1N5230BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5230BUR-1 is a surface-mount Zener diode designed for voltage regulation applications. It operates within the 1N5221BUR-1 through 1N5281BUR-1 series, featuring a metallurgically bonded glass construction in a DO-213AA (SMB) package. The device provides a nominal Zener voltage of 2.4 V with a tolerance of ±5%. It supports a maximum power dissipation of 500 mW and maintains an operating junction temperature range from -65°C to +175°C. The component utilizes a single configuration suitable for compact circuit designs requiring precise voltage reference or protection.

Single Zener Diodes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Microchip Technology prior to procurement. Confirm that the DO-213AA package dimensions align with your PCB footprint requirements. Ensure that the thermal management strategy accounts for the 500 mW power dissipation limit under worst-case operating conditions. Cross-reference the part number suffixes to confirm availability of lead-free variants if required by your manufacturing standards.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference near 2.4 V is required in a surface-mount form factor. The DO-213AA package offers a balance between current handling capability and board space efficiency compared to smaller SMD packages. Consider the ±5% tolerance for precision applications; tighter tolerances may require alternative part numbers within the same series. Evaluate the high-temperature rating for use in automotive or industrial environments where standard commercial grade parts may fail.

Single Zener Diodes Part Context

This part belongs to the 1N5221B series family, which serves as the surface-mount equivalent to the traditional axial leaded 1N5221B through 1N5281B diodes. The BUR-1 designation indicates a specific manufacturing lot or variant within Microchip's portfolio of 500 mW Zener regulators. These devices are engineered to replace older through-hole technologies in modern printed circuit board assemblies while maintaining similar electrical characteristics.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include other manufacturers' DO-213AA packaged Zener diodes rated at 2.4 V with 500 mW power dissipation. Verify pinout compatibility and thermal resistance values before substitution. Generic equivalents must match the 5% voltage tolerance and operating temperature range to ensure circuit functionality remains unchanged.
