1N3039B-1

Single Zener Diodes Overview

The 1N3039B-1 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 62 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and operates in a through-hole DO-204AL (DO-41) package. Electrical characteristics include a test current of 4 mA and an impedance of 125 Ohms. The component supports an operating temperature range from -55 °C to 175 °C, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 62 V with high precision tolerance
• Capable of handling 1 W power dissipation in a robust glass case
• Engineered for extended thermal operation up to 175 °C

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 62 V levels
• Overvoltage protection in industrial electronic systems
• Power supply regulation modules

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as JANTX or JANTXV may indicate different quality grades or testing standards despite sharing the base model number. Confirm package type compatibility with existing PCB footprints. Ensure that the authorized distributor provides traceability documentation required for critical applications. Cross-reference datasheet revisions to confirm electrical parameter consistency before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a fixed 62 V regulation point is required within a 1 W power budget. The DO-204AL package suits through-hole assembly processes. Consider the ±5% tolerance if tighter voltage accuracy is needed, in which case alternative series should be evaluated. The wide temperature range makes it suitable for harsh environment deployments where standard commercial grade parts would fail.

Single Zener Diodes Part Context

This part belongs to the 1N3039 series of silicon Zener diodes originally developed by Microsemi Corporation and now produced under Microchip Technology. The series utilizes a glass passivated junction for stability. The -1 suffix typically denotes a specific manufacturing lot or regional origin variant, often associated with Philippines production as indicated in product metadata.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3039B equivalents meeting identical 62 V/1 W specifications. Verify pinout compatibility and thermal resistance values. Note that military-grade variants like JANTX1N3039B-1 offer enhanced screening but must be validated for functional interchangeability.
