DZ23C6V2-E3-18

Overview

The DZ23C6V2-E3-18 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 6.2 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 10 Ω. Electrical characteristics include a reverse leakage current of 1 μA at 5 V and a temperature coefficient ranging from -1 to +7 x 10⁻⁴/°C. It supports power dissipation up to 500 mW on leads and 300 mW on FR-4 boards, functioning within a temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• Graded according to international E24 standard with ±5 % tolerance
• ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant commercial grade configuration

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required reel size, as the -18 designation indicates units supplied in 10,000-unit quantities on 13-inch reels. Confirm RoHS compliance status aligns with project requirements, noting that this specific base part number represents the commercial grade variant without AEC-Q101 automotive qualification. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with current manufacturing standards.

Selection Notes

Select this component when a precise 6.2 V regulation point is needed in space-constrained designs utilizing the SOT-23 footprint. Ensure the application current remains near the specified 5 mA test condition to maintain accuracy within the ±5 % tolerance band. Evaluate thermal management requirements if operating near the upper limits of the junction temperature range or if power dissipation exceeds 300 mW on standard PCB footprints.

Part Context

This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of voltages from 2.2 V to 75 V, all sharing the same compact SOT-23 package and standardized electrical testing parameters. The DZ23C6V2-E3-18 specifically targets the 6.2 V segment of the E24 voltage grading scale.

Replacement Considerations

Direct substitutes within the same series include other DZ23 variants with different voltage ratings but identical packaging and electrical profiles. For equivalent performance in SOT-23 packages, verify cross-references with other manufacturers offering 6.2 V Zener diodes with matching ±5 % tolerance and similar dynamic resistance specifications.
