DZ23C3V0-E3-18

Overview

The DZ23C3V0-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 3.0 V with a ±5% tolerance and a test current of 5 mA. The device has a maximum reverse leakage current of 10 μA at 1 V and a dynamic resistance of 95 Ω at the test current. It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. The component is RoHS-compliant, commercial grade, and supplied in reels of 10,000 units.

Feature Summary

• Dual-element common cathode configuration for space-efficient circuit designs
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• Graded Zener voltages aligned with international E24 standards

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Clamping applications for transient voltage suppression
• General-purpose signal conditioning in consumer electronics

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm reel quantity and packaging format. Ensure that the required AEC-Q101 qualification status matches the application needs, as standard commercial grades do not include this automotive certification by default. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance with regional environmental regulations.

Selection Notes

Select this component when a precise 3.0 V reference is needed in a compact SOT-23 footprint. Consider the 95 Ω dynamic resistance for impedance matching requirements in the target circuit. Evaluate the thermal dissipation limits relative to the expected ambient operating conditions to ensure reliable performance within the specified junction temperature range.

Part Context

This device belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers a wide range of nominal voltages from 2.2 V to 75 V, all sharing the same SOT-23 package and general electrical characteristics. The 'E3' suffix indicates RoHS compliance, while the '-18' suffix specifies the 10,000-unit reel packaging format used for high-volume manufacturing integration.

Replacement Considerations

Direct substitutes within the same series include other DZ23 variants with different Zener voltages if the voltage requirement changes. For identical specifications, verify equivalent parts from other manufacturers that meet the SOT-23 form factor and 3.0 V ±5% tolerance criteria without altering the pinout or thermal characteristics.
