• Glass-passivated junctions for enhanced stability

Triacs Applications

• High-voltage lamp ignitors
• Natural gas and oil ignitors
• Xenon ignitors
• Fluorescent lighting ignitors
• HID lighting ignitors

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout, packaging style, and compliance status. Ensure the selected variant matches the required thermal and electrical specifications for the target circuit design before procurement.

Triacs Selection Notes

Select this component when a logic-level TRIAC is required for high-voltage AC control applications. Confirm that the 600 V blocking voltage and 4 A current rating align with the load requirements. Verify compatibility with the TO-202AB package for the intended PCB layout or heatsinking solution.

Triacs Part Context

This part belongs to the Littelfuse Sensitive Triacs family, designed for AC circuit orientation. It serves as a silicon bilateral voltage-triggered switch with high surge current capability, functioning similarly to standard diacs but with greater power-handling capabilities for industrial and consumer electronics.

Triacs Replacement Considerations

Cross-reference with other sensitive triacs from manufacturers such as STMicroelectronics or Teccor Electronics. Ensure equivalent ratings for V(DRM), I(T)RMS, and gate trigger characteristics are met before substitution.
