Overview
The DZ23C33-HE3_A-08 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 tolerance of ±5 %. The device operates within a temperature range of -55 °C to +150 °C and provides a maximum power dissipation of 300 mW on an FR-4 board. It is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements.
- High electrostatic discharge capability per AEC-Q101 standards.
- RoHS-compliant construction with HE3_A ordering suffix.
Applications
- Automotive electronic circuits requiring robust voltage regulation.
- General-purpose voltage reference applications.
- Protection against overvoltage transients in sensitive signal lines.
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance as documented in the official datasheet. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to maintain solderability and performance integrity upon installation.
Selection Notes
Select this component when a precise 33 V reference is required in space-constrained designs utilizing the SOT-23 footprint. Consider the 300 mW thermal limit on standard PCBs during circuit design. Verify that the ±5 % voltage tolerance aligns with the system's regulatory accuracy requirements before finalizing the bill of materials.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, graded according to the international E24 standard. The HE3_A variant specifically denotes the automotive-grade, RoHS-compliant version packaged in tape and reel format for automated assembly processes.
Replacement Considerations
Direct replacements must match the 33 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Cross-referencing should prioritize components with identical pinout configurations and comparable dynamic resistance characteristics to ensure circuit stability without redesign.
FAQ
What is the maximum power dissipation rating for the DZ23C33-HE3_A-08?
