1N4148WS

Single Diodes Overview

The 1N4148WS is a silicon epitaxial planar small signal switching diode manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features a peak reverse voltage of 75 V and a maximum forward current of 150 mA. The device exhibits a fast reverse recovery time of 4 ns and a low junction capacitance of 4 pF. It operates within a temperature range of -55°C to +150°C and is housed in an SOD-323 surface-mount package.

Single Diodes Feature Summary

• Fast switching capability with 4 ns reverse recovery time
• Compact SOD-323 surface-mount packaging for space-constrained designs
• High thermal stability supporting operation up to 150°C

Single Diodes Applications

• High-speed digital signal processing circuits
• General-purpose rectification in consumer electronics
• Clamping and protection in communication interfaces

Single Diodes Procurement Notes

Verify the manufacturer designation on the component marking against Shenzhen Slkormicro Semicon Co., Ltd. specifications. Confirm RoHS compliance status and specific tape-and-reel quantities required for automated assembly processes prior to ordering.

Single Diodes Selection Notes

Select this component when a compact surface-mount solution is required for high-frequency switching applications. Ensure the 75 V reverse voltage rating exceeds the circuit's peak inverse voltage requirements and that the 150 mA forward current capacity meets load demands.

Single Diodes Part Context

This part belongs to the standard small-signal diode family, serving as a surface-mount alternative to through-hole variants like the DO-35 packaged 1N4148. It maintains similar electrical characteristics while offering improved PCB density and automated placement compatibility for modern manufacturing lines.

Single Diodes Replacement Considerations

Compatible substitutes include Vishay 1N4148WS-G3-08 and onsemi 1N4148WS. Verify pinout compatibility and thermal resistance values when transitioning between manufacturers to ensure equivalent performance in the final assembly.
