BZX84B68-G3-08

Single Zener Diodes Overview

The BZX84B68-G3-08 is a silicon planar Zener diode from the Vishay BZX84-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 68 V with a tight tolerance of ±2%. The device operates at a test current of 2 mA and dissipates up to 500 mW on lead or 300 mW on an FR-4 board. Key electrical characteristics include a maximum reverse leakage current of 50 µA at 47.6 V and a dynamic resistance of 240 Ω.

Single Zener Diodes Feature Summary

• Utilizes silicon planar technology for robust performance
• Offers high precision with ±2% Zener voltage tolerance
• Complies with RoHS standards using green molding compound

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix G3-08 against the official datasheet to confirm commercial grade status and reel specifications. Ensure that the required ±2% tolerance aligns with the 'B' designation in the ordering code rather than the standard 'C' variant. Confirm AEC-Q101 qualification requirements separately if automotive compliance is necessary.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical due to its narrow ±2% tolerance band. The SOT-23 package facilitates automated surface-mount assembly. Consider the thermal resistance values when designing for high ambient temperatures to ensure power dissipation limits are not exceeded.

Single Zener Diodes Part Context

This part belongs to the BZX84-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V. The 'G3' suffix indicates compliance with environmental directives, while '08' specifies the 8 mm tape packaging format.

Single Zener Diodes Replacement Considerations

Substitutes must match the 68 V nominal voltage, ±2% tolerance, and SOT-23 footprint. Verify equivalent dynamic resistance and leakage current specifications to maintain circuit performance.
