1N5229B TR TIN/LEAD

Single Zener Diodes Overview

The 1N5229B TR TIN/LEAD is a single Zener diode manufactured by Central Semiconductor Corp. It features a nominal Zener voltage of 4.3 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +200°C. Packaged in the DO-35 axial leaded format, it exhibits a maximum reverse leakage current of 5 µA and a Zener impedance of 22 Ohms at a test current of 20 mA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance band around the nominal 4.3 V setpoint.
• Engineered for high-temperature reliability with an operational limit extending up to +200°C junction temperature.
• Utilizes a standard DO-35 through-hole package suitable for automated insertion and manual assembly processes.

Single Zener Diodes Applications

• Precision voltage reference circuits requiring low drift characteristics
• Over-voltage protection stages in sensitive analog signal paths
• Clamping applications in high-temperature industrial control environments

Single Zener Diodes Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm material composition and packaging configuration. Ensure that the tin/lead termination type aligns with applicable environmental compliance standards for the intended deployment region. Cross-reference the exact part number with authorized distributor catalogs to validate current availability status and manufacturing origin before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when circuit design demands superior voltage accuracy compared to standard five-percent tolerance devices. The extended thermal rating makes it appropriate for enclosed or high-ambient-temperature installations where standard silicon limits might be exceeded. Confirm that the 500 mW power rating adequately supports the expected operating current without requiring additional thermal management structures.

Single Zener Diodes Part Context

This component belongs to the 1N5229 series of axial glass-passivated Zener diodes produced by Central Semiconductor. The series offers various voltage options within the DO-35 package form factor. The specific 1N5229B variant distinguishes itself through tighter manufacturing tolerances, catering to applications where standard commercial-grade precision is insufficient for maintaining stable reference potentials under varying load conditions.

Single Zener Diodes Replacement Considerations

Direct substitutes include Vishay Semiconductors 1N5229B and Winnerjoin 1N5229B. Verify pinout compatibility and ensure that alternative manufacturers meet the same ±2% voltage tolerance and 500 mW power dissipation specifications to maintain circuit integrity.
