Overview
The Nexperia BZB784-C3V3-QX is a voltage regulator double diode housed in an SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 3.3 V with a tolerance of approximately ±5%. The device has a total power dissipation rating of 350 mW and operates within a temperature range of -55 °C to +150 °C. It includes two cathodes and one common anode, with a maximum forward voltage of 0.9 V at 10 mA. The component is qualified according to AEC-Q101 standards for automotive applications.
Feature Summary
- Dual-diode configuration with a common anode structure
- Qualified for automotive applications under AEC-Q101 standards
- Compact SC-70 plastic surface-mounted package design
Applications
- General regulation functions
- ESD protection
- Surge protection
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details. Ensure that the selected variant matches the required voltage tolerance and thermal characteristics for the intended circuit environment before finalizing procurement orders.
Selection Notes
Select this component when dual voltage regulation or protection is required in space-constrained designs. Verify that the 350 mW total power dissipation limit accommodates the expected load conditions across both diodes. Confirm compatibility with the SOT323 footprint during PCB layout planning.
Part Context
This part belongs to the BZB784-Q series of low-power voltage regulator double diodes manufactured by Nexperia. The series offers various nominal working voltages ranging from 2.4 V to 15 V, all sharing the same SOT323 package and automotive qualification profile for consistent integration into high-density circuit designs.
Replacement Considerations
Direct substitutes within the BZB784-Q series include BZB784-C3V0-QX and BZB784-C3V6-QX. These parts share identical pinning and package dimensions but differ in nominal Zener voltage. Verify that the alternative voltage ratings meet the specific circuit requirements before substitution.
