DZ23C24-E3-18

Overview

The DZ23C24-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 24 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and provides a maximum reverse leakage current of 0.05 μA at 19 V. Dynamic resistance is specified at a maximum of 70 Ω at the test current. It is rated for a power dissipation of 300 mW on an FR-4 board and supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common cathode configuration within a compact SOT-23 footprint
• Graded Zener voltages aligned with international E24 standards
• ESD protection capability 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 that the ordering suffix matches the required reel size and minimum order quantity. Confirm RoHS compliance status and ensure the specific part number aligns with the intended manufacturing process requirements before finalizing procurement orders.

Selection Notes

Select this component when a dual common cathode arrangement is necessary within a limited board area. Ensure the circuit design accommodates the 300 mW thermal dissipation limit on standard FR-4 substrates and verify that the 24 V breakdown voltage meets the system's regulation needs.

Part Context

This component belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series utilizes silicon planar technology and offers a wide range of standardized voltage options packaged in the space-efficient SOT-23 form factor for modern surface mount assembly.

Replacement Considerations

Direct substitutes include other DZ23 series variants with identical packaging but different voltage ratings, such as DZ23C22-E3-18 or DZ23C27-E3-18. Cross-series replacements require verification of pinout compatibility and electrical parameter alignment.
