Procurement Notes
Verify authenticity through authorized MCC distributors or direct procurement channels to avoid counterfeit components. Confirm that the ordering suffix indicates RoHS compliance and tape-and-reel packaging. Ensure the specific part number matches the required voltage marking code before finalizing orders.
Selection Notes
Select this component when a compact dual Zener solution is required for automotive or industrial environments. The tight voltage matching between the two internal diodes makes it suitable for differential signaling or balanced protection circuits. Verify thermal management requirements against the specified thermal resistance value.
Part Context
This component belongs to the DZ23C series of 300 mW Zener diodes offered by Micro Commercial Components. The series covers a wide voltage spectrum from 2.4 V to 47 V, all housed in the SOT-23 surface-mount package. The HE3 designation signifies Halogen-free Epoxy, aligning with environmental regulations.
Replacement Considerations
Direct substitutes include other DZ23C12 variants such as DZ23C12-TP if automotive qualification is not mandatory. Cross-reference with other manufacturers offering dual common cathode Zeners in SOT-23 packages, ensuring identical pinout and electrical parameters are maintained.
