DZ23C43-HE3-08

Overview

The DZ23C43-HE3-08 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 43 V with a standard tolerance of ±5%. The device operates within a temperature range of -55 °C to +150 °C and features AEC-Q101 qualification for automotive reliability. Electrical characteristics include a test current of 2 mA, a maximum reverse leakage current of 50 µA at 32 V, and a dynamic resistance of 97 Ω at the test current.

Feature Summary

• AEC-Q101 qualified for automotive applications
• Silicon planar construction for robust performance
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant HE3 lead-free termination

Applications

• Automotive electronic circuit voltage regulation
• General-purpose voltage reference circuits
• Overvoltage protection in signal lines

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required AEC-Q101 qualification status. Ensure compliance with RoHS directives and material categorization requirements before integration into production workflows.

Selection Notes

Select this component when a 43 V Zener reference is required in a compact SOT-23 footprint. Verify that the 2 mA test current aligns with the target circuit bias conditions. Consider the thermal resistance values if operating near the upper temperature limits or under high power dissipation scenarios.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V. The HE3 suffix indicates the use of Vishay's Green Molding compound and lead-free terminations, distinguishing it from commercial grade variants.

Replacement Considerations

Direct replacements must match the 43 V nominal voltage, ±5% tolerance, and SOT-23 package. Verify that substitute components meet the same AEC-Q101 automotive qualification standards and possess equivalent thermal and electrical ratings.
