Overview
The DZ23C6V8-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 6.8 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 8 Ω at this current level. Reverse leakage current is specified as 2 μA maximum at the rated voltage, increasing to 3 μA maximum at a lower reverse voltage of 0.1 V. The component supports an operating temperature range from -55 °C to +150 °C and offers ESD protection exceeding 8 kV via the human body model.
Feature Summary
- Silicon planar construction for reliable voltage regulation
- High electrostatic discharge robustness per AEC-Q101 standards
- RoHS-compliant commercial grade configuration
Applications
- Voltage reference circuits requiring stable low-voltage rails
- Protection against overvoltage transients in signal lines
- Clamping applications in general-purpose electronic equipment
Procurement Notes
Verify that the ordering suffix matches the required reel size, as the -18 designation indicates a 10,000-unit tape and reel format on a 13-inch reel. Confirm RoHS compliance status and ensure the specific voltage tolerance aligns with circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a 6.8 V Zener voltage is required in a compact SOT-23 footprint. Ensure the application current does not exceed the 5 mA test current significantly to maintain accuracy within the ±5 % tolerance. Consider the thermal resistance characteristics if power dissipation approaches the 300 mW limit on standard FR-4 boards.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, utilizing standardized E24 grading. The DZ23C6V8 variant specifically targets the 6.8 V segment, offering a balance between low leakage and moderate dynamic impedance suitable for precision analog applications.
Replacement Considerations
Direct substitutes within the same series include other DZ23 variants with different voltage ratings but identical packaging and electrical profiles. Cross-referencing with other manufacturers requires verifying pinout compatibility and ensuring equivalent dynamic resistance and leakage specifications are met.
FAQ
What is the dynamic resistance of the DZ23C6V8-E3-18 at the test current?
The maximum dynamic resistance (ZZ) at the test current of 5 mA is 8 Ω.
Does the DZ23C6V8-E3-18 meet automotive reliability standards?
The base part number without the HE3_A suffix is commercial grade. While it has high ESD capability, AEC-Q101 qualification is typically associated with the HE3_A variant unless explicitly stated otherwise for this specific commercial grade.
What is the maximum reverse leakage current at 6.8 V?
The maximum reverse leakage current (IR) at the rated Zener voltage of 6.8 V is 2 μA.
