DZ23C3V6-HE3_A-18

Overview

The DZ23C3V6-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 3.6 V with a ±5% tolerance and operates at a test current of 5 mA. The device is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a maximum reverse leakage current of 5 µA at 1 V and a dynamic resistance of 90 Ω at 5 mA.

Feature Summary

• Automotive-grade reliability through AEC-Q101 qualification
• High electrostatic discharge robustness exceeding 8 kV human body model limits
• RoHS-compliant construction utilizing halogen-free materials

Applications

• Voltage reference circuits in automotive electronics
• ESD protection stages for sensitive signal lines
• Clamping applications in low-voltage DC power supplies

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the specific part number includes the HE3_A designation to ensure AEC-Q101 automotive qualification status. Cross-reference the manufacturer's latest documentation to validate RoHS compliance and material categorization before finalizing procurement orders.

Selection Notes

Select this component when a stable 3.6 V reference is required within an SOT-23 footprint. Ensure the application environment remains within the specified -55 °C to +150 °C operating range. Verify that the circuit design accommodates the 90 Ω dynamic resistance and 5 µA leakage current specifications under all expected operating conditions.

Part Context

This device belongs to the DZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of graded voltages according to the international E24 standard. The HE3_A variant specifically denotes the automotive-qualified version packaged in reels for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements must maintain the 3.6 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify that alternative components meet the same thermal resistance and ESD performance criteria to ensure compatibility with existing board layouts and system reliability standards.
