Overview
The DZ23C11-HE3_A-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 11 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 20 Ω. It is qualified to AEC-Q101 standards for automotive applications and offers ESD protection exceeding 8 kV via the human body model. The component supports a junction temperature up to 150 °C and is supplied in tape-and-reel packaging.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- High electrostatic discharge (ESD) robustness exceeding 8 kV HBM
- RoHS-compliant construction utilizing advanced HE3 technology
Applications
- Voltage reference circuits in automotive electronics
- Overvoltage protection stages for signal lines
- Clamping applications in compact surface-mount designs
Procurement Notes
Verify that the ordering suffix matches the required qualification level. The HE3_A designation confirms AEC-Q101 compliance and RoHS adherence. Confirm the -18 suffix aligns with the necessary reel quantity for automated assembly processes before finalizing procurement orders.
Selection Notes
Select this component when a precise 11 V reference is needed within a tight SOT-23 footprint. Ensure the circuit design accommodates the specified 5 mA test current for accurate voltage regulation. Verify that the thermal dissipation limits on the FR-4 board remain within the 300 mW threshold during operation.
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 using standard E24 grading. The specific HE3_A variant integrates Vishay's Green Package technology to enhance environmental compliance while maintaining high performance standards.
Replacement Considerations
Direct substitutes must match the 11 V nominal voltage, ±5 % tolerance, and SOT-23 package. Verify that any alternative component also meets AEC-Q101 automotive qualification if the application requires it. Cross-reference dynamic resistance and leakage current specifications to ensure functional equivalence.
