DZ23C39-G3-08

Overview

The DZ23C39-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 39 V with a ±5% tolerance and operates at a test current of 2 mA. The device provides a maximum dynamic resistance of 87 Ohms and a reverse leakage current of 50 nA at 29 V. Rated for a power dissipation of 300 mW on an FR-4 board, it supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Complies with international E24 standard grading for voltage selection
• Offers high electrostatic discharge protection capability

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in signal conditioning paths
• Clamping applications within low-power electronic systems

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official manufacturer documentation. Confirm that the specific suffix matches the required tape and reel packaging configuration. Ensure compliance with RoHS directives and material categorization standards before finalizing acquisition.

Selection Notes

Select this component when a 39 V regulation point is required within a compact footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the 87 Ohm dynamic resistance meets the ripple rejection requirements of the target circuit design.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V using standardized E24 values. All devices share the same SOT-23 physical dimensions and thermal characteristics.

Replacement Considerations

Direct substitutes must match the 39 V nominal voltage, SOT-23 package, and 300 mW power rating. Verify that alternative components maintain equivalent dynamic resistance and leakage current specifications to ensure circuit stability.
