Overview
The DZ23C7V5-G3-18 is a dual common cathode silicon planar Zener diode array from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It provides two independent Zener references with a nominal voltage of 7.5 V and a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a dynamic resistance of 7 Ω at a test current of 5 mA and a reverse leakage current of 0.1 μA maximum.
Feature Summary
- Dual common cathode configuration for compact circuit design
- Graded Zener voltages according to international E24 standards
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual stable potentials
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in low-power electronic assemblies
Procurement Notes
Verify the specific suffix '-18' against official documentation to confirm reel specifications and minimum order quantities. Ensure that the ordering code matches the required tape-and-reel dimensions before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel Zener solution is required in a minimal footprint. Confirm that the 7.5 V nominal voltage aligns with system requirements and that the ±5 % tolerance meets the precision needs of the application.
Part Context
This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage options in the SOT-23 package, providing designers with standardized components for voltage regulation and protection tasks across commercial electronics.
Replacement Considerations
Cross-reference with other DZ23-G series variants for different voltage ratings. Verify pinout compatibility and thermal characteristics when substituting with similar dual Zener arrays from other manufacturers.
