1N5250B-T

Single Zener Diodes Overview

The Vishay 1N5250B-T is a silicon planar power Zener diode in the DO-35 (DO-204AH) axial leaded package. It provides a nominal Zener voltage of 20 V with a standard tolerance of ±5%. 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 0.1 µA at 15 V, a dynamic resistance of 25 Ω at a test current of 6.2 mA, and a typical voltage temperature coefficient of 0.086 %/K.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Features a standard ±5% Zener voltage tolerance designation
• Designed for through-hole mounting in an axial leaded package

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the ordering code includes the suffix indicating taped reel packaging. Confirm the specific tolerance class matches the required application specifications. Ensure the component meets the necessary environmental compliance standards for the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a 20 V reference point is required in a through-hole design. Consider the 500 mW power dissipation limit relative to ambient operating temperatures. Evaluate the dynamic impedance and leakage current requirements against circuit sensitivity thresholds.

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 voltage range from 2.4 V to 75 V. Variants are available in MiniMELF, SOT-23, and SOD-123 surface mount packages alongside the traditional DO-35 axial configuration.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' 1N5250B equivalents. Verify that substitute parts match the 20 V nominal voltage, ±5% tolerance, and 500 mW power rating. Confirm physical package compatibility for existing PCB layouts.
