1N4148WL

Single Diodes Overview

The EVVO 1N4148WL is a silicon epitaxial planar switching diode housed in an SOD-123FL surface-mount package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous forward current rating of 150 mA. The device exhibits a typical reverse recovery time of 8 ns and a junction capacitance of 5 pF at 25 °C. Absolute maximum ratings include a total power dissipation of 400 mW and an operating temperature range from -55 °C to +150 °C.

Single Diodes Feature Summary

• Designed for automated placement in surface mount processes

Single Diodes Applications

• High-speed switching circuits
• LED lighting driver protection
• General purpose signal rectification

Single Diodes Procurement Notes

Verify the manufacturer designation, as EVVO is not a standard industry identifier for this part number. Confirm the specific datasheet version matches the required electrical tolerances. Ensure the SOD-123FL footprint dimensions align with the PCB layout. Check for RoHS compliance documentation if required by regional regulations. Validate that the 150 mA current rating meets the application's thermal constraints.

Single Diodes Selection Notes

Select this component when a small surface-mount switching diode with fast recovery is required. The SOD-123FL package offers space efficiency compared to axial leads. Consider the 150 mA continuous current limit and 400 mW power dissipation for thermal management. The 8 ns reverse recovery time makes it suitable for frequencies where slower diodes would fail. Verify compatibility with automated assembly equipment.

Single Diodes Part Context

The 1N4148WL belongs to the family of small-signal switching diodes derived from the classic 1N4148 specification. While traditional versions use DO-35 axial packages, the WL suffix denotes a surface-mount variant in the SOD-123FL case outline. This evolution allows for higher density PCB mounting while maintaining similar switching performance profiles found in through-hole equivalents.

Single Diodes Replacement Considerations

Standard 1N4148 variants in SOD-123 or SOD-323 packages may serve as functional substitutes if pinout and electrical ratings are compatible. LL4148 devices offer comparable performance in MiniMELF cases. Verify that replacement parts meet the 100 V reverse voltage and 150 mA forward current requirements.
