1N5234

Single Zener Diodes Overview

The SMC Diode Solutions 1N5234 is a silicon planar power Zener diode housed in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 6.2 V with a standard tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW at ambient temperatures up to 75°C and supports junction temperatures up to 175°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at the rated voltage and a knee impedance of 1000 Ω. It is designed for unidirectional operation in voltage regulation and reference applications.

Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as the 1N5234 part number is utilized by multiple semiconductor vendors including Microchip Technology, General Semiconductor, and others. Confirm that the supplier is SMC Diode Solutions specifically, as component specifications such as tolerance and packaging may vary between manufacturers despite sharing the same JEDEC-style identifier. Ensure the datasheet matches the required electrical parameters before procurement.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V Zener reference is required in an axial through-hole configuration. The 500 mW power rating suits low-current regulation tasks. Verify that the ±5% tolerance meets circuit precision requirements. Consider the DO-35 package dimensions for PCB layout compatibility. Ensure the operating environment remains within the specified thermal limits to maintain voltage stability.

Single Zener Diodes Part Context

The 1N5234 belongs to the broader family of standard Zener diodes used for basic voltage control. It is commonly found in power supply feedback loops and signal conditioning stages. While many manufacturers produce devices under this identifier, SMC Diode Solutions offers it as a discrete component for general-purpose electronic designs requiring reliable voltage referencing.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5234 variants, such as those from Microchip Technology or General Semiconductor, provided they share the 6.2 V rating, 500 mW power dissipation, and DO-35 package. Cross-referencing specific electrical tolerances and thermal characteristics is essential to ensure functional equivalence.
