1N5224C-TAP

Single Zener Diodes Overview

The Vishay 1N5224C-TAP is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial package. It provides a nominal Zener voltage of 2.8 V with a tight ±2% tolerance, indicated by the 'C' suffix. The device operates at a test current of 20 mA and dissipates up to 500 mW. Key electrical characteristics include a maximum reverse leakage current of 75 µA at 1 V and a typical dynamic resistance of 30 Ω at 1 kHz.

Single Zener Diodes Feature Summary

• Tight voltage tolerance of ±2% for precision regulation
• Silicon planar construction for reliability
• High thermal stability across operating temperatures

Single Zener Diodes Applications

• Voltage stabilization circuits
• Precision reference voltage generation
• Over-voltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the -TAP suffix to confirm the specific ammopack tape configuration. Ensure the required tolerance matches the 'C' designation for ±2% accuracy rather than the standard 'B' variant. Confirm the DO-35 leaded package meets the mechanical constraints of the target printed circuit board layout.

Single Zener Diodes Selection Notes

Select this component when a precise 2.8 V reference is required with tighter tolerances than standard Zener diodes offer. The DO-35 package supports through-hole mounting, making it suitable for legacy designs or applications requiring robust mechanical anchoring. Evaluate the 500 mW power dissipation limit against the expected thermal environment to ensure safe operation.

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 1N5224C specifically targets low-voltage applications requiring high accuracy within the axial leaded form factor.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N5224 equivalents in the DO-35 package. Verify that substitute parts meet the ±2% tolerance requirement and maintain similar dynamic resistance and leakage specifications for direct replacement.

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.

What is the maximum power dissipation rating?

The maximum power dissipation is 500 mW at an ambient temperature of 25 °C, provided the leads are maintained at a constant temperature.
