1N3016B-1E3

Overview

The Microchip Technology 1N3016B-1E3 is a 1-watt glass case Zener diode qualified per MIL-PRF-19500/115. It features a hermetically sealed DO-41 package with tungsten slugs and metallurgically bonded construction. The nominal Zener voltage is 6.8 volts at a test current of 37 mA, with a maximum dynamic impedance of 3.5 ohms at IZT and 700 ohms at IZK. Maximum reverse leakage current is 150 µA at 5.2 volts, and the temperature coefficient is 0.061 %/°C. It operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Hermetically sealed glass DO-41 package with tungsten slugs for high-reliability applications.
• Qualified per MIL-PRF-19500/115 standards including JAN, JANTX, and JANTXV levels.
• Metallurgically bonded double plug construction ensures structural integrity.
• Inherently radiation hard as described in Microsemi MicroNote 050.

Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-reliability electronic circuits requiring military qualification.
• Radiation-hardened environments.

Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, or JANTXV) and RoHS compliance status. The 'e3' suffix indicates RoHS compliance available on commercial grade only; ensure the selected variant aligns with project environmental requirements. Confirm package type availability as surface mount options exist under different part numbers.

Selection Notes

Select this component for designs requiring a 6.8-volt reference with tight tolerance and low leakage. The DO-41 through-hole package suits standard PCB layouts. Consider thermal derating curves when designing for ambient temperatures above 65°C to maintain the 1-watt power dissipation rating safely.

Part Context

This device belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series covers a voltage range from 6.8 to 110 volts in the same glass DO-41 package. Lower voltage variants are available in the 1N3821 through 1N3828 series.

Replacement Considerations

Equivalent parts include the non-RoHS 1N3016B-1. Surface mount equivalents are available in the DO-213AB package under the 1N3016BUR-1 designation.
