Overview
The Nexperia BZB784-C15-QX is a voltage regulator double diode housed in an SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 15 V with a tolerance of ±5%. The device has a total power dissipation of 350 mW and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum reverse current of 50 nA at VR = 10.5 V, a differential resistance of 200 Ω typ, and a capacitance of 30 pF max at f = 1 MHz. It is qualified according to AEC-Q101 for automotive applications.
Feature Summary
- Dual common-anode configuration in a compact SC-70 plastic package
- Automotive-grade qualification compliant with AEC-Q101 standards
- Approximately 5% working voltage tolerance across the E24 range
Applications
- General regulation functions
- ESD protection
- Surge protection
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as reel size or tape width. Confirm that the 'Q' designation aligns with the required automotive qualification level for your specific application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual-diode Zener solution is required in a small footprint. Ensure the 15 V breakdown voltage matches the circuit requirements and verify that the 350 mW power dissipation capability is sufficient for the expected thermal conditions on the PCB.
Part Context
This part belongs to the BZB784-Q series, which offers a comprehensive range of low-power voltage regulator double diodes. The series provides various nominal voltages from 2.4 V to 15 V, all sharing the same SOT323 package and automotive qualification profile for consistent design integration.
Replacement Considerations
Check for other parts within the BZB784-Q series with different voltage ratings if the 15 V specification does not match. Verify pinout compatibility with the SOT323 package before substituting with non-Nexperia equivalents.
