DZ23C43-E3-08

Overview

The DZ23C43-E3-08 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 at a test current of 2 mA and features a maximum reverse leakage current of 50 µA at 32 V. Dynamic resistance is specified at 97 Ω at the test current. It supports a continuous power dissipation of 300 mW on an FR-4 board and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• ESD protection capability exceeding 8 kV via human body model
• RoHS-compliant commercial grade material categorization

Applications

• Voltage reference circuits requiring stable bias points
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in low-power electronic assemblies

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 86346 and revision 1.2 against official Vishay channels. Confirm that the ordering code matches the specific voltage grading and tape reel configuration required for the intended manufacturing process.

Selection Notes

Select this component when a 43 V regulation point is necessary within a compact SOT-23 footprint. Ensure the application current remains near the 2 mA test condition to maintain the specified ±5 % tolerance. Evaluate thermal constraints if operating near the upper limit of the 300 mW dissipation rating.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, utilizing standardized E24 grading. The base product line offers RoHS compliance for general commercial electronics applications.

Replacement Considerations

Direct substitutes within the same series include other DZ23C variants sharing the identical SOT-23 package and electrical characteristics. Cross-brand replacements require matching the 43 V nominal voltage, ±5 % tolerance, and 300 mW power dissipation limits.
