Overview
The DZ23C22-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 22 V with a ±5% tolerance and a test current of 5 mA. The device has a maximum reverse leakage current of 50 nA at 17 V and a dynamic resistance of 55 Ω. Rated for a power dissipation of 300 mW on FR-4 boards, it operates within a temperature range of -55 °C to +150 °C. The component complies with RoHS standards and utilizes a common cathode configuration.
Feature Summary
- Silicon planar construction with E24 standard grading
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant commercial grade material
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific ordering code suffix against project requirements. The '-08' suffix indicates a 3000-unit reel quantity on an 8 mm tape. Confirm that the base part number without qualification suffixes meets the necessary environmental or automotive standards if required by the design specifications.
Selection Notes
Select this component when a 22 V Zener voltage is required in a compact SOT-23 footprint. Ensure the circuit design accommodates the 55 Ω dynamic resistance and 50 nA leakage current limits. Verify thermal management capabilities, as power dissipation drops significantly above ambient temperatures due to the 250 K/W junction-to-lead thermal resistance.
Part Context
This part 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, all utilizing the same SOT-23 package format. The 'E3' designation confirms lead-free and RoHS compliance for general commercial electronics applications.
Replacement Considerations
Direct replacements include other DZ23 series variants with identical packaging but different voltages, such as DZ23C20-E3-08 or DZ23C24-E3-08. Cross-brand equivalents must match the SOT-23 pinout, 22 V nominal voltage, and ±5% tolerance.
