1N5230C-TR

Single Zener Diodes Overview

The Vishay 1N5230C-TR is a silicon planar power Zener diode in the 1N5221 to 1N5267 series, housed in a DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 4.7 V with a tight tolerance of ±2%, 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 5 µA at 3.5 V, a typical dynamic resistance of 19 Ω, and a positive temperature coefficient of 0.03 %/K.

Single Zener Diodes Feature Summary

• High precision voltage regulation achieved through a ±2% Zener voltage tolerance
• Positive temperature coefficient ensures stable voltage behavior across operating temperatures
• Low reverse leakage current minimizes power loss in standby conditions
• Robust thermal performance supports operation up to a junction temperature of 175 °C

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the 'C' suffix to confirm the specific ±2% tolerance variant. Confirm the '-TR' suffix indicates reel packaging for automated assembly processes. Ensure the application environment remains within the specified thermal limits to maintain parameter stability.

Single Zener Diodes Selection Notes

Select this component when precise voltage referencing is required, as the tighter tolerance reduces calibration needs compared to standard variants. Consider the positive temperature coefficient for applications where voltage drift must be predictable or compensated. Verify that the 500 mW power dissipation rating aligns with the circuit's thermal design constraints.

Single Zener Diodes Part Context

This part belongs to the Vishay 1N5221 to 1N5267 family of small signal Zener diodes. The series covers a wide range of nominal voltages from 2.4 V to 75 V. The 1N5230 designation specifically identifies the 4.7 V version within this extensive lineup of general-purpose silicon planar devices.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' 1N5230 equivalents to ensure pinout compatibility and matching electrical parameters. Verify that substitute components meet the same ±2% tolerance and thermal requirements for direct replacement.
