Single Diodes Procurement Notes

Verify the specific ordering suffix RHG corresponds to the green compound packing code as defined in the manufacturer's documentation. Confirm that the SOD-123 package dimensions align with the suggested pad layout provided in the datasheet. Ensure compliance requirements such as RoHS and halogen-free status match the project specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a small signal switching diode with low reverse recovery time is required for surface mount assembly. The SOD-123 package offers a compact footprint suitable for space-constrained designs. Consider the 100V reverse voltage rating and 250mA average forward current limits to ensure adequate headroom for the intended circuit operating conditions.

Single Diodes Part Context

This part belongs to the 1N4148 series of small signal switching diodes produced by Taiwan Semiconductor. The standard 1N4148 typically utilizes a DO-35 axial leaded package, whereas the 1N4148W variant adapts the same electrical performance profile into a modern surface mount form factor. This evolution supports automated assembly processes while maintaining the high-speed switching characteristics associated with the legacy designation.

Single Diodes Replacement Considerations

Direct replacements must maintain the SOD-123 package and equivalent electrical ratings. Verify that substitute components offer comparable reverse recovery times and forward voltage characteristics to ensure circuit performance parity.
