1N5258

Single Zener Diodes Overview

The SMC Diode Solutions 1N5258 is a unidirectional silicon voltage regulator diode designed for general-purpose applications. It operates within the DO-35 axial leaded glass package, providing a nominal Zener voltage of 36 V with a standard tolerance of 20%. The device is rated for a maximum power dissipation of 0.48 W at 25°C ambient temperature, extending to 0.5 W at 75°C. It supports a junction temperature up to 175°C and functions reliably across a storage temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass axial-leaded DO-35 case for environmental protection
• Provides stable voltage regulation through a planar Zener design
• Features a unidirectional configuration for single-polarity circuit protection

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in low-power electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source when sourcing this component, as the 1N5258 designation is widely used by multiple semiconductor producers including Microsemi and LRC. Confirm that the received unit matches the required electrical characteristics and physical dimensions. Ensure the packaging type aligns with your assembly requirements, as variations exist between bulk and reel formats depending on the supplier.

Single Zener Diodes Selection Notes

Select this component when a 36 V regulation point is required in a compact axial package. Consider the 20% standard tolerance unless tighter specifications are needed, which may require alternative suffixes. Evaluate the thermal environment to ensure the 0.48 W rating is sufficient for the expected operating conditions without excessive derating.

Single Zener Diodes Part Context

This part belongs to the broader family of 0.5 W silicon Zener diodes, commonly referenced under the 1N5221 through 1N5281 series. These components are standardized JEDEC registered devices widely adopted in industrial and commercial electronics. The 1N5258 specifically targets the mid-range voltage segment of this extensive lineup.
