DZ23C3V3-E3-08

Overview

The DZ23C3V3-E3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 3.3 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 5 µA at 1 V. Dynamic resistance is specified at 95 Ω, while the temperature coefficient ranges from -8 to -3 x 10⁻⁴/°C. Power dissipation reaches 500 mW on lead-mounted configurations and 300 mW on FR-4 boards. Operating temperatures span from -55 °C to +150 °C.

Feature Summary

• Dual common cathode configuration within a compact three-terminal SOT-23 footprint
• Graded Zener voltages aligned with international E24 standards for design flexibility
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Clamping applications for transient voltage suppression
• Biasing networks in small signal processing stages

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm RoHS compliance status and ensure the ordering suffix matches the required reel quantity and tape specifications. Validate that the specific batch meets the intended environmental operating conditions before integration into final assemblies.

Selection Notes

Select this component when a precise 3.3 V reference is needed in space-constrained designs. The dual common cathode structure allows for independent or combined operation. Ensure thermal management aligns with the 300 mW dissipation limit on PCB footprints. Verify that the negative temperature coefficient suits the circuit's stability requirements across the full operating range.

Part Context

This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide voltage range from 2.2 V to 75 V in the same SOT-23 package family. The E3 suffix indicates RoHS compliance for commercial grade applications, distinguishing it from the HE3_A variant which includes AEC-Q101 automotive qualification.

Replacement Considerations

Direct substitutes include other DZ23 series variants with identical pinouts but different voltage ratings, such as DZ23C3V0-E3-08 or DZ23C3V6-E3-08. Cross-brand replacements must match the SOT-23-3 package dimensions, 3.3 V nominal voltage, and similar dynamic resistance characteristics to maintain circuit performance.
