Overview
The DZ23C15-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 15 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum power dissipation of 500 mW. It is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV via the human body model. Electrical characteristics include a reverse leakage current of 0.05 µA at 11 V, dynamic resistance of 30 Ω, and a temperature coefficient ranging from 7 to 9 x 10⁻⁴/°C.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant construction with HE3_A ordering suffix
Applications
- Voltage reference circuits requiring stable bias points
- Overvoltage protection for sensitive electronic components
- Clamping applications in automotive-grade systems
Procurement Notes
Verify that the specific part number includes the HE3_A suffix to confirm AEC-Q101 qualification status. Ensure the procurement order specifies the -18 tape and reel configuration, which corresponds to 10,000 units per 13-inch reel. Confirm compliance with RoHS directives as indicated by the base product designation.
Selection Notes
Select this component when a 15 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 5 mA test current and associated dynamic resistance for precision regulation needs. Verify thermal management capabilities against the specified junction-to-lead thermal resistance if operating near maximum power dissipation limits.
Part Context
This component 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 the international E24 standard grading. The DZ23C15 variant specifically addresses mid-range voltage stabilization needs within this standardized lineup.
Replacement Considerations
Direct replacements must match the 15 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify that alternative suppliers provide identical electrical parameters, particularly the dynamic resistance and leakage current specifications, to ensure circuit compatibility.
