Overview
The Microchip Technology 1N5525BE3 is a silicon Zener diode housed in a hermetically sealed glass DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 6.2V with a tolerance of 20% and a power dissipation rating of 0.5W. The device operates within an extended temperature range from -65°C to +175°C, ensuring reliability in demanding environments.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Extended high-temperature operational capability up to 175°C
- Axial-leaded DO-35 package design for through-hole mounting
Applications
- Military aerospace circuits requiring radiation and vacuum stability
- High-reliability voltage regulation systems
- Harsh environment electronic instrumentation
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance and lead-free termination status as per manufacturer documentation. Confirm that the 20% tolerance variant meets the circuit requirements, as tighter tolerances may require different part numbers within the same series. Ensure the DO-35 package dimensions align with the PCB layout constraints.
Selection Notes
Select this component when a robust, hermetically sealed Zener regulator is required for high-temperature applications. The 0.5W power rating suits low-current regulation tasks. Verify that the 20% voltage tolerance is acceptable for the specific application, as other variants offer tighter precision.
Part Context
This component belongs to the 1N55xx series of low-voltage avalanche Zener diodes manufactured by Microchip Technology. The series offers a wide selection of voltages ranging from 3.3V to 33V. These devices are qualified under MIL-PRF-19500/437 standards, indicating their suitability for military and aerospace-grade applications.
Replacement Considerations
Compatible substitutes include other hermetically sealed Zener diodes from the 1N55xx series with matching voltage and power ratings. Cross-reference with JAN or JANTX qualified parts if military specifications are strictly required.
