1N3530A

Single Zener Diodes Overview

The 1N3530A is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 33 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 500 mW (0.5 W). It utilizes a silicon construction and operates in a unidirectional configuration. The component is housed in a DO-204AH (DO-35) through-hole package, which is a glass-passivated axial leaded case suitable for standard PCB mounting.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a fixed 33 V reference level
• Utilizes a hermetically sealed glass axial package for environmental protection
• Supports through-hole mounting via the DO-35 form factor

Single Zener Diodes Applications

• Voltage reference circuits requiring a 33 V rail
• Overvoltage protection stages in low-power systems
• Clamping applications in analog signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the manufacturer marking against Microchip Technology specifications to ensure authenticity. Confirm the package type matches DO-35 requirements for your assembly process. Check datasheet revisions for any updates to electrical characteristics or handling instructions before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a precise 33 V Zener reference is required in a through-hole design. Ensure the circuit current does not exceed limits that would cause power dissipation above 500 mW. Consider thermal management if ambient temperatures are high or if multiple devices share limited board space.

Single Zener Diodes Part Context

This part belongs to the 1N35 series of Zener diodes produced by Microchip Technology. The series offers various voltage options within the DO-35 package. The 1N3530A specifically addresses the need for a 33 V regulation point in legacy or industrial designs utilizing standard axial components.

Single Zener Diodes Replacement Considerations

The 1N5546B is an electrically equivalent alternative from Microchip Technology offering the same 33 V Zener voltage and 500 mW power rating in the DO-35 package. Verify pinout compatibility and tolerance specifications before substitution.
