Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm that the ordering suffix "-TP" indicates tape and reel packaging containing 3000 pieces per reel. Ensure the specific part number matches the required 130 V specification before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 5 W power dissipation capability is required for high-voltage regulation. The DO-214AA package suits space-constrained surface mount designs. Verify thermal management requirements against the specified thermal resistance values to ensure reliable operation within the stated temperature limits.

Single Zener Diodes Part Context

This component belongs to the SMBJ5338B through SMBJ5388B series of 5.0 W surface mount Zener diodes. The series covers a wide voltage range from 5.1 V to 200 V. All devices in this family share identical physical dimensions and thermal characteristics while differing in their specific breakdown voltage ratings.
