Overview
The DZ23C6V8-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G 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 dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 2 μA at 1 V and a dynamic resistance of 8 Ω at the test current. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common cathode configuration within a single ultra-small SOT-23 surface mount package
- Graded Zener voltages according to the international E24 standard with ±5 % tolerance
- ESD capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping applications for transient voltage protection
- Biasing networks in small signal processing stages
Procurement Notes
Verify compliance requirements against project specifications before ordering. Confirm that the specific part number matches the required tape and reel quantity of 10,000 units per 13-inch reel. Ensure design margins account for the specified thermal resistance values under actual PCB mounting conditions.
Selection Notes
Select this component when a dual common cathode arrangement is needed in a minimal footprint. The 6.8 V rating fits within the E24 standard series suitable for general-purpose logic level shifting or reference generation. Evaluate the 300 mW power dissipation limit relative to ambient temperature derating curves for high-temperature environments.
Part Context
This device belongs to the DZ23-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 in the SOT-23 package. The G3 suffix indicates green commercial grade construction compliant with material categorization definitions.
Replacement Considerations
Direct substitutes within the same series include DZ23C6V2-G3-18 (6.2 V) and DZ23C7V5-G3-18 (7.5 V). Cross-manufacturer replacements must match the SOT-23-3 pinout, 6.8 V nominal voltage, and ±5 % tolerance to ensure functional compatibility.
FAQ
What is the marking code for the DZ23C6V8-G3-18?
The marking code for this device is V51.
Does the DZ23C6V8-G3-18 have AEC-Q101 qualification?
