Overview
The Vishay DZ23C30-HE3-08 is a dual silicon planar Zener diode in an SOT-23 package, configured as common cathode. It features a nominal Zener voltage of 30 V with a ±5% tolerance and operates at a test current of 2 mA. The device has a maximum reverse leakage current of 50 µA at 31.5 V and a dynamic resistance of 80 Ω at the test current. It is AEC-Q101 qualified for automotive applications, supports an operating temperature range from -55 °C to +150 °C, and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual silicon planar Zener diodes integrated in a single common cathode configuration
- AEC-Q101 qualified for automotive electronics reliability standards
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- Voltage reference and regulation in surface mount designs
- Clamping and protection in low-voltage signal lines
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm AEC-Q101 qualification status. Ensure that the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm RoHS compliance requirements align with the HE3 series designation before finalizing orders.
Selection Notes
Select this component when a dual Zener configuration with common cathode topology is required within a compact SOT-23 footprint. The 30 V nominal rating and ±5% tolerance suit precision voltage reference applications. Verify thermal management capabilities based on the 300 mW dissipation limit on standard FR-4 substrates during circuit design.
Part Context
This part belongs to the Vishay DZ23 Series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The HE3 variant specifically denotes RoHS compliance combined with AEC-Q101 automotive qualification, distinguishing it from the commercial grade E3 variants.
Replacement Considerations
Cross-reference with other manufacturers offering dual common cathode Zener diodes in SOT-23 packages. Verify matching electrical parameters such as Zener voltage tolerance, dynamic resistance, and power dissipation limits to ensure functional compatibility without redesigning the PCB layout.
