1N5263C-TR

Single Zener Diodes Overview

The Vishay 1N5263C-TR is a silicon planar power Zener diode with a nominal voltage of 56 V and ±2% tolerance. It operates in the DO-204AH (DO-35) axial through-hole package, dissipating up to 500 mW at thermal equilibrium. The device features a maximum reverse leakage current of 0.1 µA at 43 V and a typical dynamic resistance of 150 Ω at a test current of 2.2 mA. It supports junction temperatures up to 175 °C and storage ranges from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance for tight circuit requirements
• Robust thermal stability across an extended operating temperature range
• Low forward voltage drop ensuring minimal conduction losses during non-regulation states

Single Zener Diodes Applications

• Voltage stabilization in electronic circuits
• Precision reference voltage generation
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to confirm the ±2% tolerance specification. Ensure the procurement documentation references the correct DO-204AH axial leaded package variant. Confirm compliance with RoHS3 standards and check material categorization details against the manufacturer's official documentation before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required, as the 'C' suffix denotes tighter manufacturing tolerances compared to standard variants. Consider the 500 mW power dissipation limit and the specific 56 V breakdown voltage. Verify that the axial DO-204AH package dimensions fit the target PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V. The 'C' suffix specifically indicates a tightened tolerance band of ±2%, distinguishing it from the standard ±5% 'B' suffix devices within the same product family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 56 V Zener diodes in the DO-35 package. Verify that replacement parts meet the 500 mW power rating and ±2% tolerance requirements. Check if alternative packages like MiniMELF or SOT-23 are viable for space-constrained designs.
