Overview
The DZ23C20-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 20 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.05 μA at 19 V. Dynamic resistance is specified at 50 Ω (at IZT1) and 220 Ω (at IZT2). Power dissipation reaches 500 mW on lead-mounted configurations and 300 mW on FR-4 boards. Operating temperature ranges from -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for stable voltage regulation
- E24 standard grading with ±5 % voltage tolerance
- ESD protection exceeding 8 kV HBM and 800 V MM per AEC-Q101
Applications
- Voltage reference circuits requiring stable DC levels
- Over-voltage protection stages in signal paths
- Clamping applications in low-power electronic systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm RoHS compliance status through the provided datasheet or vendor certification. Ensure ordering suffixes match required packaging formats before finalizing procurement orders.
Selection Notes
Select this component when a 20 V Zener reference is needed in a compact SOT-23 footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the 5 mA test current aligns with the target circuit's biasing requirements.
Part Context
This device 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 form factor. The E3 suffix indicates RoHS-compliant commercial grade materials.
Replacement Considerations
Direct substitutes within the same series include DZ23C18-E3-08 and DZ23C22-E3-08. Cross-brand replacements require matching the 20 V nominal voltage, SOT-23 package, and 300 mW power rating on FR-4 substrates.
FAQ
What is the dynamic resistance of the DZ23C20-E3-08?
The dynamic resistance is 50 Ω at the test current IZT1 (5 mA) and 220 Ω at IZT2.
Does the DZ23C20-E3-08 have AEC-Q101 qualification?
No, the base P/N-E3 version is commercial grade. AEC-Q101 qualification is available only in the HE3_A variant.
