1N5241BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5241BUR-1 is a surface mount Zener voltage regulator featuring a metallurgically bonded glass DO-213AA (SOD80/MLL34) package. It provides a nominal Zener voltage of 11 V with a test current of 20 mA and a maximum dynamic impedance of 9.5 Ohms at IZT. The device supports a steady-state power dissipation of 0.5 W, operates within a junction temperature range of -65 to +175 °C, and offers a reverse leakage current of 2 µA at the specified voltage.

Single Zener Diodes Feature Summary

• Hermetically sealed surface mount construction with internal metallurgical bond for enhanced reliability.
• Inherently radiation hard design suitable for demanding environments.
• Non-sensitive to electrostatic discharge events per MIL-STD-750 method 1020.
• Minimal capacitance characteristics optimized for high-speed signal integrity.

Single Zener Diodes Applications

• Voltage regulation in broad operating current and temperature ranges.
• Protection circuits requiring minimal capacitance and ESD robustness.
• Radiation-hardened electronic systems.

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix required for the application, as the 'B' designation indicates a 5% tolerance. Confirm RoHS compliance status if environmental regulations apply, noting that commercial versions may differ from screened military equivalents. Ensure the ordering suffix matches the desired screening level relative to MIL-PRF-19500 standards.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for space-constrained designs. The 11 V nominal rating fits standard reference applications. Consider the low standby current and radiation hardness for specialized deployments. Evaluate the thermal resistance parameters against the PCB footprint requirements to ensure adequate heat dissipation during operation.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, which serves as the surface mount equivalent to the JEDEC registered axial-leaded 1N5221 to 1N5281 series. Manufactured by Microsemi (now part of Microchip Technology), these devices utilize a consistent metallurgically bonded glass package to maintain performance across various voltage ratings from 2.4 V to 200 V.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N5241 variants with compatible DO-213AA packages. Verify that substitute parts meet the same hermetic sealing and radiation hardness requirements if applicable. Axial-leaded 1N5241 equivalents require mechanical adaptation due to package differences.
