Overview
The DZ23C30-E3-18 is a dual silicon planar Zener diode in an SOT-23 package, configured as a common cathode array. It provides a nominal Zener voltage of 30 V with a tolerance of ±5 %. The device operates at a test current of 2 mA and features a maximum reverse leakage current of 0.05 µA at 24 V. Dynamic resistance is specified at 80 Ω (at Izt) and 250 Ω (at Izk). Power dissipation reaches 500 mW on FR-4 boards, with an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual silicon planar Zener diodes integrated into a single common cathode configuration
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant commercial grade construction without automotive qualification
Applications
- Voltage reference circuits requiring dual independent regulation channels
- Signal clamping applications for protecting sensitive input stages
- Overvoltage protection in surface mount electronic assemblies
Procurement Notes
Verify the specific ordering suffix against official Vishay documentation before procurement. The '-E3' designation indicates RoHS compliance and halogen-free status for commercial grade devices. Confirm that the '-18' suffix aligns with the required reel packaging quantity of 10,000 units per standard tape and reel specifications.
Selection Notes
Select this component when a dual-channel voltage regulation solution is required within a compact SOT-23 footprint. Ensure the application current does not exceed the 2 mA test current threshold for optimal voltage accuracy. Verify thermal management requirements, as power dissipation drops significantly above ambient temperatures of 75 °C.
Part Context
This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. Unlike the HE3_A variants, the E3 version is designated for commercial grade applications and lacks AEC-Q101 automotive qualification.
Replacement Considerations
Cross-reference with other manufacturers offering dual common cathode Zener arrays in SOT-23 packages. Verify matching electrical parameters such as Zener voltage tolerance, dynamic resistance, and maximum reverse leakage current to ensure circuit compatibility.
FAQ
Is the DZ23C30-E3-18 qualified for automotive applications?
No, the base P/N-E3 is designated as commercial grade. Automotive qualification requires the HE3_A variant which meets AEC-Q101 standards.
What is the dynamic resistance specification for this device?
The dynamic resistance (ZZ) is 80 Ω at the test current (Izt) of 2 mA, and 250 Ω at the knee current (Izk).
How many Zener diodes are contained in one package?
The device contains two individual Zener diodes arranged in a common cathode configuration within a single SOT-23 package.
