Overview
The DZ23C27-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 27 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 20 V. Dynamic resistance is specified at a maximum of 80 Ω, while the temperature coefficient ranges between 8 and 10 x 10⁻⁴/°C. Power dissipation reaches 500 mW when mounted on an FR-4 board, supporting an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Utilizes silicon planar technology for stable voltage regulation within the E24 standard grading system.
- Features high electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model standards.
- Designed for compact surface-mount applications using the SOT-23 package configuration.
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in low-power electronic assemblies
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with RoHS directives and material categorization requirements before finalizing procurement orders.
Selection Notes
Select this component based on the specific 27 V requirement and the ±5 % tolerance constraint. Evaluate the thermal management needs against the 500 mW power dissipation limit at ambient conditions. Consider the 2 mA test current for circuit design compatibility and verify that the SOT-23 footprint aligns with the target PCB layout constraints.
Part Context
This device 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 tolerances across various packages. The DZ23C27 variant specifically addresses mid-range voltage regulation needs within this extensive product family.
Replacement Considerations
Direct substitutes include other Vishay parts within the DZ23 series or equivalent devices from different manufacturers meeting identical electrical parameters. Verify pinout compatibility and package dimensions to ensure seamless integration without modifying the existing circuit board design.
FAQ
