1N5263C-TAP

Single Zener Diodes Overview

The Vishay 1N5263C-TAP is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in an axial DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 56 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates at a test current of 2.2 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 43 V and a typical dynamic resistance of 150 Ω.

Single Zener Diodes Feature Summary

• High precision voltage regulation with ±2% tolerance for stable reference applications
• Robust thermal performance supporting operation up to 175 °C junction temperature
• Standardized axial leaded construction suitable for through-hole mounting

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision voltage references
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the specific 'TAP' suffix to ensure receipt in ammopack tape format rather than standard reel packaging. Confirm the 'C' designation matches the required ±2% tolerance specification for the design. Cross-reference the document revision date against manufacturing records to ensure compliance with current material categorization standards.

Single Zener Diodes Selection Notes

Select this component when a precise 56 V reference is required with tighter tolerances than standard ±5% variants offer. Ensure the circuit design accommodates the 2.2 mA test current for accurate voltage regulation. Verify that the DO-35 package dimensions fit the available board space and that the 500 mW power dissipation rating meets the thermal requirements of the application environment.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 75 V. The 'C' suffix denotes a tighter manufacturing tolerance compared to the standard 'B' suffix, making it suitable for applications requiring higher accuracy in voltage regulation or reference generation.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include the 1N5263B-TAP, which offers the same electrical characteristics but with a wider ±5% tolerance.
