1N5072

Single Zener Diodes Overview

The Microchip Technology 1N5072 is a fused-in-glass, metallurgically bonded Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 16 V with a tolerance of ±5%. The device is rated for a power dissipation of 3 W and utilizes an axial through-hole mounting configuration. This component offers a surge rating ten times greater than conventional 1 W types, ensuring robust performance in demanding circuit environments.

Single Zener Diodes Feature Summary

• Metallurgically bonded junction structure
• High surge current capability compared to standard 1W types

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as historical production involved Microsemi and Actel before acquisition by Microchip Technology. Confirm the package type is axial leaded and the voltage rating matches the specific 16 V requirement. Ensure datasheet versions align with current Microchip specifications to avoid discrepancies in electrical characteristics or marking codes.

Single Zener Diodes Selection Notes

Select this component when a stable 16 V reference is required with higher surge tolerance than lower-power alternatives. Consider the 3 W power dissipation limit and thermal management needs for continuous operation. Verify that the axial through-hole form factor fits the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N507x series of 3 W Zener diodes. Originally produced by Microsemi Corporation and later Actel, these components are now under the Microchip Technology portfolio. The series provides various voltage options within the same physical and electrical framework, standardized for industrial and commercial voltage regulation tasks.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 16 V, 3 W axial Zener diodes from manufacturers such as Vishay or ON Semiconductor, provided they meet the ±5% tolerance and surge rating requirements. Cross-reference datasheets for pinout compatibility and thermal resistance values.
