1N4151W-E3-18

Single Diodes Overview

The 1N4151W-E3-18 is a silicon small signal switching diode manufactured by Vishay General Semiconductor - Diodes Division. It features a surface-mount SOD-123 package with two leads. The device supports an average forward rectified current of 150 mA and a maximum repetitive peak reverse voltage of 75 V. Key electrical characteristics include a maximum reverse recovery time of 4 ns and a junction temperature range from -55°C to 150°C.

Single Diodes Feature Summary

• Fast switching capability with a maximum reverse recovery time of 4 ns
• High reliability construction using silicon epitaxial planar technology
• RoHS compliant manufacturing process without halogenated substances

Single Diodes Applications

• General purpose high-speed switching circuits
• Clamping and protection applications in electronic systems
• Pulse processing and logic interface circuits

Single Diodes Procurement Notes

Verify the specific suffix E3-18 against the manufacturer's official datasheet to confirm RoHS compliance and reel packaging specifications. Ensure the component matches the SOD-123 footprint requirements for your PCB design. Cross-reference the part number with Vishay's current production status to avoid obsolete stock issues during procurement.

Single Diodes Selection Notes

Select this component when a fast-switching silicon diode is required in a compact surface-mount form factor. The 150 mA current rating suits low-power signal applications. Consider the 75 V reverse voltage limit for circuit compatibility. Verify thermal management needs within the specified junction temperature range for reliable operation.

Single Diodes Part Context

This part belongs to the 1N4151 family of small signal switching diodes. It serves as the surface-mount equivalent to through-hole variants like the DO-35 packaged 1N4151. The W suffix indicates the SOD-123 package style, while E3 denotes environmental compliance. This series is widely used in consumer electronics and industrial control systems requiring compact switching solutions.

Single Diodes Replacement Considerations

The 1N4151W-E3-08 is a verified alternative from the same manufacturer offering identical electrical performance in a different tape-and-reel quantity configuration.
