protecting sensitive electronics from transient overvoltages.

DIACs, SIDACs Replacement Considerations

Check for direct substitutes within the same Littelfuse family, such as variants with different breakover voltages like the K2200S1URP or K2300S1URP. Ensure any replacement maintains the DO-214AC package and similar electrical characteristics to avoid redesigning the PCB layout.
