1N5229B-TP

Single Zener Diodes Overview

The MCC 1N5229B-TP is a through-hole Zener diode housed in a DO-35 glass package. It provides a nominal Zener voltage of 4.3 V with a ±5% tolerance, tested at a current of 20 mA. The device supports a DC power dissipation of 500 mW and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 1.0 V and a Zener impedance of 22 Ohms at the test current.

Single Zener Diodes Feature Summary

• Utilizes a hermetically sealed glass package for environmental stability
• Supports high-temperature soldering up to 260°C for ten seconds
• Provides precise voltage regulation with tight manufacturing tolerances

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage sources
• Overvoltage protection stages in electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts pose significant risks; unauthorized sources do not provide warranty coverage. Confirm that the ordering suffix matches the required packaging format, such as tape-and-reel or bulk, prior to finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 4.3 V breakdown voltage is required in a standard axial leaded package. Ensure the circuit design accommodates the 500 mW power dissipation limit and applies appropriate derating above 50°C. Verify that the operating environment remains within the specified -55°C to +150°C temperature range for reliable performance.

Single Zener Diodes Part Context

This part belongs to the 1N5221B through 1N5267B series of 500 mW Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 75 V. All devices in this family share the same DO-35 glass encapsulation and thermal characteristics, differing primarily in their specific Zener voltage ratings and associated impedance values.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N5229B equivalents. Verify that substitute components match the 4.3 V nominal voltage, 500 mW power rating, and DO-35 package dimensions to ensure mechanical and electrical compatibility.
