DZ23C20-HE3_A-18

Overview

The DZ23C20-HE3_A-18 is a dual silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 20 V and a tolerance of ±5 %. The device operates at a test current of 5 mA, dissipates up to 300 mW on an FR-4 board, and withstands junction temperatures up to 150 °C. It is AEC-Q101 qualified for automotive applications and supplied in tape-and-reel packaging.

Feature Summary

• Dual silicon planar Zener diodes configured as a common cathode pair within a single SOT-23 package
• AEC-Q101 qualified for automotive reliability standards
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant construction utilizing lead-free soldering materials

Applications

• Automotive electronic circuits requiring voltage regulation
• General-purpose voltage reference applications
• Transient voltage suppression in low-power signal lines

Procurement Notes

Verify that the ordering suffix matches HE3_A-18 to confirm AEC-Q101 qualification and 10,000-unit reel packaging. Cross-reference the specific document number 86346 to ensure access to the latest electrical characteristics and mechanical dimensions before finalizing procurement specifications.

Selection Notes

Select this component when a dual Zener array with a 20 V nominal rating is required in a compact SOT-23 footprint. Ensure the application supports the specified 5 mA test current and 300 mW power dissipation limits on standard FR-4 substrates. Confirm that the ±5 % voltage tolerance aligns with the circuit design requirements.

Part Context

This part belongs to the Vishay DZ23 Series, which provides a range of dual surface mount Zener diodes. The series covers Zener voltages from 2.2 V to 75 V, graded according to the international E24 standard. All variants share the same SOT-23 package and thermal characteristics while offering different voltage options.

Replacement Considerations

Direct replacements must maintain the 20 V nominal voltage, ±5 % tolerance, and SOT-23 package. Verify that alternative components meet the same AEC-Q101 qualification and power dissipation ratings to ensure functional equivalence in existing designs.
