1N4151

Single Diodes Overview

The onsemi 1N4151 is a silicon signal diode housed in the DO-35 axial leaded package. It features a maximum average forward rectified current of 0.15 A and a maximum repetitive peak reverse voltage of 75 V. The device operates within a temperature range of -65 °C to 200 °C, with a maximum power dissipation of 0.5 W. Its maximum reverse recovery time is specified at 0.004 µs, indicating fast switching capabilities suitable for high-speed applications.

Single Diodes Feature Summary

• Fast switching performance with minimal reverse recovery time
• High reliability construction using silicon epitaxial planar technology
• Hermetically sealed glass package for environmental protection

Single Diodes Applications

• General purpose signal rectification
• High speed switching circuits
• Clamping and protection applications

Single Diodes Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce this standard part number. Confirm compliance requirements such as RoHS status, as historical data indicates non-compliant variants exist. Ensure the package type matches the DO-35 specification and check for any suffixes that may indicate tape and reel packaging versus bulk quantities.

Single Diodes Selection Notes

Select this component for applications requiring a robust, hermetically sealed silicon diode with fast switching characteristics. The 75 V reverse voltage rating limits its use to low-voltage signal processing rather than power conversion. Consider the thermal management requirements given the 0.5 W power dissipation limit and the operating temperature range up to 200 °C.

Single Diodes Part Context

The 1N4151 belongs to the family of general-purpose fast switching diodes, often compared to the 1N914. It shares similar electrical characteristics but is distinguished by its specific manufacturing standards and package variations across different suppliers. This part is widely used in legacy and modern electronic designs requiring reliable signal handling.

Single Diodes Replacement Considerations

Direct substitutes include the 1N914 and 1N4148, which offer comparable electrical specifications. Verify pinout compatibility and package dimensions before substitution. Some manufacturers offer surface mount equivalents like the LL4151 for space-constrained designs.
