Overview
The Microchip Technology 1N3030BUR-1 is a surface mount Zener diode with a nominal voltage of 27 V. It operates within a temperature range of -55 °C to +175 °C and dissipates up to 1 W. The device features a maximum reverse leakage current of 10 µA at the specified voltage. Electrical characteristics include a test current of 9.5 mA, a maximum dynamic impedance of 35 Ohms at the test point, and a maximum temperature coefficient of 0.096 %/°C.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Metallurgically bonded internal design for enhanced contact stability
- Leadless surface mount package suitable for high-density mounting
- Inherently radiation hard
Applications
- Voltage regulation over broad operating current and temperature ranges
- High-reliability applications requiring low parasitic requirements
- High-density circuit board designs
Procurement Notes
Verify the specific military qualification level (JAN, JANTX, or JANTXV) required for the application, as availability varies by grade. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS versions are available on commercial grades only. Ensure the ordering suffix matches the desired tolerance and packaging configuration before finalizing procurement.
Selection Notes
Select this component when a leadless surface mount equivalent to the JEDEC registered 1N3030B series is needed. The DO-213AB outline provides lower thermal resistance compared to traditional packages. Consider the positive temperature coefficient for voltages above approximately 5 V, which aids in thermal stability during operation.
Part Context
This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These devices serve as leadless surface mount equivalents to the JEDEC registered 1N3016 through 1N3045 number series, offering similar electrical performance in a compact DO-213AB package.
Replacement Considerations
Direct replacements include other parts from the 1N3016BUR-1 to 1N3045BUR-1 series with matching voltage ratings. Verify that substitute components meet the same MIL-PRF-19500/115 qualification levels if military-grade reliability is required.
