BZT52C12-7-G

Single Zener Diodes Overview

The BZT52C12-7-G is a single Zener diode manufactured by Diodes Incorporated, designed for surface-mount applications. It features a nominal Zener voltage of 12 V with a tolerance of ±5%. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -65°C to +150°C. Packaged in the compact SOD-523 (SC-79) form factor, it exhibits a maximum Zener impedance of 25 Ohms at a test current of 5 mA. The component is qualified to AEC-Q101 standards for automotive reliability.

Single Zener Diodes Feature Summary

• Planar die construction ensures stable electrical performance and high reliability under varying thermal conditions.
• Totally lead-free and fully RoHS compliant, supporting environmentally conscious manufacturing processes.
• Qualified to AEC-Q101 standards, ensuring suitability for demanding automotive electronic environments.
• Halogen and antimony-free "Green" device construction minimizes environmental impact.

Single Zener Diodes Applications

• Voltage regulation in automotive electronic circuits
• General-purpose voltage reference applications
• Protection against over-voltage transients in surface-mount designs

Single Zener Diodes Procurement Notes

Verify that the ordering suffix "-G" specifically denotes the Green (halogen-free) variant as defined by Diodes Incorporated documentation. Confirm the package designation matches SOD-523/SC-79 and ensure the AEC-Q101 qualification status aligns with project requirements. Cross-reference the manufacturer part number against official datasheets to validate the 300 mW power rating and 12 V nominal voltage specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode with automotive qualification is required. The SOD-523 package offers space efficiency compared to larger packages like SOD-123. Ensure the circuit design accommodates the 300 mW power dissipation limit and the specific 25 Ohm impedance characteristic at the operating current. Verify compatibility with automated assembly processes due to the small outline package geometry.

Single Zener Diodes Part Context

This component belongs to the BZT52C series of surface mount Zener diodes from Diodes Incorporated. The series utilizes planar die construction and is available in various voltage ratings and packages, including SOD-523 and SOD-123. The BZT52C12-7-G represents the 12 V variant within the 300 mW power class, distinguished by its automotive-grade qualification and halogen-free composition.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZT52C12 variants from Diodes Incorporated such as BZT52C12-7 or BZT52C12T-7, provided they match the SOD-523 package and 300 mW rating. Other manufacturers offering equivalent 12 V, 300 mW SOD-523 Zener diodes may be considered if AEC-Q101 qualification is not strictly mandatory.
