1N5250BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5250BUR-1 is a surface mount Zener voltage regulator in a DO-213AA package. It provides a nominal Zener voltage of 20 V with a 5% tolerance at a test current of 6.2 mA. The device dissipates up to 0.5 W and operates between -65°C and +175°C. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a dynamic impedance of 25 Ohms, and a temperature coefficient of +0.086 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

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 suffix requirements for your application. Confirm that the metallurgically bonded construction aligns with your environmental constraints. Ensure the thermal resistance values are considered during PCB layout to maintain safe junction temperatures under steady-state power dissipation conditions.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount equivalent to the axial 1N5250B is required. Consider the positive temperature coefficient for stability above 5V. Evaluate the low capacitance characteristics if high-speed switching or minimal signal distortion is necessary within the circuit design.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount counterpart to the JEDEC registered 1N5221 through 1N5281 axial series. The series covers Zener voltages from 2.4 V to 200 V in a compact MELF-style configuration suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

The 1N5250B is the direct axial leaded equivalent. Verify pinout compatibility and physical footprint differences when transitioning between the DO-213AA surface mount package and the DO-35 axial package.
