DZ23C3V6-G3-18

Overview

The DZ23C3V6-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 3.6 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 90 Ω at this current level. Electrical characteristics include a reverse leakage current of 5 μA maximum at 1 V, and a temperature coefficient ranging from -8 to -3 x 10⁻⁴/°C. The component supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable small-signal regulation
• Graded according to international E24 standard voltage values
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable low-voltage rails
• Clamping applications for signal lines
• Protection against electrostatic discharge events

Procurement Notes

Verify the specific ordering code suffix to confirm packaging quantity. The '-18' designation indicates units are supplied on a 13-inch reel containing 10,000 pieces. Confirm compliance requirements such as RoHS status and material categorization directly through official Vishay documentation channels before finalizing procurement orders.

Selection Notes

Select this component when a precise 3.6 V reference is required within a compact SOT-23 footprint. Ensure the circuit design accommodates the specified 5 mA test current for accurate voltage regulation. Evaluate the thermal management strategy, as power dissipation capabilities vary significantly between free-air conditions and mounted configurations on FR-4 substrates.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series encompasses a wide range of voltages from 2.2 V to 75 V, all utilizing the same SOT-23 package format. The 'G3' suffix denotes green commercial grade materials compliant with environmental directives.

Replacement Considerations

Direct replacements within the same family include other DZ23-G series variants with different voltage ratings but identical packaging. Cross-referencing requires matching the SOT-23-3 pinout configuration and ensuring equivalent electrical parameters such as dynamic resistance and leakage current are met for the specific application.
