Overview
The Microchip Technology 1N5524UR-1/TR is a low voltage avalanche Zener diode with a nominal breakdown voltage of 5.6 V and a maximum power dissipation of 0.5 W. It features a ±5% voltage tolerance, a test current of 30 mA, and a maximum dynamic impedance of 2.0 Ohms at the test point. The device operates within a junction temperature range of -65°C to +175°C and utilizes a hermetically sealed DO-213AA (MELF) surface mount package.
Feature Summary
- Hermetically sealed glass MELF package construction
- Internal metallurgical bond for enhanced reliability
- Qualified per MIL-PRF-19500/437 standards
- Minimal capacitance characteristics
Applications
- Voltage regulation over broad operating currents
- Circuit protection in harsh environments
- Radiation-hardened electronic systems
Procurement Notes
Verify that the specific part number includes the UR-1 suffix to confirm the surface mount MELF package and internal metallurgical bond configuration. Ensure the B suffix is present if a strict ±5% voltage tolerance is required for the design. Confirm RoHS compliance status based on the commercial grade availability versus military qualification levels.
Selection Notes
Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The 5.6 V nominal voltage and 0.5 W power rating suit compact designs needing stable reference voltages. Consider the wide operating temperature range and radiation hardness for aerospace or industrial deployments.
Part Context
This device belongs to the 1N5518BUR-1 through 1N5546BUR-1 series of low voltage avalanche Zener diodes manufactured by Microchip Technology. The series provides a selection of voltages from 3.3 to 33 volts with various tolerance options. These components are designed for robust performance in demanding electrical environments.
Replacement Considerations
Equivalent parts include other 1N5524 variants such as 1N5524B-1 or 1N5524D-1, provided they match the DO-213AA package and metallurgical bond requirements. Verify that any substitute maintains the same MIL-PRF-19500/437 qualification level if environmental ruggedness is critical.
