1N4150W-HE3-18

Single Diodes Overview

The 1N4150W-HE3-18 is a standard silicon 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 200 mA. The device exhibits a low forward voltage of 1 V at 200 mA and a rapid reverse recovery time of 4 ns. Reverse leakage current is specified as 100 nA at 50 V, with a capacitance of 2.5 pF at 0 V and 1 MHz. It operates within a junction temperature range of -55°C to 150°C and is housed in the SOD-123 surface-mount package.

Single Diodes Feature Summary

• High-speed switching capability with a 4 ns reverse recovery time for efficient signal processing.
• Automotive-grade reliability certified under AEC-Q101 standards for robust performance.
• Low power loss and high efficiency due to low forward voltage characteristics.
• Compact SOD-123 surface-mount package design suitable for space-constrained applications.

Single Diodes Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components.
• General-purpose signal switching and computer diode applications.
• High-frequency rectification in consumer electronics.
• Protection circuits in automotive open bus architectures.

Single Diodes Procurement Notes

This component has reached End-of-Life (EOL) status as per Product Change Notification Mult DEV EOL dated December 22, 2023. Verification of final availability from authorized distributors is essential before procurement planning. Designers should confirm if existing stock meets project requirements or initiate immediate transition strategies to approved replacement parts to ensure supply chain continuity.

Single Diodes Selection Notes

Select this component only if legacy compatibility with the 1N4150 family is required and the SOD-123 form factor is mandatory. Verify that the 50 V reverse voltage rating suffices for the specific circuit's peak inverse voltage conditions. Ensure the 200 mA current handling aligns with load demands. Given the EOL status, prioritize alternative sourcing or substitute part qualification immediately.

Single Diodes Part Context

The 1N4150W-HE3-18 belongs to the 1N4150 series of small-signal switching diodes produced by Vishay. It represents the surface-mount variant in the SOD-123 package, offering a modern alternative to traditional axial leaded packages like DO-35 while maintaining similar electrical characteristics. The HE3 suffix indicates a high-efficiency, halogen-free construction compliant with RoHS directives.

Single Diodes Replacement Considerations

Public confirmed substitute part numbers include 1N4150 from Microchip Technology. Evaluate pinout compatibility and electrical parameter equivalence when transitioning to alternative manufacturers to maintain circuit integrity.
