1N3044B-1

Single Zener Diodes Overview

The 1N3044B-1 is a 1-watt Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 150 V with a tolerance of ±5%. The device utilizes a DO-204AL (DO-41) axial through-hole package and supports an operating temperature range from -55°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 29.7 V and a maximum forward voltage of 1.2 V at 200 mA. The component employs metallurgical bonding for enhanced reliability under extreme thermal conditions.

Single Zener Diodes Feature Summary

• Metallurgically bonded construction ensures structural integrity and long-term reliability in demanding environments.
• Extended high-temperature operation capability up to +175°C suitable for harsh industrial conditions.
• Low reverse leakage current specification maintains stability during voltage regulation tasks.

Single Zener Diodes Applications

• High-voltage power supply regulation circuits
• Industrial control systems requiring robust voltage references
• Automotive electronics exposed to extreme thermal variations

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against your design specifications before ordering. Confirm that the DO-204AL package dimensions align with your PCB layout constraints. Ensure that the thermal management strategy accounts for the 1-watt power dissipation rating at elevated ambient temperatures. Cross-reference the manufacturing date codes to meet any project-specific traceability or lifecycle requirements.

Single Zener Diodes Selection Notes

Select this component when a stable 150 V reference is required in a through-hole configuration. Consider the ±5% tolerance for precision applications. Evaluate the thermal derating curve if operating near the maximum temperature limit. Compare the reverse leakage specifications against alternative devices to ensure compatibility with low-current circuit designs.

Single Zener Diodes Part Context

This part belongs to the 1N30xxB series of 1-watt Zener diodes produced by Microchip Technology. The series is characterized by its rugged construction and wide operating temperature range. These diodes are commonly used in general-purpose voltage regulation where reliability is critical. The 1N3044B-1 specifically addresses the need for higher voltage regulation in standard axial packages.

Single Zener Diodes Replacement Considerations

Check for direct equivalents within the 1N30xxB family that match the 150 V Zener voltage and 1 W power rating. Verify pinout compatibility for DO-204AL packages. Ensure that replacement parts maintain the same ±5% tolerance and thermal performance characteristics.
