Overview
The DZ23C3V9-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 3.9 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 3 µA at 1 V. Dynamic resistance is specified at 90 Ω (at IZT1) and 500 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
- Silicon planar construction for stable voltage regulation
- Dual common cathode configuration within a compact SOT-23 footprint
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring low-profile packaging
- Clamping applications for signal lines
- Protection stages against electrostatic discharge events
Procurement Notes
Verify that the ordering suffix matches the required reel specifications. Confirm RoHS compliance status aligns with project requirements. Ensure the component meets AEC-Q101 standards if automotive qualification is necessary. Validate datasheet revisions before finalizing procurement orders.
Selection Notes
Select this component when a dual common cathode arrangement is needed in a minimal footprint. Consider the specific dynamic resistance values for impedance matching. Evaluate thermal management capabilities based on the 500 mW dissipation limit. Verify operating temperature ranges against environmental conditions.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various graded voltages according to the E24 standard. The base product line includes both commercial grade and AEC-Q101 qualified variants.
Replacement Considerations
Direct substitutes include other DZ23 series parts with identical electrical characteristics but different voltage ratings or packaging options. Cross-referencing with equivalent dual common cathode Zener arrays in SOT-23 packages is recommended.
