The Vishay DZ23C39-HE3-18 is a silicon planar Zener diode in the DZ23 series, housed in an SOT-23 package. It provides a nominal Zener voltage of 39 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum reverse leakage current of 0.05 µA at 46 V. Dynamic resistance is specified at 87 Ω (at IZT) and 300 Ω (at IK). It is AEC-Q101 qualified for automotive applications, supports a junction temperature up to 150 °C, and has a power dissipation rating of 300 mW on an FR-4 board.
Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 qualification and RoHS compliance. Ensure the trailing -18 indicates the 10,000-unit reel packaging format. Cross-reference the specific datasheet revision against the manufacturer's official documentation to validate electrical parameters before finalizing procurement orders.
Select this component when a 39 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Confirm that the 2 mA test current aligns with the target circuit design. Verify that the 300 mW power dissipation limit on an FR-4 board meets the thermal management requirements of the intended application environment.
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V using E24 grading standards. The DZ23C39 variant specifically targets the 39 V segment within this standardized lineup, offering consistent performance characteristics across the broader family.
Direct replacements include other Vishay DZ23 series parts such as DZ23C39-E3-18 or DZ23C39-HE3_A-18. Verify that substitute components maintain identical package dimensions, pin configurations, and electrical tolerances to ensure seamless integration without requiring PCB layout modifications.
The dynamic resistance (ZZ) is specified at 87 Ω when tested at the rated test current of 2 mA.
Yes, the HE3 suffix indicates that the device is AEC-Q101 qualified for automotive use.
The maximum reverse leakage current is 0.05 µA when measured at a reverse voltage of 46 V.
