Overview
The Nexperia BZB784-C5V1-Q is a low-power voltage regulator double diode housed in a SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 5.1 V with a tolerance of approximately ±5%. The device has a total power dissipation of 350 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse current of 2 µA at VR = 2 V, a differential resistance of 40 Ω to 480 Ω, and a diode capacitance of 300 pF at f = 1 MHz. It is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Dual Zener diode configuration with common anode structure
- Automotive-grade qualification compliant with AEC-Q101 standards
- Compact SC-70 plastic surface-mount package design
Applications
- General regulation functions
- ESD protection circuits
- Surge protection applications
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape and reel specifications or cut tape availability. Ensure that the component meets the required AEC-Q101 qualification status for intended automotive deployment. Cross-reference the marking code '99' with the datasheet to validate authenticity upon receipt.
Selection Notes
Select this component when a dual voltage reference or protection solution is required in space-constrained designs. The SOT323 package supports high-density circuit layouts. Consider the 5.1 V nominal voltage and ±5% tolerance for precise regulation needs. Evaluate thermal constraints given the 350 mW power dissipation limit in free air conditions.
Part Context
This part belongs to the BZB784-Q series, which offers a comprehensive range of nominal working voltages from 2.4 V to 15 V. All variants share the same SOT323 package and AEC-Q101 qualification. The series provides customized protection solutions for small-scale, high-density electronic designs across various industrial and automotive sectors.
Replacement Considerations
Direct substitutes within the BZB784-Q series include BZB784-C4V7-Q and BZB784-C5V6-Q if voltage adjustments are permissible. Non-series replacements require matching the SOT323 footprint, 350 mW power rating, and AEC-Q101 qualification. Verify pinout compatibility and electrical parameters before substitution.
