1N3020B-1/TR

Overview

The Microchip Technology 1N3020B-1/TR is a 1-watt Zener diode with a nominal voltage of 10 V and a 5% tolerance. It operates within a temperature range of -55°C to +175°C, featuring a maximum reverse leakage current of 25 µA at 7.6 V and a dynamic impedance of 7 Ohms at a test current of 25 mA. The device utilizes a hermetically sealed DO-41 glass package with metallurgic bonding and is supplied in tape and reel packaging.

Feature Summary

• Hermetically sealed glass DO-41 package with tungsten slugs for high-reliability applications
• Qualified per MIL-PRF-19500/115 standards for JAN, JANTX, and JANTXV levels
• Metallurgically bonded double plug construction
• Inherently radiation hard

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability electronic circuits requiring hermetic sealing
• Radiation-hardened environments

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm qualification level and compliance status. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the ordering part number matches the exact JEDEC registration and tolerance specifications required by the design.

Selection Notes

Select this component when a 10 V reference with 5% tolerance is needed in a through-hole glass package. Consider the wide operating temperature range and radiation hardness for demanding environments. Verify thermal derating curves if operating near the maximum power dissipation limit.

Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series covers a voltage range from 6.8 V to 110 V in the DO-41 package. Commercial versions are available alongside military qualifications.

Replacement Considerations

Equivalent parts include JAN1N3020B-1, JANTX1N3020B-1, and JANTXV1N3020B-1. Surface mount equivalents are available in the 1N3020BUR-1 series using the DO-213AB package.
