DZ23C5V1-G3-08

Overview

The DZ23C5V1-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 package. It provides a nominal Zener voltage of 5.1 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 2 μA at 3.8 V. Dynamic resistance is specified at 60 Ω (max) at IZT1 and 480 Ω (max) at IZT2. Power dissipation reaches 500 mW on lead-mounted conditions 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 exceeding 8 kV via human body model and 800 V via machine model
• Standardized E24 grading with ±5 % voltage tolerance
• Green commercial grade material compliant with RoHS standards

Applications

• Voltage reference circuits requiring stable low-voltage biasing
• Overvoltage protection stages in signal processing paths
• Clamping applications in consumer electronics and industrial control systems

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required reel quantity and tape specifications. Ensure compliance with regional environmental directives before finalizing procurement orders.

Selection Notes

Select this component when a precise 5.1 V reference is needed within a compact surface-mount footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the dynamic impedance characteristics align with the noise and stability requirements of the target circuit design.

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, all utilizing the same SOT-23 package format. The G3 suffix indicates a lead-free, halogen-free green product configuration suitable for general commercial electronics manufacturing.

Replacement Considerations

Direct replacements must match the 5.1 V nominal voltage, ±5 % tolerance, and SOT-23-3 package dimensions. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit performance parity.
