Overview
The DZ23C20-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 20 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 50 Ω at this current level. Reverse leakage current is limited to 50 nA at a reverse voltage of 19 V. The component supports an operating temperature range from -55 °C to +150 °C and offers ESD protection exceeding 8 kV via the human body model.
Feature Summary
- Silicon planar construction for reliable voltage regulation
- High electrostatic discharge robustness per AEC-Q101 standards
- Green commercial grade material composition
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in electronic systems
- Clamping applications within signal processing paths
Procurement Notes
Verify the specific ordering code suffix against project requirements to ensure correct packaging configuration. Confirm that the standard ±5 % voltage tolerance aligns with circuit design specifications before finalizing procurement orders.
Selection Notes
Select this component when a 20 V reference is required in a compact SOT-23 footprint. Ensure the application current remains near the 5 mA test point to maintain specified impedance characteristics. Verify thermal management capabilities if power dissipation approaches the 300 mW limit on FR-4 substrates.
Part Context
This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V using the international E24 grading standard. All devices share the same SOT-23 physical dimensions and mounting style.
Replacement Considerations
Cross-reference other manufacturers offering Zener diodes in the SOT-23 package with a 20 V nominal rating and ±5 % tolerance. Verify that alternative components meet or exceed the 50 Ω dynamic resistance and 50 nA leakage current specifications.
FAQ
What is the marking code for the DZ23C20-G3-18?
The device marking code is V62.
Does the DZ23C20-G3-18 have AEC-Q101 qualification?
No, the G3-18 variant is not AEC-Q101 qualified; this qualification is available only upon request for specific part numbers.
What is the typical temperature coefficient for this voltage?
The temperature coefficient ranges from 8 to 10 x 10^-4 /°C at the 5 mA test current.
