Overview
The DZ23C47-E3-08 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 47 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 50 μA at 40 V. Dynamic resistance is specified at 97 Ω (at IZT1) and 375 Ω (at IZT2). It supports a power dissipation of up to 500 mW and functions within a temperature range of -55 °C to +150 °C.
Feature Summary
- Utilizes silicon planar technology for robust voltage regulation
- Configured as a common cathode circuit arrangement
- Compliant with RoHS standards for commercial grade applications
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in signal paths
- Clamping applications for transient suppression
Procurement Notes
Verify that the specific part number matches the required voltage tolerance and thermal characteristics for your design. Confirm the packaging format corresponds to your assembly line requirements. Ensure compliance with local environmental regulations regarding material composition before finalizing procurement orders.
Selection Notes
Select this component when a 47 V reference is needed in a compact SOT-23 footprint. Consider the 2 mA test current requirement for biasing networks. Evaluate the dynamic resistance specifications against the noise sensitivity of the target application to ensure adequate performance stability.
Part Context
This component belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, offering standardized E24 grading. These devices are designed for general-purpose voltage regulation tasks in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other Vishay DZ23 series parts with identical voltage ratings, such as DZ23C47-E3-18. Cross-manufacturer replacements must match the SOT-23 package dimensions, 47 V nominal voltage, and equivalent electrical parameters like dynamic resistance and leakage current.
