Single Diodes Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm the tape and reel packaging configuration. Ensure the part number matches the exact voltage and current ratings required for the target circuit design. Cross-reference the manufacturer's datasheet for any updates on environmental compliance or pinout definitions before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a general-purpose silicon switching diode with low capacitance and fast recovery is required. Compare the 75V reverse voltage rating against the circuit's peak inverse voltage requirements. Consider the 200mA current handling capability relative to the load conditions. Verify that the axial leaded package fits the available board space and mounting constraints.

Single Diodes Part Context

This part belongs to the standard 1N44xx series of small-signal switching diodes produced by Microchip Technology. These components are widely used in digital electronics for clamping, protection, and signal routing. The TR suffix indicates a specific bulk packaging method intended for surface mount or automated through-hole insertion processes.

Single Diodes Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements must match the 75V PIV, 200mA IF, and DO-35 package dimensions.
