BZX38450-C3V9-QX is listed in the Single Zener Diodes range at ChipApex. The manufacturer field lists Nexperia USA Inc.. Its product description is DIODE ZENER 3.9V 300MW SOD323. Review the specifications below when checking this part for your BOM.
The Nexperia BZX38450-C3V9-QX is a low-current voltage regulator diode in the SOD323 (SC-76) surface-mount package. It features a nominal Zener voltage of 3.9 V with ±5% tolerance, specified at a test current of 50 µA. The device supports a total power dissipation of up to 300 mW and operates within an ambient temperature range of -55 °C to +150 °C. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a differential resistance of 95 Ω at 1 mA, and a reverse leakage current of 2.5 µA at 5 mA.
Verify the specific suffix 'QX' against official Nexperia documentation to confirm packaging details and reel specifications. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference the marking code '6Z' on the physical device to validate authenticity and correct voltage rating before integration into production circuits.
Select this component when designing circuits requiring precise low-voltage regulation under minimal bias conditions. The SOD323 package offers space efficiency for compact layouts. Consider the thermal resistance characteristics and operating temperature limits to ensure reliability in high-temperature environments or constrained PCB footprints.
This part belongs to the BZX38450-Q series, which provides low-current voltage regulation in a small plastic surface-mounted package. The series covers nominal working voltages from 1.8 V to 51 V, offering flexibility for various reference and protection needs in modern electronic systems.
Direct substitutes within the same series include BZX38450-B3V9-QX for tighter tolerance requirements.
