1N5250B

Single Zener Diodes Overview

The onsemi 1N5250B is a Zener diode with a nominal voltage of 20.0 V, ranging from 19.000 V minimum to 21.000 V maximum at an test current of 6.2 mA. It features a dynamic impedance (ZZ) of 25 ohms and a knee impedance (ZZK) of 600 ohms at 0.1 mA. The device has a power dissipation rating of 500 mW and operates within a junction temperature range of -65°C to +200°C. Reverse leakage current is limited to 0.1 µA at 15.0 V. The temperature coefficient is 0.086 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a tight tolerance band around the nominal 20 V point.
• Capable of handling high operating temperatures up to 200°C for robust performance in demanding environments.
• Features low reverse leakage current for efficient operation in precision circuits.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise 20 V levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., bulk bag vs. tape and reel) matches your assembly requirements. Confirm that the axial lead package (CASE 017AG) fits your board layout constraints. Ensure thermal management strategies account for the 500 mW dissipation limit and derating factors above 50°C during system integration.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener voltage is required with moderate dynamic impedance characteristics. Consider the 500 mW power rating and axial lead form factor for through-hole implementations. Evaluate the temperature coefficient of 0.086 %/°C against circuit stability needs across the specified operating temperature range.

Single Zener Diodes Part Context

This device belongs to the 1N5221B-1N5252B series of Zener diodes manufactured by onsemi. The series offers a wide range of voltage options from 2.4 V to 24 V in a standardized axial lead glass package. These components are designed for general-purpose voltage regulation and protection tasks in industrial and consumer electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5250B equivalents ensuring matching 20 V nominal voltage, 500 mW power rating, and axial lead package compatibility. Verify electrical parameters such as dynamic impedance and leakage current meet or exceed original specifications.
