Overview
The Vishay DZ23C8V2-HE3-18 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 8.2 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 0.1 µA at 1 V. Dynamic resistance is specified at 7 Ω (at IZT1) and 50 Ω (at IZT2). It is AEC-Q101 qualified, RoHS-compliant, and rated for a junction temperature up to 150 °C.
Feature Summary
- AEC-Q101 automotive qualification with high ESD protection capability exceeding 8 kV via human body model and 800 V via machine model.
- Silicon planar construction ensuring stable voltage regulation across a wide operating temperature range from -55 °C to +150 °C.
- RoHS-compliant HE3 technology offering improved thermal performance and environmental compliance compared to standard commercial grades.
Applications
- Voltage reference circuits requiring precise 8.2 V levels in automotive electronics.
- Clamping and protection stages for sensitive input lines subject to electrostatic discharge events.
- Biasing networks in small-signal processing applications within constrained PCB spaces.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm AEC-Q101 qualification status. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the reel packaging matches the required tape-and-reel specifications for automated assembly processes.
Selection Notes
Select this component when an 8.2 V Zener voltage with tight ±5 % tolerance is required in an SOT-23 footprint. Consider the 5 mA test current and low leakage characteristics for precision applications. Verify that the thermal resistance and power dissipation limits align with the ambient temperature conditions of the target circuit design.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a broad voltage range from 2.2 V to 75 V, utilizing the SOT-23 package for compact surface-mount implementations. The DZ23C8V2 variant specifically targets the 8.2 V segment of the E24 standard voltage grading.
Replacement Considerations
Direct replacements within the same family include other DZ23 series variants with different voltage ratings but identical SOT-23 packaging and electrical characteristics. Cross-brand equivalents must match the 8.2 V nominal voltage, ±5 % tolerance, and SOT-23-3 pinout configuration.
