1N5228C-TAP

Single Zener Diodes Overview

The Vishay 1N5228C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 3.9 V with a tight ±2 % tolerance, indicated by the 'C' suffix. The device dissipates up to 500 mW at thermal equilibrium and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 10 µA at 1 V and a typical dynamic resistance of 23 Ω at a test current of 20 mA.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2 % Zener voltage tolerance
• Robust thermal performance supporting operation up to a 175 °C junction temperature
• Standardized DO-35 axial leaded package for reliable through-hole mounting

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Overvoltage protection networks

Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly includes the 'C' suffix to ensure the component meets the required ±2 % tolerance specification. Confirm the '-TAP' suffix matches the specific ammopack tape configuration needed for your assembly line equipment. Cross-reference the document revision date against your quality management system requirements to ensure compliance with current manufacturing standards.

Single Zener Diodes Selection Notes

Select this part when circuit design requires tighter voltage accuracy than standard ±5 % devices provide. Ensure the operating current remains near the specified 20 mA test point to maintain optimal regulation stability. Verify that the 500 mW power dissipation rating aligns with the ambient thermal conditions of the final enclosure design.

Single Zener Diodes Part Context

This component 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 using a consistent silicon planar technology. The 1N5228 variant specifically targets applications requiring a stable 3.9 V reference level.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5228B-TAP for standard tolerance or the MMSZ5228-E3-18 for surface mount integration. Ensure any replacement maintains the same DO-35 footprint or utilizes an equivalent SOD-123 package if board space allows.
