1N5223B

Single Zener Diodes Overview

The onsemi 1N5223B is a single silicon Zener diode housed in a DO-35 axial lead glass package. It provides a nominal Zener voltage of 2.7 V with a maximum tolerance of ±5%. The device dissipates up to 500 mW at 25°C and operates within a junction temperature range of -65°C to +200°C. Electrical characteristics include a maximum dynamic impedance of 30 Ohms, a reverse leakage current of 75 µA at 1.0 V, and a temperature coefficient of -0.080 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using a single unidirectional Zener junction
• Constructed with hermetically sealed glass encapsulation for environmental protection
• Designed for through-hole mounting via an axial lead configuration

Single Zener Diodes Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Overvoltage protection stages in electronic power supplies
• Clamping applications in signal processing pathways

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm shipping format, as bulk bags and tape-and-reel options exist within this series. Confirm RoHS compliance status and ensure the selected variant matches the required packaging specifications for automated assembly or manual insertion processes.

Single Zener Diodes Selection Notes

Select this component when a 2.7 V regulation point is required with a standard 5% tolerance. Evaluate the thermal management requirements to ensure the 500 mW dissipation limit is not exceeded during continuous operation. Consider the negative temperature coefficient when designing circuits that must maintain stability across wide ambient temperature variations.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5252B series of 0.5 W Zener Voltage Regulators. The series offers a broad selection of voltages from 2.4 V to 24.0 V in standard DO-35 packages. These components are widely utilized in general-purpose electronics where reliable, low-power voltage stabilization is necessary.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5223B equivalents to verify pinout compatibility and electrical parameter alignment. Ensure any substitute maintains the same DO-35 package dimensions and thermal dissipation capabilities.
