Overview
The DZ23C5V6-HE3_A-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 5.6 V with a ±5 % tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 1 µA and a dynamic resistance of 40 Ω. Qualified to AEC-Q101 standards, it supports an operating temperature range from -55 °C to +150 °C and offers 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 with material categorization compliance.
Applications
- Automotive electronic circuits requiring robust voltage regulation.
- General-purpose voltage reference applications.
- Protection against overvoltage transients in sensitive signal lines.
Procurement Notes
Verify the specific ordering suffix matches the required reel size and qualification level. Confirm that the HE3_A designation aligns with project specifications for AEC-Q101 compliance. Ensure the component meets all environmental and RoHS requirements before finalizing procurement orders.
Selection Notes
Select this component when a 5.6 V Zener voltage with 5 % tolerance is required in an SOT-23 footprint. Consider the 5 mA test current and 40 Ω dynamic resistance for circuit design accuracy. Verify thermal management needs against the specified junction-to-lead thermal resistance values.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide Zener voltage range from 2.2 V to 75 V. The HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance, distinguishing it from commercial grade variants.
Replacement Considerations
Direct replacements within the same series include other DZ23C5V6 variants such as DZ23C5V6-E3-08 or DZ23C5V6-HE3-08, provided AEC-Q101 qualification is not strictly required. Cross-manufacturer equivalents must be verified for pinout compatibility and electrical parameter matching.
FAQ
What is the ESD protection rating for the DZ23C5V6-HE3_A-08?
The device provides ESD protection greater than 8 kV according to the human body model and greater than 800 V according to the machine model, as defined by AEC-Q101.
What is the maximum power dissipation on an FR-4 board?
When mounted on an FR-4 board with the recommended soldering footprint, the maximum power dissipation is 300 mW.
Does the HE3_A suffix indicate a different electrical function than the base part number?
No, the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance but does not change the fundamental electrical characteristics or function of the Zener diode compared to the base DZ23C5V6 specification.
