BZB984-C9V1,115

Overview

The Nexperia BZB984-C9V1,115 is a voltage regulator double diode housed in an SOT663 ultra-small plastic surface-mounted package. It features two independent cathodes and a common anode configuration. The nominal working voltage is 9.1 V with approximately 5% tolerance. Total power dissipation is rated at 425 mW for both diodes loaded and 265 mW for one diode loaded at 25 °C. The device supports a junction temperature up to 150 °C and operates within an ambient temperature range of -55 °C to +150 °C. Non-repetitive peak reverse current is specified at 150 A for a 100 µs pulse.

Procurement Notes

Verify the specific ordering suffix matches the required packaging format before purchase. Confirm that the application environment remains within the specified thermal limits to ensure reliable operation. Check the latest datasheet revision for any updates to mechanical dimensions or electrical characteristics prior to finalizing the bill of materials.

Selection Notes

Select this component when dual voltage reference points are needed in a minimal footprint. Ensure the load current does not exceed the maximum forward current rating. Consider the thermal resistance values when designing PCB copper areas for adequate heat dissipation under continuous load conditions.

Part Context

This part belongs to the BZB984 series of low-power voltage regulator double diodes. The series offers nominal working voltages ranging from 2.4 V to 15 V. All variants share the same SOT663 package and pinout configuration, differing primarily in their Zener breakdown voltage specifications.

Replacement Considerations

Other parts within the BZB984 series (e.g., BZB984-C8V2, BZB984-C10) serve as direct functional substitutes if different voltage ratings are acceptable. Verify that alternative components match the SOT663 package outline and pin assignment to maintain board compatibility.
