1N5922BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5922BUR-1 is a surface-mountable 1.5 W Zener diode housed in the JEDEC DO-213AB (MELF) package. It provides a nominal Zener voltage of 7.5 V with a test current of 50.0 mA and a dynamic impedance of 3.0 Ohms. The device operates within a junction temperature range of -65°C to +175°C, featuring a maximum reverse current of 6.0 µA at 6.5 V reverse voltage and a rated average power dissipation of 1.5 W.

Single Zener Diodes Feature Summary

• Hermetically sealed glass package with metallurgically enhanced internal contacts for high reliability.
• Surface mount equivalent of the JEDEC registered 1N5913B through 1N5956B axial-leaded series.
• 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 screened in accordance with MIL-PRF-19500.

Single Zener Diodes Procurement Notes

Verify the specific tolerance level suffix (e.g., B for 5%) required for the application, as the base part number covers a voltage range. Confirm RoHS compliance status by checking for the e3 suffix if lead-free composition is mandatory. Ensure sourcing aligns with the manufacturer's official distribution channels to guarantee authenticity and access to relevant screening documentation.

Single Zener Diodes Selection Notes

Select this component when a hermetic surface-mount solution is preferred over standard plastic packages. The DO-213AB MELF form factor offers lower thermal resistance compared to some alternatives. Consider the specified capacitance values relative to the operating frequency requirements. Verify that the 1.5 W power rating accommodates the expected steady-state dissipation on the target PCB footprint.

Single Zener Diodes Part Context

This device belongs to the 1N5913BUR-1 through 1N5956BUR-1 series, which are also identified as CDLL5913 through CDLL5956. These parts serve as surface-mount replacements for traditional axial-leaded Zener diodes, maintaining similar electrical features while providing a compact profile suitable for modern PCB layouts.

Single Zener Diodes Replacement Considerations

Direct functional equivalents include the 1N5922B series in DO-41 axial packages or SMBG(J)5922B in tabbed surface mount formats. When substituting, verify that the replacement package maintains compatible thermal resistance and physical dimensions for the existing footprint.
