Overview
The Vishay DZ23C3V3-HE3-08 is a silicon planar Zener diode in the DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 3.3 V with a ±5% tolerance at a test current of 5 mA. The device features a maximum reverse leakage current of 5 µA and a dynamic resistance of 95 Ω. It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. The component is AEC-Q101 qualified for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- ESD protection exceeding 8 kV via human body model
- RoHS-compliant HE3 lead-free construction
Applications
- Automotive circuit voltage regulation
- General-purpose voltage reference circuits
- Overvoltage protection stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm AEC-Q101 qualification status. Ensure that the required tape-and-reel packaging matches the production line specifications. Cross-reference the exact part number with the latest Vishay datasheet revision to validate current availability and compliance details before finalizing procurement orders.
Selection Notes
Select this component when a precise 3.3 V reference is required in a compact SOT-23 footprint. The low dynamic resistance supports stable regulation under varying load conditions. Verify thermal management requirements, as power dissipation drops significantly above ambient temperatures. Confirm that the operating environment falls within the specified -55 °C to +150 °C range for reliable performance.
Part Context
This device belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers a wide range of standard E24 voltages from 2.2 V to 75 V. The HE3 suffix indicates RoHS-compliant, lead-free construction suitable for automotive environments. The base E3 variant lacks the automotive qualification found in the HE3 version.
Replacement Considerations
Direct replacements include other Vishay DZ23 series parts with identical voltage ratings. Verify pinout compatibility and thermal characteristics when substituting with components from different manufacturers.
