Overview
The DZ23C12-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 12 V with a ±5% tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 0.1 µA at 9 V and a dynamic resistance of 20 Ω. Qualified to AEC-Q101 standards, it supports junction temperatures up to 150 °C and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements.
- Integrated electrostatic discharge protection rated above 8 kV via human body model.
- RoHS-compliant construction utilizing HE3_A technology.
Applications
- Voltage reference circuits in automotive electronics.
- ESD protection for signal lines requiring high-voltage withstand.
- Clamping applications in compact surface-mount designs.
Procurement Notes
Verify that the ordering suffix matches the required qualification level. The HE3_A designation confirms AEC-Q101 compliance, whereas other suffixes may indicate commercial grade. Confirm the specific tape-and-reel quantity aligns with production needs before finalizing orders.
Selection Notes
Select this component when a 12 V reference is needed in an SOT-23 footprint with automotive-grade certification. Ensure the circuit design accommodates the specified 5 mA test current and 20 Ω dynamic resistance. Verify thermal management capabilities against the 500 mW dissipation limit under expected operating conditions.
Part Context
This part belongs to the DZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series provides a range of voltages from 2.2 V to 75 V in the SOT-23 package. The DZ23C12 variant specifically targets the 12 V segment of the E24 standard grading.
Replacement Considerations
Direct replacements within the same family include DZ23C12-E3-08 or DZ23C12-HE3-08. Note that non-AEC variants lack automotive qualification. Cross-manufacturer equivalents require verification of pinout compatibility and electrical parameter alignment.
FAQ
What is the ESD protection rating for this component?
The device meets AEC-Q101 ESD capability requirements, offering protection greater than 8 kV using the human body model and greater than 800 V using the machine model.
How does the HE3_A suffix affect the component's specifications?
The HE3_A suffix indicates that the component is RoHS-compliant and qualified to the AEC-Q101 automotive standard, distinguishing it from commercial grade versions.
What is the maximum power dissipation on an FR-4 board?
When mounted on an FR-4 board with the recommended soldering footprint, the maximum power dissipation is limited to 300 mW.
