Overview
The DZ23C16-HE3_A-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 16 V with a ±5% tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 0.05 μA at 12 V and a dynamic resistance of 40 Ω at 5 mA. It is AEC-Q101 qualified for automotive applications, offering an ESD capability exceeding 8 kV (HBM) and 800 V (MM). Power dissipation is rated at 500 mW on FR-4 boards, with an operating temperature range of -55 °C to +150 °C.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- High electrostatic discharge protection exceeding 8 kV HBM
- RoHS-compliant construction with lead-free soldering compatibility
Applications
- Automotive electronic circuit voltage regulation
- General-purpose voltage reference circuits
- Overvoltage protection in low-power systems
Procurement Notes
Verify that the ordering suffix HE3_A confirms AEC-Q101 qualification and RoHS compliance as specified by the manufacturer. Confirm the -18 suffix corresponds to the standard 10,000-unit reel packaging format. Ensure the component meets specific automotive environmental requirements before final procurement.
Selection Notes
Select this component when a 16 V reference with tight 5% tolerance is required in a compact SOT-23 footprint. The HE3_A variant is necessary for applications demanding AEC-Q101 certification. Verify that the 40 Ω dynamic resistance and 0.05 μA leakage meet the specific circuit constraints.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of graded voltages from 2.2 V to 75 V within the same SOT-23 package family, allowing for standardized inventory management across different voltage requirements.
Replacement Considerations
Direct replacements include other DZ23C16 variants such as DZ23C16-E3-18 or DZ23C16-HE3_A-08, provided the packaging format matches the assembly line requirements. Cross-manufacturer equivalents must be verified against the 16 V nominal voltage and SOT-23 pinout.
