1N5119

Single Zener Diodes Overview

The Microchip Technology 1N5119 is a single axial-lead Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 40V with a tolerance of ±5%. The component operates in a through-hole E package (DO-201) and supports a power dissipation rating of 5W. Key electrical parameters include a Zener impedance of 14 Ohms, a maximum reverse leakage current of 3 uA at rated voltage, and a test current of 115 mA. The device functions within an operating temperature range from -65°C to +175°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 40V level
• Supports high power dissipation up to 5W for robust circuit protection
• Utilizes a standard through-hole axial lead package for easy integration

Single Zener Diodes Applications

• Voltage regulation in electronic circuits
• Overvoltage protection stages
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix, such as /TR, if tape-and-reel packaging is required instead of bulk. Confirm RoHS compliance status as it may vary by production batch or region. Ensure the selected variant matches the required axial lead form factor and power rating for the target application environment.

Single Zener Diodes Selection Notes

Select this component when a 40V regulation point is needed with significant power handling capabilities. The 5W rating allows use in higher current scenarios compared to lower-power equivalents. Verify that the thermal management design accommodates the full 5W dissipation under worst-case conditions to maintain reliability within the specified temperature range.

Single Zener Diodes Part Context

This part belongs to the standard 1N series of Zener diodes manufactured by Microchip Technology. It is categorized under discrete semiconductors and specifically within the diodes and rectifiers subcategory. The 1N5119 serves as a rugged solution for industrial and commercial electronics requiring reliable voltage clamping.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 40V Zener voltage, 5W power rating, and DO-201 axial package. Check datasheets for equivalent parts from other manufacturers to ensure compatible Zener impedance and leakage current specifications.
