DZ23C5V1-E3-08

Overview

The DZ23C5V1-E3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and has a maximum reverse leakage current of 1 μA at 7 V. Dynamic resistance is specified at 60 Ω (max) at the test current. It supports a junction temperature up to 150 °C and offers ESD protection exceeding 8 kV via the human body model.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• High electrostatic discharge robustness per AEC-Q101 standards
• RoHS-compliant commercial grade material categorization

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Clamping applications in signal lines

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel size and minimum order quantity requirements. Ensure that the component selection aligns with the intended thermal dissipation conditions on the target printed circuit board footprint.

Selection Notes

Select this component when a precise 5.1 V reference is required within a compact surface-mount form factor. Consider the dynamic impedance and leakage specifications relative to the circuit's sensitivity. Verify that the operating ambient temperature remains within the specified range to maintain performance stability.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of standard Zener voltages graded according to the international E24 standard, all packaged in the space-efficient SOT-23 outline.

Replacement Considerations

Direct substitutes include other DZ23 series variants with identical electrical characteristics but different voltage ratings, such as DZ23C5V6-E3-08 or DZ23C4V7-E3-08. Cross-brand replacements must match the SOT-23 package dimensions and the 5.1 V nominal voltage specification.
