Overview
The 1N5523BE3/TR is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device operates in the SMD/SMT package DO-213AA-2 and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 2 uA, a Zener impedance of 26 Ohms at a test current of 5 mA, and a forward voltage of 1.1 V. It supports a wide operating temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation with a 5.1 V nominal output.
- Capable of handling power dissipation up to 500 mW.
- Operates reliably across an extended industrial temperature range.
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance as per RoHS standards. Confirm the 'TR' designation corresponds to the reel packaging format required for automated assembly processes. Ensure the DO-213AA-2 footprint matches the target PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a precise 5.1 V reference is needed in a compact surface-mount form factor. The low leakage current and defined impedance make it suitable for sensitive analog sections. Consider the thermal management requirements given the 500 mW power rating and the specific package thermal characteristics.
Part Context
This part belongs to the standard Zener diode family produced by Microchip Technology. It serves as a discrete semiconductor solution for basic voltage regulation tasks within larger electronic systems. The component is categorized under Diodes & Rectifiers and is distinct from integrated circuit regulators or high-power rectifiers.
Replacement Considerations
Check for direct cross-references from other manufacturers offering identical 5.1 V, 500 mW specifications in the DO-213AA-2 package. Verify pinout compatibility and thermal performance metrics before substituting with generic equivalents.
