1N5229B-1E3

Single Zener Diodes Overview

The Microchip Technology 1N5229B-1E3 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device supports a maximum power dissipation of 500 mW and operates within a temperature range of -65°C to +175°C junction temperature. Packaged in the DO-213AA (SMB) surface-mount format, it provides reliable performance for circuit protection and reference voltage generation tasks.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation through controlled Zener breakdown characteristics
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes hermetically sealed glass encapsulation for environmental durability

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify the specific suffix E3 confirms lead-free compliance and RoHS adherence before procurement. Confirm the package designation matches the required PCB footprint. Ensure the manufacturer source is authorized to guarantee component authenticity and traceability. Check current availability status as production cycles may vary.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulation point is required in a surface-mount configuration. Evaluate the 500 mW power rating against expected operating currents to ensure thermal safety. Consider the DO-213AA package dimensions for board space constraints. Verify that the ±5% voltage tolerance meets the circuit design specifications.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family produced by Microchip Technology. It shares functional similarities with other devices in the 1N52xx series but differs in specific voltage ratings and package types. The 1E3 suffix indicates environmental compliance attributes distinct from non-compliant variants.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5229B without the E3 suffix if lead content is acceptable. Other manufacturers offer equivalent 4.7 V Zener diodes in DO-213AA packages, provided electrical parameters match.
