Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct tolerance and packaging specifications. Confirm that the SOT23 footprint matches the design requirements. Check for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a small SMD form factor. The C-series tolerance of approximately ±5 % suits general regulation needs. Ensure the application current remains within the specified limits to maintain the 300 mW total power dissipation rating without exceeding thermal constraints.

Part Context

This part belongs to the BZB84-Q series, which comprises 74 types covering nominal working voltages from 2.4 V to 75 V. The series includes both B (±2 %) and C (±5 %) tolerance variants. All devices share the same SOT23 plastic package dimensions and pinout, differing primarily in their Zener voltage characteristics and tolerance grades.

Replacement Considerations

Direct functional substitutes within the same series include BZB84-B16-QR for tighter tolerance requirements. Other BZB84-Q variants with different voltages may serve if the circuit design allows for voltage adjustment. Verify pin compatibility and thermal performance before substituting with components from other manufacturers.
