Overview
The Microchip Technology 1N3016B-1E3/TR is a 1-watt glass case Zener diode with a nominal voltage of 6.8 volts and a 5% tolerance. It operates within a junction temperature range of -55°C to +175°C and features a hermetically sealed DO-41 package. The device provides low reverse leakage currents and is inherently radiation hard, making it suitable for high-reliability applications.
Feature Summary
- Hermetically sealed glass DO-41 package
- Inherently radiation hard design
- Low reverse leakage currents
- Non-sensitive to electrostatic discharge
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-reliability military and aerospace systems
- Radiation-hardened electronic circuits
Procurement Notes
Verify the specific suffix 'e3' indicates RoHS compliance for commercial grade versions only. Confirm that the 'TR' suffix denotes tape and reel packaging per EIA-296 standards. Ensure the JAN, JANTX, or JANTXV qualification levels match your system requirements, as these are available separately from the standard commercial version.
Selection Notes
Select this component for applications requiring a 6.8-volt reference with strict tolerance limits. Consider the thermal resistance of 80°C/W when designing heat dissipation strategies. Verify that the 1-watt power dissipation rating aligns with your circuit's maximum expected load conditions at elevated temperatures.
Part Context
This part belongs to the established 1N3016B-1 through 1N3045B-1 series registered with JEDEC. It utilizes a metallurgically bonded double plug construction within a voidless hard glass case containing tungsten slugs. The series covers a wide voltage spectrum from 6.8 to 110 volts in the same physical footprint.
Replacement Considerations
Compatible substitutes include other 1N3016B variants from different manufacturers offering identical DO-41 glass hermetic sealing and 6.8V nominal breakdown characteristics. Ensure any replacement matches the 5% voltage tolerance and radiation hardness specifications required by the original design.
FAQ
Is the 1N3016B-1E3/TR qualified for military use?
The base 1N3016B-1 series is qualified per MIL-PRF-19500/115 for JAN, JANTX, and JANTXV levels. However, the 'e3' suffix specifically denotes RoHS compliance, which is available on commercial grade versions only.
What is the maximum forward voltage of this diode?
The maximum forward voltage (VF) is specified as 1.2 V at a forward current of 200 mA.
