Overview
The DZ23C39-E3-18 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 39 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 0.05 µA at 38 V. Dynamic resistance is specified at 87 Ω (at IZT1) and 300 Ω (at IZT2). It supports a power dissipation of 300 mW on FR-4 boards and functions within a temperature range of -55 °C to +150 °C.
Feature Summary
- Utilizes silicon planar technology for stable voltage regulation
- Configured as a single common cathode unit in a compact SOT-23 footprint
- Compliant with RoHS standards for commercial grade applications
Applications
- Voltage reference circuits requiring precise low-voltage regulation
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in general-purpose electronic equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm reel specifications and minimum order quantities. Confirm that the component meets the required environmental compliance standards for the intended manufacturing process before finalizing procurement orders.
Selection Notes
Select this component when a 39 V Zener voltage is required in a small surface-mount form factor. Ensure the application circuit can accommodate the specified dynamic resistance and leakage current characteristics at the operating test current of 2 mA.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers a wide range of graded voltages according to the E24 standard, all packaged in the space-efficient SOT-23 configuration suitable for automated surface-mount assembly processes.
Replacement Considerations
Direct substitutes include other DZ23 series variants with identical packaging but different voltage ratings, such as DZ23C36-E3-18 or DZ23C43-E3-18. Cross-brand replacements must match the SOT-23 package, 300 mW power rating, and 39 V nominal voltage specifications.
