Overview
The DZ23C9V1-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 9.1 V with a standard tolerance of ±5%. The device operates within a temperature range of -55 °C to +150 °C and is qualified to AEC-Q101 standards for automotive applications. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 7 V and a dynamic resistance of 10 Ω at a test current of 5 mA.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD protection exceeding 8 kV via human body model
- RoHS-compliant construction with HE3_A ordering suffix
Applications
- Automotive electronic circuit protection
- Voltage reference stabilization
- Overvoltage clamping in signal lines
Procurement Notes
Verify that the specific HE3_A suffix confirms AEC-Q101 qualification status. Ensure the ordering code matches the required tape-and-reel packaging format. Confirm RoHS compliance documentation aligns with project regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when an AEC-Q101 qualified Zener diode is required for automotive designs. The SOT-23 package suits space-constrained PCB layouts. Verify that the 9.1 V nominal voltage and ±5% tolerance meet the specific circuit design parameters.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The HE3_A suffix specifically denotes RoHS compliance combined with AEC-Q101 qualification, distinguishing it from commercial grade variants.
Replacement Considerations
Direct replacements must match the 9.1 V Zener voltage, SOT-23 package, and AEC-Q101 qualification. Verify equivalent dynamic resistance and thermal characteristics to ensure circuit performance compatibility.
