Overview
The DZ23C10-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 10 V with a ±5 % tolerance and operates at a test current of 5 mA. The device has a maximum dynamic resistance of 15 Ω and a reverse leakage current of 0.1 μA at 7.5 V. It is AEC-Q101 qualified for automotive applications, offering an operating temperature range of -55 °C to +150 °C and a power dissipation of 300 mW on an FR-4 board.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant HE3_A material categorization
Applications
- Automotive voltage regulation circuits
- Reference voltage generation
- Overvoltage protection
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to confirm the tape-and-reel quantity and packaging format. Confirm that the HE3_A designation aligns with the required AEC-Q101 qualification status for your application before finalizing procurement.
Selection Notes
Select this component when a dual common cathode configuration is not required but standard single Zener characteristics are needed within an automotive-grade framework. Ensure the circuit design accommodates the specified 15 Ω dynamic resistance and 0.1 μA leakage limits at the intended operating temperature.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of graded Zener voltages from 2.2 V to 75 V, all utilizing the compact SOT-23 package suitable for space-constrained surface-mount designs.
Replacement Considerations
Direct substitutes include other DZ23C10 variants such as DZ23C10-E3-18 or DZ23C10-HE3-18, provided the specific AEC-Q101 qualification requirements match the system design constraints.
FAQ
What is the ESD capability of the DZ23C10-HE3_A-18?
The device offers an ESD capability of greater than 8 kV according to the human body model and greater than 800 V according to the machine model, as per AEC-Q101 standards.
How does the power dissipation change based on mounting conditions?
The total power dissipation is rated at 500 mW when the thermal resistance junction-to-lead is 250 K/W, and it reduces to 300 mW when mounted on an FR-4 board using the recommended soldering footprint.
What is the marking code for this specific part number?
The marking code for the DZ23C10 variant in the DZ23 series is V55.
