1N5247BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5247BUR-1 is a surface mount Zener voltage regulator in a DO-213AA package. It provides a nominal Zener voltage of 17 V with a test current of 7.4 mA and a maximum dynamic impedance of 600 Ohms at this current. The device features a steady-state power dissipation of 0.5 W, a reverse leakage current of 0.1 µA at the specified voltage, and a positive temperature coefficient of +0.084 %/°C. It operates within a junction and storage temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to electrostatic discharge
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Reference voltage generation in electronic circuits
• Protection against voltage transients

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (B for 5%) matches design requirements. Confirm RoHS compliance status if environmental regulations apply, as commercial versions may differ from military screening options. Ensure the DO-213AA footprint aligns with PCB layout guidelines provided in the datasheet.

Single Zener Diodes Selection Notes

Select based on required Zener voltage stability and thermal management needs. Consider the positive temperature coefficient for high-voltage applications above 6.8 V. Evaluate the low leakage current and minimal capacitance for precision or high-frequency signal integrity requirements.

Single Zener Diodes Part Context

This component belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, offering surface mount equivalents to JEDEC registered axial-leaded diodes. The series covers voltages from 2.4 V to 200 V in a compact MELF-style package suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct surface mount equivalents include the 1N5247B-1 in DO-35 axial packaging. Other series members like 1N5246BUR-1 or 1N5248BUR-1 offer adjacent voltage ratings but require circuit adjustment.
