Overview
The DZ23C20-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 20 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and has a maximum dynamic resistance of 50 Ω at this current. Power dissipation is rated at 300 mW on an FR-4 board and 500 mW with leads clamped. The component supports an operating temperature range from -55 °C to +150 °C and includes ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- Silicon planar construction for reliable small-signal regulation.
- AEC-Q101 qualified versions available upon request.
- High electrostatic discharge robustness per automotive standards.
- Green commercial grade material categorization.
Applications
- Voltage reference circuits requiring stable low-power regulation.
- Protection against overvoltage transients in signal lines.
- Biasing networks in general-purpose electronic equipment.
Procurement Notes
Verify the specific ordering code suffix matches the required reel quantity. The '-08' suffix indicates a 3000-unit minimum order quantity on an 8 mm tape. Confirm RoHS compliance status and ensure the design accommodates the specified thermal resistance values for the target PCB footprint.
Selection Notes
Select this part when a 20 V Zener voltage with 5 % tolerance is required in a compact SOT-23 form factor. Ensure the circuit current does not exceed the 300 mW power dissipation limit on standard FR-4 substrates. Consider the AEC-Q101 qualified variants if automotive reliability standards are mandatory for the application environment.
Part Context
This component 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, all graded according to the international E24 standard. These devices are designed for general-purpose voltage regulation and transient suppression in consumer and industrial electronics.
Replacement Considerations
Direct substitutes within the same Vishay family include other DZ23-G series parts with different voltage ratings. Cross-brand replacements must match the SOT-23 package dimensions, 20 V nominal voltage, ±5 % tolerance, and equivalent power dissipation capabilities.
