DZ23C27-G3-08

Overview

The DZ23C27-G3-08 is a dual common cathode small signal Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 27 V with a tolerance of ±5 %. The device operates at a test current of 2 mA and features a dynamic resistance of 80 Ω at this current level. Electrical characteristics include a reverse leakage current of 0.05 μA at 19.5 V and a temperature coefficient ranging from 8 to 10 x 10⁻⁴/°C. Power dissipation is rated at 500 mW on lead-mounted conditions and 300 mW on FR-4 boards.

Feature Summary

• Dual common cathode configuration for space-efficient circuit designs
• Graded Zener voltages according to international E24 standard
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable DC levels
• Clamping applications for transient voltage suppression
• General-purpose voltage regulation in low-power electronics

Procurement Notes

Verify that the ordering code matches the specific voltage tolerance and tape reel quantity required for production. Confirm compliance with RoHS directives and material categorization standards before finalizing procurement orders. Ensure storage and handling procedures align with MSL level 1 requirements to prevent moisture damage during assembly.

Selection Notes

Select this component when a dual common cathode topology is necessary within a compact SOT-23 footprint. Verify that the operating current aligns with the 2 mA test condition to ensure accurate voltage regulation. Consider the thermal resistance values if the application involves high ambient temperatures or limited board space for heat dissipation.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of Zener voltages from 2.2 V to 75 V, all utilizing silicon planar technology. The G3 suffix indicates green commercial grade packaging compliant with environmental standards.

Replacement Considerations

Direct replacements must match the dual common cathode configuration and SOT-23 package dimensions. Verify that substitute components meet the same ±5 % voltage tolerance and power dissipation ratings under identical thermal conditions.
