Overview
The DZ23C15-HE3-18 is a dual Zener diode array manufactured by Vishay General Semiconductor. It features a common cathode configuration within an SOT-23-3 surface-mount package. The nominal Zener voltage is 15 V with a tolerance of ±5%. The device has a maximum power dissipation of 300 mW and operates over a junction temperature range of -55°C to 150°C.
Feature Summary
- Dual Zener diodes integrated in a single compact SOT-23-3 package
- Common cathode configuration for simplified circuit design
- High thermal stability suitable for wide operating temperature ranges
Applications
- Voltage reference circuits requiring dual stable potentials
- Over-voltage protection for sensitive signal lines
- Clamping applications in portable electronic devices
Procurement Notes
Verify the specific ordering suffix (e.g., -18 for tape and reel) against the required packaging format. Confirm that the common cathode configuration aligns with the schematic requirements. Ensure the 15V Zener voltage and 300mW power rating meet the thermal and electrical constraints of the target application environment.
Selection Notes
Select this component when space-constrained designs require two independent Zener references or clamping functions. The SOT-23-3 footprint offers a small solution size compared to discrete components. Consider the ±5% voltage tolerance for precision requirements and verify that the common cathode topology matches the intended biasing scheme.
Part Context
This part belongs to the DZ23 series of dual Zener arrays from Vishay. These components are designed to replace multiple discrete diodes, reducing board space and assembly complexity. The series includes various voltage options and configurations to support diverse voltage regulation and protection needs in consumer and industrial electronics.
Replacement Considerations
Cross-reference with other DZ23 series variants for different voltage ratings. Verify pinout compatibility with alternative manufacturers' dual Zener arrays in the SOT-23-3 package before substitution.
