DZ23C12-G3-08

Overview

The Vishay DZ23C12-G3-08 is a silicon planar Zener diode from the DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 12 V with a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and features a maximum power dissipation of 300 mW on an FR-4 board. Electrical characteristics include a test current of 5 mA, a reverse leakage current of 0.1 µA at 8 V, and a dynamic resistance of 20 Ω.

Feature Summary

• Utilizes silicon planar technology for robust performance
• Configured as a dual-element common cathode structure
• Compliant with AEC-Q101 qualification standards

Applications

• Voltage reference circuits requiring stable DC levels
• Protection against electrostatic discharge events

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 86341 and revision 1.2. Confirm that the ordering code matches the specific voltage and tolerance requirements. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.

Selection Notes

Select this component when a 12 V reference with ±5 % accuracy is required in a compact SOT-23 footprint. Consider the 300 mW thermal dissipation limit on FR-4 substrates during circuit design. Verify that the operating environment remains within the specified -55 °C to +150 °C temperature range for reliable operation.

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, utilizing the E24 grading standard. The G3 suffix indicates a green, commercial-grade product compliant with environmental regulations.

Replacement Considerations

Direct replacements must match the 12 V nominal voltage, ±5 % tolerance, and SOT-23-3 package. Verify equivalent thermal resistance and power dissipation capabilities. Check for identical marking codes and electrical parameters such as dynamic resistance and leakage current.
