Overview
The Microchip Technology 1N3027BUR-1/TR is a surface mount Zener diode with a nominal voltage of 20 V and a 5% tolerance. It operates within a temperature range of -55 °C to +175 °C and dissipates up to 1 W. The device features a DO-213AB (MELF) package, a maximum reverse leakage current of 10 µA, and a dynamic impedance of 22 Ohms at the test current of 12.5 mA.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Metallurgically bonded internal contacts
- Qualified per MIL-PRF-19500/115 standards
Applications
- Voltage regulation in high-density circuit designs
- Low parasitic requirement applications
- High-reliability military environments
Procurement Notes
Verify that the specific ordering suffix matches the required qualification level and RoHS compliance status. Confirm the tape and reel packaging specifications align with automated assembly equipment requirements before finalizing procurement orders.
Selection Notes
Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. Ensure the operating environment stays within the specified thermal limits and that the 20 V breakdown voltage meets the circuit design parameters.
Part Context
This part belongs to the 1N3016B through 1N3045B series, offering leadless surface mount equivalents to traditional axial-leaded JEDEC registered diodes. The series provides a wide selection of voltages from 6.8 V to 110 V in a compact DO-213AB outline.
Replacement Considerations
Direct replacements include other JANTXV or JAN qualified parts within the 1N3016B-1 to 1N3045B-1 series. Verify that any substitute maintains the same DO-213AB footprint and hermetic sealing characteristics.
FAQ
What is the maximum forward voltage of the 1N3027BUR-1?
The maximum forward voltage is 1.2 V at a forward current of 200 mA.
Is the 1N3027BUR-1 radiation hard?
Yes, the device is inherently radiation hard as described in Microsemi MicroNote 050.
