Overview
The DZ23C3V0-E3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 3.0 V with a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and provides a maximum power dissipation of 300 mW on an FR-4 board. Electrical characteristics include a reverse leakage current of 10 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA.
Feature Summary
- Dual-element common cathode configuration for space-efficient circuit designs
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant commercial grade construction without halogenated materials
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping applications for transient voltage suppression
- General-purpose signal conditioning in consumer electronics
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 standards before finalizing procurement orders.
Selection Notes
Select this component when a precise 3.0 V reference is needed in a compact SOT-23 footprint. Consider the 95 Ω dynamic resistance for impedance matching requirements. Verify thermal management capabilities if operating near the upper limit of the specified junction temperature range.
Part Context
This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltages graded according to the E24 standard. All variants share the same physical dimensions and electrical testing conditions defined in the official datasheet.
Replacement Considerations
Direct substitutes within the same series include other DZ23C3V0 variants such as DZ23C3V0-E3-18 or DZ23C3V0-HE3_A-08, which differ primarily in reel packaging or automotive qualification status.
FAQ
What is the marking code for the DZ23C3V0?
The marking code for the DZ23C3V0 is V42.
Is the DZ23C3V0-E3-08 AEC-Q101 qualified?
No, the base P/N-E3 designation indicates a commercial grade product. Automotive qualification requires the HE3_A suffix.
What is the typical temperature coefficient for this voltage?
The temperature coefficient ranges from -9 to -3 x 10^-4 /°C depending on the specific manufacturing bin.
