DZ23C5V6-HE3-08

Overview

The Vishay DZ23C5V6-HE3-08 is a silicon planar Zener diode in the DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 5.6 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 1 µA at VR = 1 V. Dynamic resistance (ZZ) is specified at 40 Ω under these conditions. Power dissipation reaches 500 mW when mounted on an FR-4 board with the recommended footprint, while thermal resistance junction-to-lead is 250 K/W. The component supports an operating temperature range from -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 low-voltage rails
• Overvoltage protection in automotive electronics
• Clamping applications in signal conditioning paths

Procurement Notes

Verify that the HE3_A suffix indicates AEC-Q101 qualification status as defined by the manufacturer. Confirm the specific reel size and minimum order quantity requirements before placing orders. Ensure the procurement documentation matches the exact part number to avoid confusion with non-qualified variants or different packaging formats.

Selection Notes

Select this component when a 5.6 V reference is needed in a compact SOT-23 form factor. Consider the ±5 % tolerance and 40 Ω dynamic resistance for precision requirements. Evaluate the 500 mW power dissipation limit against expected thermal loads in the final assembly environment.

Part Context

This device 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. All members share the same SOT-23 package and general electrical characteristics structure, differing primarily in their specific breakdown voltage ratings.

Replacement Considerations

Direct substitutes within the same series include other DZ23C5Vx variants if voltage adjustments are acceptable. Cross-brand replacements must match the SOT-23 footprint, 5.6 V nominal voltage, and similar power dissipation limits.
