1N3037B-1

Single Zener Diodes Overview

The 1N3037B-1 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 51V and operates at a test current of 5mA. The device exhibits a Zener impedance of 95 Ohms and is housed in an axial DO-41 package suitable for through-hole mounting. This component belongs to the broader family of 10W Zener diodes qualified under MIL-PRF-19500/124 standards, offering reliable performance within its specified electrical parameters.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a nominal breakdown voltage of 51V
• Constructed in a robust axial DO-41 package for through-hole integration
• Qualified per military reliability standards including JAN, JANTX, and JANTXV levels

Single Zener Diodes Applications

• Voltage reference circuits requiring precise regulation
• Overvoltage protection stages in electronic systems
• Power supply output stabilization modules

Single Zener Diodes Procurement Notes

Verify the specific qualification level suffix (e.g., -1) against project requirements, as the base part number covers multiple reliability grades. Confirm RoHS compliance status directly with the manufacturer, as indicated by available documentation. Ensure the axial DO-41 footprint matches the target PCB layout constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 51V regulation point is required in a through-hole configuration. Compare the 95 Ohm impedance against circuit sensitivity requirements. Consider the broader 1N3037 series variants if different tolerance or power dissipation characteristics are needed for the specific application environment.

Single Zener Diodes Part Context

This device is part of the 1N2970B through 1N3015B series of 10W Zener diodes. These components are JEDEC registered and offer voltage regulation values ranging from 3.9V to 200V. The series is widely used in industrial and military applications where high reliability and standardized form factors are critical for system integrity.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 51V Zener diodes in the DO-41 package with comparable impedance and power ratings. Verify that any replacement meets the same MIL-PRF-19500/124 qualification standards if military-grade reliability is mandated for the assembly.
