Overview
The DZ23C33-HE3-18 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 33 V with a ±5% tolerance and operates at a test current of 2 mA. The device has a maximum dynamic resistance of 80 Ω and a reverse leakage current of 50 μA at 25 V. It is AEC-Q101 qualified for automotive applications, supports a junction temperature up to 150 °C, and provides ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements.
- High electrostatic discharge (ESD) capability per AEC-Q101 standards.
- RoHS-compliant construction utilizing advanced planar technology.
Applications
- Automotive electronic circuit voltage regulation.
- General-purpose voltage reference applications.
- Protection against overvoltage transients in sensitive circuits.
Procurement Notes
Verify that the ordering suffix matches the required tape-and-reel packaging configuration. Confirm the specific HE3 variant designation aligns with project material compliance requirements. Ensure the component meets the necessary automotive qualification standards before finalizing procurement specifications.
Selection Notes
Select this component when a 33 V Zener voltage with tight tolerance is required in a compact SOT-23 footprint. Consider the AEC-Q101 qualification if the application involves automotive environments. Evaluate the thermal dissipation characteristics against the expected operating conditions to ensure reliable performance within the specified temperature range.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers a wide range of standard Zener voltages graded according to the international E24 standard. All devices share the same SOT-23 package dimensions and utilize silicon planar technology for consistent electrical performance across the product line.
Replacement Considerations
Direct replacements include other DZ23 series variants with identical voltage ratings but different packaging suffixes, such as DZ23C33-E3-18 or DZ23C33-HE3-08. Cross-brand equivalents must be verified against the specific electrical parameters and physical dimensions to ensure compatibility.
