1N3034B-1/TR

Overview

The Microchip Technology 1N3034B-1/TR is a 1-watt glass case Zener diode with a nominal voltage of 39 V and a 5% tolerance. It operates within a temperature range of -55°C to +175°C and features a maximum reverse leakage current of 10 µA at 29.7 V. The device exhibits a dynamic impedance of 60 Ohms at a test current of 6.5 mA, with a forward voltage of 1.2 V at 200 mA. Packaged in a hermetically sealed DO-41 axial leaded format, it is supplied on tape and reel.

Feature Summary

• Hermetically sealed glass package for high-reliability applications
• Metallurgically bonded construction with double plug design
• Qualified per MIL-PRF-19500/115 standards
• Inherently radiation hard

Applications

• Voltage regulation over broad operating currents
• High-reliability military and aerospace circuits
• Radiation-hardened electronic systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration and compliance status. Confirm that the 'TR' designation aligns with the required tape and reel specifications for automated assembly processes. Ensure the component meets all necessary environmental and qualification requirements for the intended deployment environment.

Selection Notes

Select this component when a 39 V reference with tight 5% tolerance is required in a through-hole glass package. Consider its wide operating temperature range and radiation hardness for demanding environments. Verify power dissipation limits and thermal derating curves to ensure safe operation under expected load conditions.

Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. These devices are JEDEC registered and available in commercial, JAN, JANTX, and JANTXV reliability levels. They utilize a standard DO-41 glass axial package suitable for robust mounting and high-voltage regulation tasks.

Replacement Considerations

Consult official substitution lists for equivalent parts from the same manufacturer family or cross-reference compatible components meeting identical electrical and mechanical specifications.
