Overview
The 1N5523BE3 is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a standard tolerance of ±5%. The device operates within a power dissipation rating of 500 mW and is tested at a current of 5 mA. Key electrical parameters include a maximum reverse leakage current of 2 µA and a Zener impedance of 26 Ohms. It supports a wide operating temperature range from -65 °C to +175 °C junction temperature. The component is available in the DO-213AA (MELF) surface-mount package.
Feature Summary
- Provides stable voltage regulation with low noise characteristics suitable for sensitive circuits.
- Features internal metallurgical bond construction for enhanced reliability.
- Available in RoHS-compliant versions for commercial grade applications.
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix 'E3' confirms RoHS compliance status as per manufacturer documentation. Confirm the package type matches the required DO-213AA footprint during integration. Ensure the ±5% voltage tolerance aligns with circuit design requirements. Check for any recent Product Change Notifications regarding assembly sites or labeling updates.
Selection Notes
Select this component when a 5.1 V regulation point is required in a compact surface-mount form factor. The 500 mW power rating dictates thermal management considerations for the application environment. Verify that the 26 Ohm impedance meets the dynamic performance needs of the load. Consider the extended temperature range if operation exceeds standard industrial limits.
Part Context
This part belongs to the 1N5518B through 1N5546B series of low noise Zener diodes. The series offers various voltage options ranging from 3.3 V to 33 V. These devices are qualified under MIL-PRF-19500/437 for military grades, while the E3 suffix denotes commercial RoHS-compliant versions. The series utilizes glass surface mount technology for robust performance.
Replacement Considerations
Consult official substitution lists for equivalent parts such as JAN1N5523BUR-1 for military-grade specifications. Verify compatibility with other manufacturers' DO-213AA MELF packages before implementation.
