Overview
The DZ23C39-HE3-08 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 39 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum dynamic resistance of 87 Ω. Electrical characteristics include a reverse leakage current of 50 nA at 30 V and a temperature coefficient ranging from 10 to 1 × 10⁻⁴/°C. It supports an operating temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- ESD protection exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant construction utilizing HE3_A suffix technology
Applications
- Voltage reference circuits requiring stable bias points
- Overvoltage protection in automotive electronic modules
- Clamping applications in signal conditioning paths
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required AEC-Q101 qualification and RoHS compliance specifications. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines prior to soldering.
Selection Notes
Select this component when a 39 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 2 mA test current and 87 Ω dynamic resistance for circuit impedance matching. Verify thermal management capabilities against the 300 mW dissipation limit on standard PCB footprints.
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 the E24 grading standard. The specific HE3_A variant denotes AEC-Q101 qualification and RoHS compliance within the SOT-23 package family.
Replacement Considerations
Direct substitutes within the same manufacturer series include DZ23C39-HE3_A-18 for different reel packaging or DZ23C39-E3-08 for commercial grade applications without automotive qualification. Cross-manufacturer replacements must match the 39 V nominal voltage, SOT-23 package, and ±5 % tolerance.
