Overview
The DZ23C3V9-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 3.9 V with a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and features a maximum power dissipation of 500 mW when mounted on an FR-4 board with the recommended soldering footprint. Electrical characteristics include a test current of 5 mA, a maximum reverse leakage current of 3 µA at 1 V, and a dynamic resistance of 90 Ω measured at the test current.
Feature Summary
- Utilizes silicon planar technology for robust voltage regulation
- Complies with RoHS standards and material categorization requirements
- Offers high electrostatic discharge protection capability
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Protection against overvoltage transients in sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify that the specific ordering code matches the required tape and reel configuration. Confirm compliance with AEC-Q101 qualification if automotive-grade reliability is mandated for the target application environment.
Selection Notes
Select this component based on the precise 3.9 V nominal requirement and the ±5 % tolerance specification. Ensure the thermal management design accommodates the specified power dissipation limits under expected ambient operating conditions.
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, utilizing the compact SOT-23 package to support space-constrained printed circuit board layouts.
Replacement Considerations
Direct replacements within the same series include other voltage variants such as DZ23C3V6 or DZ23C4V3. Cross-manufacturer equivalents must be evaluated for matching package dimensions, electrical tolerances, and thermal characteristics.
FAQ
What is the ESD protection rating for this component?
The device meets AEC-Q101 ESD capability standards, offering greater than 8 kV protection via the human body model and greater than 800 V via the machine model.
How does the power dissipation change with mounting conditions?
The maximum power dissipation is rated at 500 mW on an FR-4 board with the recommended soldering footprint. Without this specific mounting condition, the rating may differ based on the thermal resistance parameters.
Is this component qualified for automotive applications?
The base P/N-E3 designation indicates commercial grade. For AEC-Q101 qualified versions suitable for automotive use, the HE3_A suffix should be selected instead.
