BZX84C6V8-E3-18

Single Zener Diodes Overview

The Vishay BZX84C6V8-E3-18 is a silicon planar Zener diode with a nominal voltage of 6.8 V and a ±5 % tolerance, housed in an SOT-23 package. It operates within a temperature range of -55 °C to +150 °C. The device features a maximum reverse leakage current of 2 μA at 5 V and a dynamic impedance of 15 Ω at a test current of 5 mA. Power dissipation reaches 500 mW on FR-4 boards, with a junction-to-lead thermal resistance of 250 K/W.

Single Zener Diodes Feature Summary

• Silicon planar construction for reliable small-signal regulation
• ESD protection exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant commercial grade material categorization

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage biasing
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape-and-reel dimensions and quantity per reel. Ensure that the component meets RoHS compliance requirements for your manufacturing process. Confirm that the ESD ratings align with your assembly handling protocols. Validate all electrical parameters against the latest datasheet revision before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 6.8 V reference is required in a compact surface-mount footprint. The ±5 % tolerance suits general-purpose applications where tighter grading is unnecessary. Consider the low dynamic impedance for improved regulation under varying load conditions. Evaluate the thermal resistance characteristics to ensure adequate heat dissipation in densely packed circuit layouts.

Single Zener Diodes Part Context

This part belongs to the Vishay BZX84 series of small-signal Zener diodes. The series offers a wide range of standardized voltages from 2.2 V to 75 V. The 'C' designation indicates a standard 5 % voltage tolerance. The '-E3-18' suffix specifies a lead-free, RoHS-compliant version supplied in 10,000-unit reels on 13-inch carriers.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOT-23 packaged Zener diodes with identical 6.8 V nominal voltage and ±5 % tolerance. Verify that substitute parts match the 15 Ω dynamic impedance and 2 μA leakage current limits. Ensure physical pinout compatibility and similar thermal resistance values for direct board replacement.
