1N5253C-TAP

Single Zener Diodes Overview

The Vishay 1N5253C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 25 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates at a test current of 5 mA and dissipates up to 500 mW of power. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 19 V, a typical dynamic resistance of 35 Ω at 5 mA, and a temperature coefficient of 0.089 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% Zener voltage tolerance
• Robust thermal stability with a junction temperature rating of 175 °C
• Low forward voltage drop for efficient circuit integration

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to ensure the required ±2% tolerance specification is met. Confirm the 'TAP' suffix corresponds to the specific ammopack tape configuration required for your assembly line equipment. Cross-reference the document revision date against your quality management system requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical, as the standard ±5% tolerance devices lack the necessary accuracy. Ensure the operating current remains near the specified 5 mA test current to maintain optimal performance. Verify that the 500 mW power dissipation capability aligns with the thermal design of the target application environment.

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 range of nominal voltages from 2.4 V to 75 V. The 1N5253 variant specifically targets applications requiring a stable 25 V reference point within the low-to-medium voltage spectrum.

Single Zener Diodes FAQ

What does the 'C' suffix indicate in the part number?

The 'C' suffix specifies a Zener voltage tolerance of ±2%, which is tighter than the standard ±5% tolerance found in the 'B' suffix variants.

How does the temperature coefficient affect performance?

The device has a positive temperature coefficient of 0.089 %/K, meaning the Zener voltage increases slightly as the junction temperature rises above room temperature.
