1N5226B-G

Single Zener Diodes Overview

The Comchip Technology 1N5226B-G is a silicon unidirectional voltage regulator diode designed for through-hole mounting in the DO-35 glass axial package. It provides a nominal Zener voltage of 3.3 V with a maximum power dissipation of 0.5 W at 25°C. The device features a tight voltage tolerance of 5% and operates within an extended temperature range from -65°C to +175°C. Key electrical characteristics include a maximum reverse leakage current of 25 µA, a Zener impedance of 28 Ohms, and a forward voltage of 1.1 V. The component is RoHS compliant and halogen-free.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using planar die construction technology
• Encapsulated in hermetically sealed glass DO-35 package for environmental protection
• Compliant with RoHS directives and halogen-free manufacturing standards

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required tolerance grade, as standard variants may differ. Confirm compliance with specific environmental regulations such as RoHS if mandated by the end application. Ensure the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability of the silicon material and packaging integrity.

Single Zener Diodes Selection Notes

Select this component when a low-power, high-reliability voltage reference is needed in an axial leaded form factor. The 5% tolerance offers better precision than standard 10% variants. Consider the thermal derating requirements for operation above 25°C. The glass package provides superior stability compared to plastic alternatives in harsh environments.

Single Zener Diodes Part Context

This component belongs to the 1N522x series of Zener diodes, which are widely recognized industry-standard parts for general-purpose voltage regulation. The 'G' suffix typically denotes RoHS compliance and halogen-free status. It serves as a direct replacement for older commercial-grade versions while maintaining identical electrical pinouts and mechanical dimensions for legacy board designs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N5226B parts with matching 3.3V Zener voltage and 5% tolerance. Verify that alternative sources offer the same DO-35 package and 0.5W power rating. Ensure equivalent thermal performance and leakage current specifications for critical circuit applications.
