1N4137

Single Diodes Overview

The Microchip Technology 1N4137 is a silicon power rectifier diode designed for general-purpose switching applications. It features a single diode configuration housed in a DO-35 axial leaded package. The component supports a maximum repetitive reverse voltage of 100V and an average forward rectified current of 150mA. These electrical characteristics define its operational limits for signal processing and low-power rectification tasks within electronic circuits.

Single Diodes Feature Summary

• Constructed from silicon material for reliable semiconductor performance
• Utilizes a single diode configuration for standard circuit integration
• Encapsulated in a DO-35 axial leaded package for through-hole mounting

Single Diodes Applications

• General-purpose signal switching
• Low-power rectification circuits
• Voltage clamping applications

Single Diodes Procurement Notes

Verify the manufacturer designation on the datasheet, as sources list both Microsemi Corporation and Microchip Technology for this part number. Confirm the package type is DO-35 and that the device is classified as a silicon power rectifier rather than a Zener diode, despite conflicting descriptions in some third-party listings. Ensure the electrical ratings match the 100V reverse voltage and 150mA forward current specifications before procurement.

Single Diodes Selection Notes

Select this component when a small-signal silicon rectifier with axial leads is required. The DO-35 package suits through-hole PCB designs. Verify compatibility with the 100V peak inverse voltage requirement. This part is suitable for general switching duties but may not be appropriate for high-current or high-voltage power supply applications exceeding its specified ratings.

Single Diodes Part Context

The 1N4137 belongs to the family of silicon junction rectifiers commonly used in consumer electronics and industrial control systems. While often associated with switching diodes like the 1N4148, official documentation identifies this specific part as a silicon power rectifier. It serves as a fundamental discrete semiconductor component for managing current flow in low-power analog and digital circuits.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing with similar DO-35 silicon rectifiers requires independent verification against specific application requirements.
