Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-08' suffix indicates units are supplied on an 8 mm tape wound on a 7-inch reel. Confirm that the commercial grade designation aligns with environmental specifications. Ensure the component meets all applicable RoHS compliance standards before finalizing procurement orders.

Selection Notes

Select this component when a 68 V Zener voltage is required within a compact SOT-23 footprint. Verify that the 2 mA test current matches the biasing conditions of the target circuit design. Evaluate the thermal dissipation limits relative to the expected ambient temperature and power load to ensure safe operation within the junction temperature constraints.

Part Context

This part belongs to the Vishay DZ23-G series of small signal Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V, offering standardized grading across multiple packages. The DZ23C68 variant specifically addresses mid-range voltage stabilization needs using a common cathode configuration suitable for general-purpose discrete semiconductor applications.

Replacement Considerations

Direct replacements must match the 68 V nominal voltage, ±5 % tolerance, and SOT-23-3 package dimensions. Verify equivalent dynamic resistance and leakage current specifications to maintain circuit performance. Cross-reference thermal resistance values to ensure compatibility with existing board layouts and heat dissipation profiles.
