DZ23C5V6-G3-18

Overview

The Vishay DZ23C5V6-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 5.6 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 1 µA at the specified voltage. Dynamic resistance is limited to 40 Ω at the test current. It supports a continuous power dissipation of 300 mW on an FR-4 board and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation.
• Configured as a single common cathode unit in a compact SOT-23 footprint.
• Compliant with RoHS standards and characterized for commercial grade environments.

Applications

• Voltage reference circuits requiring precise potential levels.
• Overvoltage protection stages in signal processing paths.
• Clamping applications for transient suppression.

Procurement Notes

Verify the specific ordering code suffix against project requirements to ensure correct packaging quantities. Confirm that the standard commercial grade designation aligns with environmental constraints. Cross-reference the document number 86341 for the most recent electrical specifications before finalizing component selection.

Selection Notes

Select this component when a 5.6 V reference is needed in a small surface-mount form factor. Ensure the circuit design accommodates the 300 mW thermal limit on standard PCB layouts. Verify that the ±5 % voltage tolerance meets the system's accuracy requirements without additional calibration.

Part Context

This part belongs to the Vishay DZ23-G series of small signal Zener diodes. The series offers a wide range of graded voltages from 2.2 V to 75 V. All variants share the same SOT-23 package and general electrical characteristics, differing primarily in their specific breakdown voltage ratings.

Replacement Considerations

Direct replacements include other manufacturers' SOT-23 Zener diodes rated at 5.6 V with similar power dissipation. Verify pinout compatibility and dynamic resistance values to ensure equivalent performance in existing designs.
