1N5244A/TR

Single Zener Diodes Overview

The Microchip Technology 1N5244A/TR is a 500 mW glass axial-lead Zener diode housed in a DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 14 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 10 µA at 9.5 V. Electrical characteristics include a test current of 20 mA, a maximum Zener impedance of 0.1 Ohms at 0.25 mA, and a positive voltage temperature coefficient of +0.082 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance suitable for high-frequency applications
• Inherently radiation hard per MicroNote 050

Single Zener Diodes Applications

• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'TR' suffix indicates tape and reel packaging compliant with EIA-296 standards. Confirm the 'A' suffix corresponds to the necessary ±10% voltage tolerance. Ensure the component meets RoHS compliance requirements if applicable to the assembly process.

Single Zener Diodes Selection Notes

Select this component when a 14 V Zener voltage with 500 mW power dissipation is required. The DO-35 through-hole package is suitable for standard PCB mounting. Consider the positive temperature coefficient for thermal stability analysis. Verify that the low leakage current and impedance meet circuit precision requirements.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 V to 200 V. These devices are JEDEC registered and utilize hermetically sealed glass axial-lead construction. The series supports various screening levels and tolerance options via specific suffixes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5244A in the DO-213AA MELF style package. Other manufacturers may offer compatible parts within the same voltage and power class.
