DIACs, SIDACs Procurement Notes

Verify the specific datasheet for the K1500GRP to confirm exact breakover voltage tolerances and RoHS compliance status before integration. Confirm that the TO-92 through-hole mounting style aligns with the target PCB layout requirements. Ensure the 1 A current rating meets the load specifications of the intended application circuit.

DIACs, SIDACs Selection Notes

Select this component when a bidirectional voltage-triggered switch is required for AC circuits. The TO-92 package suits through-hole assembly processes. Verify that the operating environment does not exceed the thermal limits defined in the official specification sheet. Compare against similar SIDACs if specific voltage thresholds differ from the standard range.

DIACs, SIDACs Part Context

This part belongs to the Littelfuse Teccor brand SIDAC family, specifically the K1500S series. These devices are silicon bilateral voltage-triggered switches that conduct after exceeding a breakover voltage. The K1500GRP shares characteristics with other variants like K1500S70AP, differing primarily in packaging or specific voltage ratings within the same functional class.

DIACs, SIDACs Replacement Considerations

Cross-reference with K1500S70AP or K1500S70RP for equivalent bidirectional SIDAC functionality. Verify pinout compatibility and package dimensions (TO-92) before substitution. Ensure the replacement part meets the same AC circuit orientation and current rating requirements.
