1N5231D-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5231D-1/TR is a single silicon Zener diode with a nominal voltage of 5.1 V and a tight tolerance of ±1%. It features a maximum power dissipation of 500 mW, a maximum Zener impedance of 17 ohms, and a maximum reverse leakage current of 5 µA. The device operates within a temperature range of -65 °C to +175 °C and utilizes the DO-35 axial leaded package.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±1% tolerance band for sensitive circuit applications.
• Operates reliably across an extended industrial temperature range up to 175 °C.
• Utilizes a hermetically sealed glass axial package for robust environmental protection.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection in sensitive electronics
• Voltage regulator biasing networks

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm tolerance and packaging variations. Ensure the procurement channel provides valid traceability for aerospace or high-reliability requirements. Confirm RoHS compliance status as historical batches may differ from current production runs.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is required compared to standard tolerance variants. The DO-35 package suits through-hole designs requiring axial mounting. Consider the 500 mW rating for thermal management in enclosed spaces.

Single Zener Diodes Part Context
