1N3041B-1E3/TR

Overview

The Microchip Technology 1N3041B-1E3/TR is a 1-watt glass case Zener diode with a nominal voltage of 82 volts. It features a hermetically sealed DO-41 package and operates within a junction temperature range of -55°C to +175°C. The device provides a maximum reverse leakage current of 10 µA at the specified voltage and exhibits a maximum temperature coefficient of 0.106 %/°C. Qualified per MIL-PRF-19500/115, it supports JAN, JANTX, and JANTXV reliability levels.

Feature Summary

• Hermetically sealed voidless hard glass package with tungsten slugs for high-reliability applications
• Inherently radiation hard design suitable for demanding environments
• Low reverse leakage currents ensuring stable performance in breakdown region
• Non-sensitive to electrostatic discharge (ESD) events

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability military and aerospace electronic circuits
• Radiation-hardened system protection components

Procurement Notes

Verify that the specific ordering suffix matches the required reliability level, as commercial RoHS-compliant versions differ from military qualified units. Confirm tape and reel packaging availability directly with the manufacturer or authorized distributor, as standard quantities may vary. Ensure the component meets the specific JAN, JANTX, or JANTXV qualification requirements necessary for your application's environmental standards.

Selection Notes

Select this component when a robust 82-volt reference is required in a through-hole glass package. Consider the thermal resistance and power derating curves if operating near the maximum dissipation limits. Verify that the 5% voltage tolerance aligns with circuit precision requirements. Evaluate the package dimensions against available board space constraints before finalizing the design.

Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series offers a wide selection of voltages from 6.8 to 110 volts in the same DO-41 package. It is designed for applications requiring a glass hermetic seal and metallurgically bonded construction. The series includes options for various voltage tolerances and military qualifications.

Replacement Considerations

Compatible substitutes include other 1N3041 variants such as 1N3041B or 1N3041BUR-1, provided they match the DO-41 package and electrical specifications. Verify that any replacement maintains the required hermetic seal and radiation hardness characteristics if applicable to the original design intent.
