DZ23C13-HE3_A-18

Overview

The DZ23C13-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 13 V with a tolerance of ±5 %. The device operates within a test current range of 1 to 5 mA and exhibits a dynamic resistance of up to 25 Ω at IZT1. Electrical characteristics include a maximum reverse leakage current of 0.1 μA at VR = 10 V and a temperature coefficient ranging from 7 to 9 × 10⁻⁴/°C. It supports power dissipation up to 500 mW (junction-to-lead) or 300 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
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant construction with material categorization compliance

Applications

• Automotive electronic circuits requiring AEC-Q101 qualification
• Voltage reference applications utilizing stable Zener breakdown characteristics
• Transient voltage suppression in low-power signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure packaging specifications match the required reel format for automated assembly processes.

Selection Notes

Select this component when a 13 V Zener reference is required in an SOT-23 footprint with automotive-grade reliability. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the 25 Ω dynamic resistance meets the noise and regulation requirements of the target circuit design.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide voltage range from 2.2 V to 75 V in a compact SOT-23 package. The HE3_A variant specifically denotes AEC-Q101 qualification, distinguishing it from the commercial grade E3 variants within the same physical form factor.

Replacement Considerations

Direct substitutes within the DZ23 series include other voltage ratings such as DZ23C12-HE3_A-18 or DZ23C15-HE3_A-18 if voltage adjustment is permissible. Cross-manufacturer equivalents must be verified for matching pinout, thermal resistance, and AEC-Q101 certification status.
