1N5244D

Single Zener Diodes Overview

The Microchip Technology 1N5244D is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 14 V with a tight tolerance of ±1%. The device operates in a DO-35 axial leaded package, suitable for through-hole mounting. Key electrical specifications include a maximum power dissipation of 500 mW and a Zener impedance of 15 Ohms at a test current of 9 mA. The component supports an operating temperature range from -65 °C to +200 °C, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±1% tolerance
• High thermal stability across extended temperature ranges
• Compact axial leaded package for standard PCB integration

Single Zener Diodes Applications

• Voltage reference circuits requiring high precision
• Overvoltage protection in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N5244D designation is utilized by multiple suppliers including Microchip Technology and onsemi. Confirm that the ±1% tolerance variant matches your design requirements, as other variants like the 1N5244B exist with different tolerances. Ensure the DO-35 package footprint aligns with your PCB layout before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 14 V reference with high accuracy is required. The ±1% tolerance distinguishes it from standard 5% or 10% Zener diodes. Consider the 500 mW power rating for thermal management in enclosed spaces. The wide operating temperature range makes it suitable for industrial or automotive environments where standard commercial parts may fail.

Single Zener Diodes Part Context

The 1N5244D belongs to the broader family of 1N52xx series Zener diodes, which are standardized components widely used in electronics. While the '1N' prefix indicates a JEDEC registration, specific manufacturers like Microchip Technology produce these devices with their own quality controls. This part represents a high-precision subset of the general 14 V Zener category.

Single Zener Diodes Replacement Considerations

The 1N5244B is a common alternative but typically offers 5% tolerance rather than the 1N5244D's 1% precision. Verify that any substitute maintains the same DO-35 package and 500 mW power rating to ensure mechanical and thermal compatibility without redesigning the circuit board.
