Scrs Procurement Notes

Verify the specific suffix '112' to confirm the manufacturer packaging configuration and compliance status. Ensure the component matches the required 400V rating and TO-92-3 package dimensions for your PCB layout. Cross-reference the datasheet revision date to confirm technical specifications align with your design requirements before finalizing procurement.

Scrs Selection Notes

Select this component when a sensitive gate SCR is required for low-power triggering environments. The 400V rating suits general-purpose AC control applications. Consider the TO-92-3 through-hole package for standard prototyping or cost-sensitive designs. Verify that the 800mA RMS current meets the load requirements and that the 50uA gate trigger current is compatible with the driving logic.

Scrs Part Context

This part belongs to the BT169 series of sensitive gate SCRs from WeEn Semiconductors. These devices are designed for applications requiring reliable switching with minimal gate drive power. The series typically includes variants with different voltage ratings, such as the BT169H for higher voltage needs. The BT169D specifically targets the 400V market segment.

Scrs Replacement Considerations

Check for direct equivalents like the BT169D from other manufacturers ensuring identical pinout and electrical characteristics. Verify that any substitute maintains the sensitive gate requirement and TO-92-3 package compatibility.
