Overview
The DZ23C9V1-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 9.1 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.1 µA at 7 V. Dynamic resistance is specified at 10 Ω, with a temperature coefficient ranging from 5 to 8 x 10⁻⁴/°C. Power dissipation reaches 300 mW on an FR-4 board, supporting an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable voltage regulation
- ESD protection exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant commercial grade configuration
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping applications for transient voltage suppression
- General-purpose discrete semiconductor voltage control
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 packaging specifications. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.
Selection Notes
Select this component when a 9.1 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 5 mA test current and 10 Ω dynamic resistance for circuit stability. Verify thermal management requirements against the 300 mW dissipation limit on FR-4 substrates.
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, utilizing standardized E24 grading. The specific -E3-08 designation indicates a RoHS-compliant commercial grade unit packaged in 8 mm tape on a 7-inch reel.
Replacement Considerations
Direct parameter-equivalent replacements within the same Vishay family include DZ23C9V1-E3-18 (different reel size) and DZ23C9V1-G3-08. Cross-manufacturer equivalents require verification of matching voltage, power dissipation, and package dimensions.
