Procurement Notes

Verify the specific manufacturer datasheet to confirm exact pinout orientation and thermal resistance values. Ensure the selected packaging format matches the intended automated assembly process requirements. Cross-reference the RoHS certification status with current regulatory standards before finalizing procurement specifications.

Selection Notes

Select this component when space constraints necessitate a 1005 footprint while maintaining a 45 V reverse voltage rating. Consider the 200 mA current limit and 450 mV forward voltage characteristics for efficiency calculations. Evaluate the 125 °C junction temperature limit against the expected ambient operating conditions of the target application environment.
