DZ23C3V0-G3-18

Overview

The Vishay DZ23C3V0-G3-18 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 3.0 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 10 µA. Dynamic resistance is specified at 95 Ω under these conditions. Power dissipation reaches 500 mW when mounted on an FR-4 board with a recommended footprint, supporting an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Complies with international E24 standard grading for voltage tolerance
• Offers high electrostatic discharge protection capability

Applications

• Voltage reference circuits requiring precise low-voltage regulation
• Protection against electrostatic discharge in sensitive electronics
• Clamping applications within general-purpose electronic equipment

Procurement Notes

Verify that the ordering code matches the required tape configuration. Confirm compliance requirements such as RoHS status and material categorization before finalizing orders. Ensure the supplier provides documentation confirming the specific suffix designation for packaging quantity and reel size.

Selection Notes

Select this component when a 3.0 V reference is needed in a compact SOT-23 form factor. Consider the 500 mW power dissipation limit on FR-4 boards during thermal design. Verify that the ±5 % voltage tolerance aligns with circuit requirements, as tighter grades are available in other part numbers within the same series.

Part Context

This device 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, all utilizing the SOT-23 package. The G3 suffix indicates green, commercial grade construction compliant with environmental directives.

Replacement Considerations

Other parts in the DZ23-G series offer different voltage ratings but share identical packaging and electrical characteristics. Cross-referencing requires matching the specific Zener voltage and ensuring the dynamic resistance remains within acceptable limits for the target application.
