• Inherently radiation hard per Microsemi specifications
• Non-sensitive to ESD

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• Spacecraft avionics data acquisition and control systems
• Radiation-hardened electronic circuits

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the part number suffix matches the required tolerance level and RoHS compliance status. Ensure the package type corresponds to the intended PCB footprint. Review the datasheet for specific screening options if MIL-PRF-19500 standards are required for the application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The 1N5262BUR-1 provides a direct surface mount alternative to axial-leaded equivalents. Consider the 5% voltage tolerance and radiation hardness for aerospace or industrial environments where standard commercial packages may be insufficient.

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 covers a voltage range from 2.4 V to 200 V in a metallurgically bonded configuration. It serves as a surface mount equivalent to the popular JEDEC registered 1N5221 to 1N5281 series, maintaining similar electrical performance in a compact form factor.

Single Zener Diodes Replacement Considerations

The 1N5262B/TR is a parameter-equivalent through-hole replacement option.
