Procurement Notes

Verify the exact suffix codes against the manufacturer's latest datasheet to confirm voltage ratings and current capabilities. Ensure compliance with RoHS directives if required by the end application. Check for lead-free specifications and packaging details such as reel size or tube quantity before ordering. Confirm availability status as production lifecycles may change without notice.

Selection Notes

Select the KBP204 based on the required peak reverse voltage and average forward current ratings for the specific circuit design. Consider the operating temperature range and thermal management requirements of the enclosure. Compare physical dimensions and mounting style against the PCB layout constraints. Validate that the surge current rating exceeds the maximum expected inrush currents in the target application.
