Overview
The DZ23C24-E3-08 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 24 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 50 nA at 16.8 V. Dynamic resistance is specified at 70 Ω at the test current. Power dissipation reaches 500 mW when mounted on a board with recommended soldering footprints. Operating temperature ranges from -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable small-signal regulation
- Graded according to international E24 standard voltage values
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring stable low-voltage rails
- Overvoltage protection for sensitive electronic components
- Clamping applications in signal processing paths
Procurement Notes
Verify that the ordering code matches the commercial grade specification without AEC-Q101 qualification. Confirm the tape and reel packaging corresponds to the 3000 units per reel format. Ensure compliance requirements align with RoHS standards before finalizing procurement orders.
Selection Notes
Select this component when a 24 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 5 mA test current and 70 Ω dynamic resistance for circuit design accuracy. Evaluate thermal management needs against the 500 mW dissipation limit on FR-4 boards.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V. All devices share the same SOT-23 package dimensions and general electrical characteristics structure, differing primarily in their specific graded Zener voltage values.
Replacement Considerations
Direct substitutes within the same series include other DZ23 variants with different voltage ratings. Cross-manufacturer replacements must match the SOT-23 package, 24 V nominal voltage, and ±5 % tolerance specifications.
