Overview
The DZ23C4V3-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 4.3 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and has a maximum dynamic resistance of 90 Ω at this current. Electrical characteristics are specified over an operating temperature range of -55 °C to +150 °C. The component is supplied on a 13-inch reel containing 10,000 units per order.
Feature Summary
- Dual-element common cathode configuration within a compact SOT-23 footprint
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
- Green commercial grade construction compliant with RoHS standards
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 that the specific part number matches the required voltage tolerance and packaging format. Confirm compliance requirements against the latest Vishay material categorization documentation. Ensure ordering quantities align with the minimum reel size specifications provided by the manufacturer.
Selection Notes
Select this component when a dual Zener array in an SOT-23 package is required. Consider the thermal resistance values if power dissipation limits are critical. Verify that the operating temperature range meets the environmental conditions of the target application.
Part Context
This device belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded Zener voltages according to the E24 standard. The G3 suffix indicates green, commercial grade construction without halogenated flame retardants.
Replacement Considerations
Direct replacements must match the 4.3 V nominal voltage, 5% tolerance, and SOT-23-3 package. Verify equivalent dynamic resistance and leakage current specifications. Check for AEC-Q101 qualification if automotive reliability is required.
