1N5252B-TR

Single Zener Diodes Overview

The Vishay 1N5252B-TR is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 24 V with a standard tolerance of ±5%. The device operates at a test current of 5.2 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA, a dynamic resistance of 33 Ω, and a temperature coefficient of 0.088 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a standard ±5% Zener voltage tolerance designated by the 'B' suffix
• Designed for high thermal stability with a junction temperature rating up to 175 °C

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the specific ordering code matches the required tolerance level, as the 'B' suffix indicates ±5% while 'C' denotes ±2%. Confirm that the reel quantity aligns with production requirements, noting that standard reels contain 10,000 units. Ensure the component meets RoHS3 compliance standards if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a precise 24 V reference is needed in a through-hole configuration. Consider the 500 mW power dissipation limit relative to ambient temperatures. Evaluate the dynamic resistance and leakage current specifications against circuit sensitivity requirements to ensure adequate performance under varying load conditions.

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 1N5252 variant specifically targets applications requiring a 24 V breakdown voltage within the standard axial leaded form factor.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5252 equivalents or Vishay's MMSZ5252B-E3-18 in an SOD-123 surface mount package. Verify that any replacement maintains the same 24 V nominal voltage, 500 mW power rating, and compatible package dimensions for board compatibility.

Single Zener Diodes FAQ

What is the dynamic resistance of the 1N5252B-TR?

The typical dynamic resistance (ZZ) at the test current of 5.2 mA is 33 Ω.

How does the 'B' suffix affect the component specification?

The 'B' suffix indicates a standard Zener voltage tolerance of ±5%, whereas a 'C' suffix would indicate a tighter ±2% tolerance.
