Overview
The Microchip Technology 1N5521C/TR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.3 V with a tolerance of ±2%. The device operates in the through-hole DO-204AH (DO-35) axial package and dissipates up to 500 mW. Key electrical characteristics include a maximum Zener impedance of 18 Ohms at a test current of 20 mA, a reverse leakage current of 3 µA at 1.5 V, and a forward voltage of 1.1 V at 200 mA. It supports an operating junction temperature range from -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation with tight ±2% tolerance for precision circuits
- Capable of operation across extended industrial and military temperature ranges
- Utilizes glass axial encapsulation for reliable through-hole mounting
Applications
- Precision voltage reference sources
- Overvoltage protection circuits
- Voltage clamping applications
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the specific suffix indicates tape and reel packaging. Ensure compliance with relevant environmental regulations prior to integration into final assemblies.
Selection Notes
Select this component when a low-voltage reference requires high accuracy within a standard axial package. Consider the thermal dissipation limits and impedance characteristics relative to the circuit load requirements. Verify that the through-hole form factor aligns with the target PCB layout constraints.
Part Context
This part belongs to the 1N5521 series of low-power Zener diodes manufactured by Microchip Technology. It serves as a specialized variant offering tighter voltage tolerance compared to standard commercial grades, suitable for demanding electronic environments requiring consistent performance.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include 1N5521C, 1N5521D, and 1N5521D/TR. These alternatives share identical electrical specifications and package dimensions.
