DZ23C2V2-G3-08

Overview

The Vishay DZ23C2V2-G3-08 is a silicon planar Zener diode from the DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 2.2 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 1 μA at 1 V. Dynamic resistance is specified at 120 Ω (max) at IZT1 and 600 Ω (max) at IZT2. Power dissipation reaches 500 mW on lead-mounted configurations and 300 mW on FR-4 boards. Operating temperature ranges from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable small-signal regulation
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• Compliant with RoHS standards and characterized as green commercial grade

Applications

• Voltage reference circuits requiring low-voltage stability
• Clamping applications for signal lines
• General-purpose voltage regulation in compact electronic assemblies

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's datasheet document number 86341 against the physical marking code V77 found on the device. Confirm that the ordering suffix matches the standard commercial grade specifications. Ensure compliance requirements align with project material categorization standards before finalizing acquisition.

Selection Notes

Select this component when a precise 2.2 V reference is required within a highly constrained footprint. The SOT-23 package accommodates automated surface-mount assembly processes. Evaluate thermal management needs carefully, as power dissipation drops significantly above ambient temperatures exceeding 50 °C on standard PCBs.

Part Context

This part 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, utilizing standardized E24 grading. All variants share identical physical dimensions and electrical testing conditions, differing primarily in breakdown voltage thresholds and corresponding dynamic resistance values.

Replacement Considerations

Direct substitutes include other DZ23C2V2 variants from Vishay or equivalent 2.2 V Zener diodes in SOT-23 packages from other manufacturers, provided they meet the same ±5 % tolerance and thermal rating specifications.
