DZ23C9V1-HE3_A-08

Overview

The DZ23C9V1-HE3_A-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 9.1 V with a standard tolerance of ±5%. The device is AEC-Q101 qualified for automotive applications and features a maximum power dissipation of 300 mW on an FR-4 board. Electrical characteristics include a reverse leakage current of 100 nA 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
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant HE3_A material category

Applications

• Automotive voltage regulation circuits
• General-purpose voltage reference applications
• Protection against electrostatic discharge events

Procurement Notes

Verify the specific ordering suffix to confirm the reel size and minimum order quantity requirements. Ensure that the procurement documentation explicitly states AEC-Q101 qualification status. Confirm RoHS compliance details match the HE3_A designation before finalizing orders.

Selection Notes

Select this component when a 9.1 V Zener voltage is required in an SOT-23 footprint. Verify that the 300 mW power dissipation rating meets the thermal requirements of the target application. Ensure the ±5% voltage tolerance aligns with the circuit design specifications.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of Zener voltages from 2.2 V to 75 V. The HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance.

Replacement Considerations

Direct replacements must match the 9.1 V Zener voltage, SOT-23 package, and AEC-Q101 qualification. Verify equivalent power dissipation and dynamic resistance values to ensure circuit compatibility.
