Overview
The DZ23C39-HE3_A-08 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 39 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and provides a maximum dynamic resistance of 87 Ω. Electrical characteristics include a reverse leakage current of 50 μA at 29 V and a temperature coefficient ranging from 10 to 1 × 10⁻⁴/°C. It is AEC-Q101 qualified for automotive applications and supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant construction with HE3_A suffix designation
Applications
- Automotive electronic circuit voltage regulation
- General-purpose voltage reference stabilization
- Overvoltage protection in low-power signal lines
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the specific ordering code matches the required AEC-Q101 qualification status and tape-and-reel packaging specifications. Ensure compliance with RoHS directives and material categorization standards before integration into production workflows.
Selection Notes
Select this component when a precise 39 V reference is needed within a compact SOT-23 footprint. Consider the 2 mA test current requirement for biasing circuits. Evaluate the thermal resistance parameters against the expected ambient temperature conditions to ensure power dissipation limits are not exceeded during continuous operation.
Part Context
This part belongs to the DZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V. The HE3_A suffix specifically denotes the AEC-Q101 qualified variant packaged in taped units per reel, distinguishing it from commercial grade E3 versions.

FAQ
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is 300 mW when mounted on an FR-4 board using the recommended soldering footprint.
Does the HE3_A suffix indicate a different electrical function than the E3 suffix?
No, both variants share identical electrical characteristics; the suffix only indicates AEC-Q101 qualification and RoHS compliance status.
What is the specified ESD protection level?
The device provides ESD capability greater than 8 kV according to the human body model and greater than 800 V according to the machine model.
