Single Diodes Procurement Notes

Verify the specific suffix TPS01 against official MCC documentation to confirm exact packing or marking variations. Standard ordering information indicates Tape & Reel options with quantities of 3K or 10K pcs per reel. Ensure sourcing through authorized distributors to guarantee genuine parts with full traceability and compliance with quality standards.

Single Diodes Selection Notes

Select this component for designs requiring compact SMD solutions with rapid switching performance. The SOD-123 footprint offers space efficiency compared to axial packages. Consider the 400mW power dissipation limit and thermal resistance when determining heat management requirements in dense PCB layouts.

Single Diodes Part Context

This part belongs to the 1N4148 family of small-signal switching diodes. While standard variants often utilize DO-35 axial packages, this specific model employs the SOD-123 surface-mount form factor. It maintains the core electrical specifications of the legacy 1N4148 while adapting to modern automated assembly processes.

Single Diodes Replacement Considerations

Direct replacements include other SOD-123 packaged 1N4148 variants such as the 1N4148W-TP or 1N4148WHE3-TP from MCC. Cross-brand equivalents like the BAS70 or similar high-speed switching diodes in SOD-123 may be considered if pinout and electrical ratings align.
