1N5244BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5244BUR-1 is a surface mount Zener voltage regulator in a DO-213AA package. It provides a nominal Zener voltage of 14 V at a test current of 9.0 mA. The device features a maximum dynamic impedance of 15 Ohms and a maximum reverse leakage current of 0.1 µA. It operates within a junction temperature range of -65°C to +175°C with a steady-state power dissipation rating of 0.5 W.

Single Zener Diodes Feature Summary

• Hermetically sealed metallurgically bonded glass surface mount package
• Surface mount equivalent of JEDEC registered 1N5221 thru 1N5281 series
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to ESD

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High reliability applications requiring radiation hardness
• ESD non-sensitive circuit protection

Single Zener Diodes Procurement Notes

Verify the specific tolerance suffix (B indicates 5%) against design requirements, as the base part number denotes standard tolerances. Confirm RoHS compliance status if required, noting that commercial versions may differ from military screening options. Ensure the ordering suffix matches the desired packaging configuration, such as tape and reel availability.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 14 V reference in a compact surface mount form factor. Consider the positive temperature coefficient of +0.082 %/°C for thermal stability analysis. Evaluate the low capacitance characteristics for high-speed switching applications where minimal signal distortion is critical.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of 0.5 watt Zener voltage regulators. The series offers a wide selection of voltages from 2.4 to 200 volts in a metallurgically bonded configuration. It serves as a surface mount alternative to traditional axial-leaded JEDEC registered diodes.

Single Zener Diodes Replacement Considerations

Equivalent axial-leaded parts include the 1N5244B-1 series. Commercial grade RoHS compliant versions are available with an e3 suffix.
