1N5227B-TR

Single Zener Diodes Overview

The Vishay 1N5227B-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 3.6 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum dynamic resistance of 24 Ω, a reverse leakage current of 15 μA at 1 V, and a typical temperature coefficient of -0.065 %/K. It supports junction temperatures up to 175 °C.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features sharp reverse characteristic curves for precise clamping
• Maintains low reverse leakage current levels
• Includes cathode band marking for polarity identification

Single Zener Diodes Applications

• Voltage stabilization circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the "-TR" suffix to confirm taped and reeled packaging. Ensure the "B" suffix is present to match the specified ±5% voltage tolerance. Confirm the component utilizes the DO-35 glass package and matches the Vishay document number 85588 for accurate technical specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference is required in an axial leaded package. The negative temperature coefficient makes it suitable for applications where thermal stability below 5 V is manageable. Verify that the 500 mW power dissipation rating meets the circuit's steady-state requirements.

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 range of voltages from 2.4 V to 75 V. The "B" suffix denotes the standard ±5% tolerance variant, while "C" indicates tighter ±2% tolerance.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5227B equivalents. Verify that substitute parts maintain the same DO-35 package dimensions, 500 mW power rating, and 3.6 V nominal voltage to ensure mechanical and electrical compatibility.
