1N5254B_T50R

Single Zener Diodes Overview

The onsemi 1N5254B_T50R is a silicon planar Zener diode designed for voltage regulation and reference applications. It features a nominal Zener voltage of 27 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at 25°C ambient temperature. It utilizes the DO-35 axial leaded glass package, providing isolation between the junction and the external environment. The component supports a wide operating temperature range from -65°C to +200°C junction temperature.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for stable voltage regulation characteristics
• Encapsulated in a hermetically sealed glass DO-35 axial package
• Capable of operation across an extended junction temperature range up to 200°C

Single Zener Diodes Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation as onsemi may not be the primary producer of this legacy part number; confirm the actual manufacturer listed on the datasheet or ordering guide. Ensure the T50R suffix corresponds to the correct reel quantity and packaging format required for assembly. Cross-reference the electrical parameters against the official specification sheet to ensure compatibility with the target design requirements.

Single Zener Diodes Selection Notes

Select this component when a standard 27 V Zener voltage is required with moderate precision. The DO-35 package is suitable for through-hole mounting processes. Consider the thermal resistance and power derating curves if the operating environment exceeds standard ambient conditions. Verify that the ±5% tolerance meets the circuit's accuracy specifications.

Single Zener Diodes Part Context

This component belongs to the 1N52xx series of Zener diodes, a widely recognized family of voltage regulator devices. These parts are commonly used in general-purpose electronics for establishing stable reference voltages. The 1N5254B variant specifically targets the 27 V segment of this series, offering a balance between voltage stability and power handling capabilities within a compact axial package.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5254B from Central Semiconductor Corp and Vishay General Semiconductor. Other manufacturers such as Micro Commercial Components (MCC) and Diodes Inc. also produce equivalents under the same base part number. Ensure the replacement maintains the DO-35 package and 500 mW power rating.
