Applications

• Silicon-Controlled Rectifier (SCR) gate triggering
• AC power control circuit protection
• Overvoltage protection devices

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm package marking matches official datasheet specifications. Request batch traceability documentation and RoHS compliance certificates prior to procurement. Ensure storage conditions adhere to manufacturer guidelines to prevent moisture sensitivity damage during assembly.

Selection Notes

Select this component when bidirectional triggering is required for SCRs in AC environments. The SMA package suits space-constrained designs. Verify that the 142V to 157V breakover range aligns with system voltage requirements. Consider thermal management and peak current handling capabilities relative to the specific application load.

Part Context

This part belongs to the SIDAC family of bidirectional trigger diodes from Diodes Incorporated. It complements standard DIACs by offering higher voltage ratings and improved stability for industrial-grade applications. The -13 suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Consult official substitution guides for equivalent SIDACs with matching voltage thresholds and package dimensions. Verify electrical parameters such as breakover voltage tolerance and peak current ratings before cross-referencing alternative manufacturers.
