K1300S1URP

DIACs, SIDACs Overview

The K1300S1URP is a unidirectional SIDAC from the Kxxx0yU series, manufactured by Littelfuse. It functions as a silicon voltage-triggered switch housed in a DO-214AC (SMB) surface-mount package. Key electrical parameters include a breakover voltage range of 120V to 138V and a maximum breakover current of 10µA. The device supports an on-state RMS current of 1A with a peak output current of 16.7A. It operates within a temperature range of -40°C to +125°C TJ.

DIACs, SIDACs Feature Summary

DIACs, SIDACs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm RoHS compliance status via official documentation prior to integration. Ensure storage conditions maintain integrity against moisture sensitivity levels defined in the datasheet. Cross-reference ordering suffixes to confirm exact voltage binning and packaging specifications.

DIACs, SIDACs Selection Notes

Select this component when designing circuits requiring precise voltage threshold triggering for thyristor gates. The 120V to 138V breakover range suits low-voltage AC applications. Consider the 1A RMS current rating for load compatibility. Evaluate thermal performance within the specified -40°C to +125°C operating junction temperature range for environmental robustness.

DIACs, SIDACs Part Context

This part belongs to the Kxxx0yU SIDAC family, designed specifically for triggering applications in power electronics. Unlike standard diodes, it remains non-conductive until the breakover voltage is reached, then switches to a low-impedance state. The DO-214AC package provides a compact footprint suitable for modern PCB layouts requiring surface-mount technology integration.

DIACs, SIDACs Replacement Considerations

Compatible substitutes within the same Littelfuse series include K1050S1URP and K2300S1URP, which offer different breakover voltage ratings. Verify that alternative part numbers match the required trigger voltage and current handling capabilities for the specific application circuit.
