BZT52B12 RHG

Single Zener Diodes Overview

The BZT52B12 RHG is a small signal Zener diode manufactured by Taiwan Semiconductor. It operates with a nominal Zener voltage of 12 V and features a power dissipation rating of 410 mW. The component provides a tight voltage tolerance of ±2% at the test current of 5 mA. It utilizes an SOD-123F surface mount package, ensuring compatibility with automated assembly processes while maintaining high reliability in compact electronic designs.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±2% tolerance band for stable reference applications
• Utilizes a compact SOD-123F surface mount package designed for efficient PCB space utilization
• Constructed with matte tin lead finish to ensure compliance with RoHS directives and environmental standards

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in sensitive signal paths
• Clamping applications in general-purpose electronic equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix 'RHG' against the manufacturer's official datasheet to confirm packaging configuration and date code alignment. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Cross-reference the part number with the latest product change notifications to verify material composition and manufacturing origin consistency.

Single Zener Diodes Selection Notes

Select this component when a 12 V regulation point is required with strict tolerance limits. The 410 mW power rating suits low-power signal conditioning tasks rather than high-current power regulation. Confirm that the SOD-123F footprint matches the design layout constraints and that the operating temperature range aligns with the system environment requirements.

Single Zener Diodes Part Context

This device belongs to the BZT52B series of small signal Zener diodes from Taiwan Semiconductor. The series offers a wide selection of voltage values within the SOD-123F package format. It is engineered for general-purpose applications where size constraints and regulatory compliance are primary design drivers.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' SOD-123 packaged Zener diodes with 12 V nominal voltage, 410 mW power rating, and ±2% tolerance. Verify electrical characteristics and thermal resistance match before implementation.
