1N4151WS-E3-08

Single Diodes Overview

The 1N4151WS-E3-08 is a small signal fast switching diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 50 V and an average rectified forward current (Io) of 150 mA. The device utilizes the SOD-323 surface mount package. Key electrical parameters include a reverse recovery time (trr) of 4 ns, a maximum reverse leakage current of 50 nA at 50 V, and a forward voltage of 1 V at 50 mA. The junction operating temperature range spans from -55°C to +150°C.

• Fast switching capability with a 4 ns reverse recovery time for high-speed signal processing
• Compact SOD-323 surface mount package design suitable for space-constrained PCB layouts
• Wide thermal operating range supporting environments from -55°C to +150°C

Single Diodes Applications

• High-speed signal switching circuits
• General purpose rectification in low-power electronics
• Clamping and protection applications in consumer devices

Single Diodes Procurement Notes

Verify the specific suffix E3-08 to confirm RoHS compliance and lead-free status as defined by Vishay. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, to align with assembly line requirements. Cross-reference the manufacturer datasheet for any recent product change notices that may affect pinout or material composition before finalizing procurement.

Single Diodes Selection Notes

Select this component when a compact SOD-323 footprint is required alongside fast switching performance. The 50 V rating makes it suitable for low-voltage logic interfaces. Compare the 4 ns trr against application timing constraints. Verify that the 150 mA current limit meets the circuit's peak load demands without exceeding thermal dissipation limits within the specified temperature range.

Single Diodes Part Context

This component belongs to the 1N4151 family of small signal diodes, adapted for surface mount technology. While traditional 1N4151 variants use axial leads, the WS variant specifically denotes the SOD-323 package. This evolution allows for automated placement and reduced board space usage while maintaining similar electrical characteristics to through-hole equivalents.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4151W-E3-08, which shares identical electrical specifications but utilizes the SOD-123 package. Designers must verify mechanical fitment differences between SOD-123 and SOD-323 footprints. Other generic fast-switching diodes may require re-evaluation of reverse voltage and current ratings.
