Overview
The Microchip Technology 1N3016B-1/TR is a 1-watt glass case Zener diode qualified per MIL-PRF-19500/115. It features a hermetically sealed DO-41 package with metallurgically bonded construction and double plug design. The nominal Zener voltage is 6.8 volts at a test current of 37 mA, with a maximum dynamic impedance of 3.5 ohms. Operating temperature ranges from -55°C to +175°C, and it exhibits low reverse leakage currents.
Feature Summary
- Hermetically sealed DO-41 glass package with tungsten slugs
- Metallurgically bonded internal construction
- Qualified for JAN, JANTX, and JANTXV military levels
- Inherently radiation hard
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-reliability applications requiring radiation hardness
- Circuits requiring low reverse leakage currents
Procurement Notes
Verify the specific ordering suffix against the manufacturer's part nomenclature to confirm qualification level (JAN, JANTX, or JANTXV) and RoHS compliance status. Ensure the tape and reel packaging configuration matches the required EIA-296 standard quantities before finalizing procurement orders.
Selection Notes
Select this component for designs requiring high-reliability voltage reference in harsh environments. Consider the 6.8V nominal breakdown and 1W power dissipation limits. Verify thermal derating requirements based on ambient temperature and mounting conditions to ensure operation within the specified junction temperature range.
Part Context
This device belongs to the established 1N3016 through 1N3045 JEDEC registered series. It provides a wide selection of Zener voltages ranging from 6.8 to 110 volts in the same glass DO-41 package. Commercial versions are available alongside military qualifications.
Replacement Considerations
Equivalent surface mount options exist in the DO-213AB package, specifically the 1N3016BUR-1 through 1N3045BUR-1 series. These provide similar electrical characteristics but require different PCB footprint considerations.
