DZ23C12-G3-18

Overview

The DZ23C12-G3-18 is a dual common cathode silicon planar Zener diode array from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides two independent Zener elements with a nominal voltage of 12 V and a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.1 μA at 9 V and a dynamic resistance of 20 Ω at a test current of 5 mA.

Feature Summary

• Dual common cathode configuration for space-efficient circuit designs
• Silicon planar construction ensuring stable voltage regulation
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual polarity or split supplies
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in low-power electronic assemblies

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details and reel specifications. Ensure that the procurement channel sources components directly from authorized distributors to maintain traceability and compliance with RoHS directives. Cross-reference the part number with the latest datasheet revision to validate current availability status.

Selection Notes

Select this component when a dual Zener array is required in a compact SOT-23 footprint. The 12 V nominal rating suits applications needing precise voltage clamping with tight tolerance requirements. Consider the thermal resistance and power dissipation limits when designing PCB layouts to ensure reliable operation under continuous load conditions.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V, all graded according to the international E24 standard. The G3 designation indicates a green, commercial grade product compliant with material categorization standards.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, dual common cathode configuration, and 12 V nominal voltage. Verify that alternative parts meet the same ±5 % tolerance and electrical parameters. Check for equivalent thermal ratings and ESD capabilities to ensure functional compatibility in existing designs.
