1N4148WP

Single Diodes Overview

The Diotec Semiconductor 1N4148WP is a small signal switching diode in the Power-SOD-123 surface-mount package. It features a maximum repetitive peak reverse voltage (VRRM) of 100 V and a continuous average forward current (IFAV) of 150 mA. The device exhibits a very low junction capacitance of approximately 2 pF at 0 V bias and a maximum reverse recovery time (trr) of less than 4 ns. Forward voltage characteristics include a maximum of 0.715 V at 1 mA, 0.855 V at 10 mA, and 1.25 V at 150 mA. Leakage current is specified as less than 1 µA at 75 V reverse bias and 25°C.

Single Diodes Feature Summary

• Extremely fast switching capability with a reverse recovery time under 4 ns
• Low profile plastic Power-SOD-123 package design
• Minimal junction capacitance for high-frequency signal processing
• Low leakage current across standard operating temperatures

Single Diodes Applications

• High-speed switching circuits
• Signal processing applications
• Automotive electronics (suffix -AQ or -Q variants)

Single Diodes Procurement Notes

Verify the specific suffix to confirm compliance status. Standard versions are commercial/industrial grade. Suffixes -Q indicate AEC-Q101 compliance, while -AQ indicates AEC-Q101 qualification. Confirm RoHS exemption details if required by your manufacturing process. Ensure the ordering code matches the desired automotive or standard grade requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a compact surface-mount solution is required for high-speed signal switching. The Power-SOD-123 package offers higher power dissipation capabilities compared to standard SOD-123 variants. Consider the -AQ suffix if the application demands automotive-grade reliability standards. Verify that the 150 mA average current rating meets the circuit's continuous load requirements.

Single Diodes Part Context

This part belongs to the 1N4148 family of silicon switching diodes manufactured by Diotec Semiconductor. While the base 1N4148 typically utilizes DO-35 axial glass packaging, the WP variant specifically adapts the functionality into the Power-SOD-123 surface-mount form factor. This allows for automated assembly and space-constrained designs while maintaining the core electrical performance of the classic switching diode architecture.

Single Diodes Replacement Considerations

Direct physical replacements include other manufacturers' 1N4148 devices in the Power-SOD-123 outline. Cross-reference with Diotec's own alternative case outlines such as 1N4148W (SOD-123) or 1N4148WS (SOD-323F) if footprint constraints differ.
