Overview
The Microchip Technology 1N3033BUR-1/TR is a surface mount Zener diode with a nominal voltage of 36 V and a 5% tolerance. It operates within a junction 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 27.4 V, a dynamic impedance of 0.25 Ohms at the test current of 7.0 mA, and a positive temperature coefficient of 0.100 %/°C.
Feature Summary
- Hermetically sealed glass MELF construction for high reliability
- Leadless surface mount design suitable for high-density applications
- Metallurgically bonded internal contacts to reduce thermal resistance
Applications
- Voltage regulation over broad operating currents and temperatures
- High-reliability military and aerospace systems
- Radiation-hardened electronic circuits
Procurement Notes
Verify that the specific ordering suffix matches the required qualification level (JAN, JANTX, or JANTXV) and RoHS compliance status. Confirm the tape and reel packaging specifications align with automated assembly requirements. Ensure the requested quantity meets the manufacturer's standard reel size constraints.
Selection Notes
Select this component when a hermetically sealed surface mount Zener diode is required for harsh environments. The DO-213AB package provides a leadless footprint ideal for space-constrained designs. Verify that the 36 V breakdown voltage and 1 W power dissipation capabilities meet the circuit's thermal and electrical demands.
Part Context
This part belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These devices are qualified per MIL-PRF-19500/115 and serve as surface mount equivalents to the JEDEC registered 1N3016B-1 through 1N3045B-1 number series in the DO-13 package.
Replacement Considerations
Direct replacements include other parts from the 1N3016BUR-1 to 1N3045BUR-1 series. Cross-reference the specific Zener voltage and tolerance requirements to ensure compatibility with the existing circuit design.
FAQ
What is the polarity orientation for the 1N3033BUR-1?
The device must be operated with the banded end positive with respect to the opposite end for Zener regulation.
Is the 1N3033BUR-1 radiation hard?
Yes, the device is inherently radiation hard as described in Microsemi MicroNote 050.
