1N5244BTR

Single Zener Diodes Overview

The 1N5244BTR is a single Zener diode manufactured by Fairchild Semiconductor, designed for voltage regulation in through-hole applications. It features a nominal Zener voltage of 14 V with a tolerance of ±5%. The device has a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to 200°C. Key electrical characteristics include a maximum dynamic impedance of 15 Ohms and a reverse leakage current of 100 nA at 10 V. The forward voltage is specified as 1.2 V at 200 mA. It is housed in the DO-204AH (DO-35) axial leaded package.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single Zener diode configuration
• Capable of operating across an extended temperature range from -65°C to 200°C
• Utilizes a glass-passivated junction for reliable performance in through-hole mounting

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection in electronic systems
• Clamping applications for signal lines

Single Zener Diodes Procurement Notes

Verify the manufacturer part number 1N5244BTR against official Fairchild Semiconductor documentation to confirm specifications. Ensure the component matches the DO-204AH package style and 14 V Zener voltage rating required for the design. Cross-reference datasheets for impedance and leakage parameters to validate suitability for specific circuit conditions before procurement.

Single Zener Diodes Selection Notes

Select this component when a 14 V Zener voltage with ±5% tolerance is required for through-hole assembly. Consider the 500 mW power dissipation limit and the 15 Ohm dynamic impedance for regulation accuracy. The wide operating temperature range supports use in harsh environments where standard commercial grade parts may fail.

Single Zener Diodes Part Context

This component belongs to the 1N52xx series of Zener diodes produced by Fairchild Semiconductor. These devices are silicon planar passivated junction diodes intended for general-purpose voltage regulation. The 'B' suffix typically denotes a ±5% tolerance band, distinguishing it from other precision or loose tolerance variants within the same family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include 1N5244B from other manufacturers such as EIC, provided they meet the same 14 V, 500 mW, and DO-204AH package specifications. Verify pinout compatibility and thermal characteristics when replacing.
