1N4150-1

Single Diodes Overview

The 1N4150-1 is a small signal switching diode manufactured by Microchip Technology, designed for through-hole mounting in DO-35-2 packages. It features a peak reverse voltage of 50 V and supports a maximum forward current of 200 mA with a surge current capacity of 4 A. The device exhibits a fast recovery time of 4 ns and a low forward voltage drop of 1 V at rated current. Reverse leakage current is specified at 100 nA. Operating temperatures range from -65 C to +175 C, ensuring reliability in demanding environments.

Single Diodes Feature Summary

• Fast switching capability with 4 ns recovery time suitable for high-speed digital applications
• High thermal stability operating up to +175 C junction temperature
• Robust surge current handling up to 4 A for transient protection

Single Diodes Applications

• Computer logic circuits requiring fast switching
• Signal clipping and clamping applications
• General purpose rectification in low power systems

Single Diodes Procurement Notes

Verify the specific suffix '-1' against the official Microchip datasheet to confirm screening levels or package variations. Confirm RoHS status as the provided data indicates non-compliance. Check lead times due to potential long production cycles. Ensure the DO-35-2 package matches your PCB footprint requirements before ordering.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating and 200 mA continuous forward current are required. The 4 ns recovery time makes it suitable for faster applications compared to standard rectifiers. Consider the TO-92 or DO-35 package constraints. Verify that the 100 nA reverse leakage meets your circuit's noise immunity requirements.

Single Diodes Part Context

This part belongs to Microchip's legacy small-signal diode portfolio, often used in industrial and military-grade electronics. The 1N4150 series is historically significant for its reliability in discrete logic and signal processing. It serves as a robust alternative to modern surface-mount equivalents where through-hole durability is preferred.

Single Diodes Replacement Considerations

Check for direct cross-references such as 1N914 or 1N4148 if voltage ratings allow. Verify pinout compatibility for DO-35 packages. Ensure replacement parts meet the same 175 C operating temperature requirement.
