DZ23C33-G3-18

Overview

The DZ23C33-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 33 V with a ±5 % tolerance and operates at a test current of 2 mA. The device has a maximum dynamic resistance of 80 Ω and a reverse leakage current of 50 μA at 25 V. Rated for power dissipation up to 500 mW on FR-4 boards, it supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction with standard E24 grading
• Dual common cathode configuration within a compact SOT-23 footprint
• ESD protection exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific suffix against official documentation to confirm tape width and reel dimensions. Confirm RoHS compliance status and material categorization details directly from the manufacturer's declaration before finalizing procurement orders.

Selection Notes

Select this component when a dual common cathode arrangement is required in a minimal SOT-23 footprint. Ensure the application circuit accommodates the specified 2 mA test current and verify that the thermal environment remains within the stated junction temperature limits.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of standardized voltages from 2.2 V to 75 V in a consistent plastic SOT-23 package suitable for automated surface mount assembly processes.

Replacement Considerations

Cross-reference with other DZ23-G series variants or equivalent AEC-Q101 qualified parts if automotive reliability is required. Verify pinout compatibility and electrical parameters match the original design specifications.
