Overview
The DZ23C5V6-HE3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 5.6 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 1 µA at 38 V. Dynamic resistance is specified at 40 Ω under these conditions. It is AEC-Q101 qualified for automotive applications and supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- ESD protection exceeding 8 kV via human body model
- RoHS-compliant construction without halogenated additives
Applications
- Voltage reference circuits in automotive electronics
- Transient voltage suppression in low-power systems
- Biasing networks for small signal applications
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required tape-and-reel specifications and AEC-Q101 qualification status. Ensure compliance with RoHS directives and material categorization requirements before finalizing procurement orders.
Selection Notes
Select this component when a 5.6 V reference with ±5 % tolerance is required in an SOT-23 footprint. Consider the 40 Ω dynamic resistance and 1 µA leakage limits for circuit design. Verify thermal management capabilities against the 300 mW dissipation rating on FR-4 substrates.
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, all graded according to the international E24 standard. The HE3 suffix indicates AEC-Q101 qualification and RoHS compliance.
Replacement Considerations
Cross-reference with other DZ23 series variants for different voltage ratings. Verify pinout compatibility within the SOT-23 package. Check equivalent parts from other manufacturers only if they match the exact electrical parameters and AEC-Q101 qualification.
FAQ
What is the ESD capability of the DZ23C5V6-HE3-18?
The device offers ESD protection greater than 8 kV according to the human body model and greater than 800 V according to the machine model, as per AEC-Q101 standards.
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
Does the HE3 suffix indicate a functional difference compared to the base part number?
Yes, the HE3 suffix denotes that the component is AEC-Q101 qualified and RoHS-compliant, distinguishing it from the commercial grade base part number.
