1N5930BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5930BUR-1/TR is a surface-mount Zener diode in the DO-213AB MELF package. It provides a nominal Zener voltage of 16 V with a 5% tolerance. The device operates within a junction temperature range of -65°C to +175°C and features a rated average power dissipation of 1.5 W at 25°C ambient temperature, derating to 1.25 W on FR4 PCBs. Key electrical parameters include a test current of 23.4 mA, dynamic impedance of 10 Ohms, and maximum reverse leakage current of 1 µA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package with metallurgically enhanced internal contacts for high reliability.
• Surface mount equivalent to JEDEC registered axial-leaded series, suitable for high-density mounting.
• Inherently radiation hard design suitable for demanding environments.

Single Zener Diodes Applications

• Voltage regulation over broad ranges of operation current and temperature.
• High density surface mounting applications requiring low parasitic characteristics.
• High reliability applications requiring source control drawing screening.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Confirm that the /TR suffix aligns with standard EIA-481-B tape dimensions. Ensure compatibility with MIL-PRF-19500 screening requirements if specified for your application.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface-mount Zener diode is required for high-reliability designs. Consider the 16 V nominal voltage and 5% tolerance for precise regulation needs. Evaluate thermal resistance values for heat dissipation planning in dense layouts.
