1N3013A

Overview

The Microchip Technology 1N3013A is a single Zener diode rated for 220 V nominal voltage with ±5% tolerance. It features a maximum power dissipation of 10 W and operates within a temperature range of -65°C to 175°C. The device utilizes a DO-213AA (DO-4) chassis stud mount package, designed for high-power regulation applications requiring robust thermal management and stable voltage control under varying load conditions.

Feature Summary

• Provides precise voltage regulation at 220 V with tight manufacturing tolerance
• Supports high power dissipation up to 10 W for demanding circuit loads
• Engineered for extended operational reliability across extreme temperature environments

Applications

• High-voltage power supply regulation circuits
• Industrial equipment overvoltage protection systems
• Military-grade electronic assembly voltage reference stages

Procurement Notes

Verify the specific manufacturer lot code and qualification level against project requirements. Confirm that the DO-213AA mounting interface matches the heatsink or chassis specifications. Ensure thermal resistance calculations align with the 10 W power rating to prevent junction overheating during continuous operation.

Selection Notes

Select this component when a fixed 220 V reference is required in high-power scenarios. The stud mount design facilitates direct thermal coupling to large heat sinks. Consider the ±5% tolerance for precision applications where tighter voltage stability might necessitate additional regulation stages or alternative series options.

Part Context

This part belongs to the 1N2970B through 1N3015B series of 10 W Zener diodes manufactured by Microchip. These components are JEDEC registered and often available in qualified levels such as JAN, JANTX, and JANTXV for aerospace and defense sectors. The series covers a broad voltage range from 3.9 V to 200 V, with the 1N3013A representing the higher voltage end of standard commercial offerings.

Replacement Considerations

Cross-reference with other manufacturers offering DO-4 packaged 220 V 10 W Zener diodes. Verify pinout compatibility and thermal characteristics before substitution. Note that military-qualified versions may have different testing standards than commercial equivalents.
