DZ23C30-E3-08

Overview

The DZ23C30-E3-08 is a dual silicon planar Zener diode in the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two independent elements per case. The nominal Zener voltage is 30 V with a standard tolerance of ±5 %. Electrical characteristics are defined at a test current (IZT1) of 2 mA, with a maximum reverse leakage current of 0.05 μA and a dynamic resistance (ZZK) of 250 Ω. The device supports a power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual silicon planar Zener diodes integrated into a single compact SOT-23 package
• Common cathode circuit configuration for simplified layout design
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant commercial grade construction without halogenated substances

Applications

• Voltage reference circuits requiring stable dual-channel regulation
• Clamping and protection stages in signal processing paths
• Biasing networks in low-power electronic assemblies

Procurement Notes

Verify that the ordering code matches the specific voltage variant and tape reel length required for production. Confirm RoHS compliance status and material categorization definitions against the manufacturer's official documentation before finalizing supply agreements.

Selection Notes

Select this component when a dual Zener solution in an SOT-23 footprint is necessary. Ensure the 30 V nominal rating aligns with the target circuit requirements. Verify thermal management capabilities based on the 300 mW dissipation limit on standard FR-4 substrates.

Part Context

This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers various voltage grades from 2.2 V to 75 V, all sharing the same physical package dimensions and general electrical testing standards. The E3 suffix indicates lead-free termination compliant with international environmental directives.

Replacement Considerations

Cross-reference with other manufacturers offering dual Zener diodes in SOT-23 packages. Verify pinout compatibility and ensure equivalent Zener voltage tolerances and thermal resistance values match the original design specifications.
