DZ23C33-G3-08

Overview

The DZ23C33-G3-08 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 33 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum dynamic resistance of 80 Ω at this current level. Electrical characteristics include a reverse leakage current of 50 μA at a reverse voltage of 25 V and a temperature coefficient ranging from 8 to 10 × 10⁻⁴/°C. The component supports an operating temperature range 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
• Standardized grading according to international E24 voltage tolerance standards

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in signal processing paths
• Clamping applications within low-power electronic systems

Procurement Notes

Verify that the specific ordering code matches the required voltage tolerance and packaging format. Confirm compliance requirements against the manufacturer's material categorization documentation. Ensure the procurement channel sources units directly from authorized distributors to maintain traceability and quality assurance standards.

Selection Notes

Select this component when a 33 V reference point is needed in a compact SOT-23 footprint. Evaluate the thermal resistance parameters against the expected power dissipation in the target circuit layout. Consider the ±5 % tolerance limits to ensure they align with the precision requirements of the application design.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series encompasses a wide range of voltages from 2.2 V to 75 V, all utilizing the same SOT-23 package geometry. The 'G3' suffix indicates compliance with green commercial grade material specifications.

Replacement Considerations

Direct replacements must match the 33 V nominal voltage, SOT-23-3 package, and common cathode configuration. Verify that alternative manufacturers provide equivalent dynamic resistance and leakage current specifications to ensure circuit performance parity.
