1N5244

Single Zener Diodes Overview

The 1N5244 is a silicon planar power Zener diode manufactured by SMC Diode Solutions. It is designed for voltage regulation and reference applications with a nominal Zener voltage of 14 V at a test current of 9 mA. The device features a standard tolerance of ±5% and a maximum power dissipation of 500 mW. It operates within a temperature range of -65°C to +200°C and utilizes a DO-35 axial through-hole package.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust performance
• Provides stable voltage regulation with ±5% tolerance
• Supports high operating temperatures up to 200°C

Single Zener Diodes Applications

• Voltage regulation circuits
• Voltage reference sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as SMC Diode Solutions lists this part as obsolete. Confirm availability of parametric equivalents or direct substitutes from other vendors such as Central Semiconductor or onsemi if new production units are required. Ensure the replacement matches the 14V Zener voltage, 500mW power rating, and DO-35 package dimensions.

Single Zener Diodes Selection Notes

Select this component for general-purpose low-power Zener applications requiring a 14V reference. Consider the DO-35 package constraints for board space. Verify that the 500mW power dissipation is sufficient for the expected thermal environment. Check for alternative manufacturers if the original source is discontinued.

Single Zener Diodes Part Context

The 1N5244 belongs to the standard 1N52xx series of Zener diodes, widely used in electronic circuits for voltage clamping and regulation. While originally produced by General Semiconductor and later acquired, SMC Diode Solutions has listed this part number in their portfolio. The 'B' suffix typically denotes the ±5% tolerance variant.

Single Zener Diodes Replacement Considerations

SMC Diode Solutions indicates the 1N5244 is obsolete. Direct substitutes include parts from Central Semiconductor Corp (e.g., 1N5244B TR PBFREE) and onsemi (1N5244B). These alternatives offer identical electrical specifications and mechanical footprint.
