DZ23C30-G3-08

Overview

The DZ23C30-G3-08 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 voltage regulation elements with a nominal Zener voltage of 30 V and a tolerance of ±5 %. The device operates at a test current of 2 mA and dissipates up to 300 mW on an FR-4 board. Key electrical characteristics include a dynamic resistance of 80 Ω and a reverse leakage current of 50 μA at 7 V. It supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

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

Applications

• Voltage reference circuits requiring dual regulated rails
• Overvoltage protection for sensitive signal lines
• Clamping applications in low-power consumer electronics

Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-08' designation indicates standard commercial grade packaging on an 8 mm tape reel. Confirm RoHS compliance status and material categorization details directly with the manufacturer or authorized distributors prior to finalizing procurement orders.

Selection Notes

Select this component when a dual-channel voltage regulator is required within a minimal footprint. Ensure the application current does not exceed the 2 mA test current threshold for optimal accuracy. Verify that the thermal dissipation constraints on the PCB allow for the specified 300 mW power rating under maximum ambient conditions.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades according to the E24 standard, all packaged in the space-saving SOT-23 form factor suitable for automated surface mount assembly processes.

Replacement Considerations

Direct substitutes within the same family include other DZ23C variants with different Zener voltages but identical pinouts and configurations. Cross-brand replacements must match the SOT-23-3 package dimensions, dual common cathode topology, and equivalent 300 mW power dissipation capabilities.
