ZNBG4001Q16TC

Overview

The ZNBG4001Q16TC is a fixed bias generator integrated circuit manufactured by Diodes Incorporated. It operates within a supply voltage range of 5V to 12V and draws a maximum supply current of 50mA. The device is designed for surface-mount installation in a 16-QSOP package, measuring 3.90mm in width. It supports an operating temperature range from -40°C to 70°C. This component functions as a dedicated power management IC, providing stable bias currents for connected circuits.

Feature Summary

• Provides stable current supply for biasing applications
• Operates efficiently across a wide industrial temperature range
• Supports standard voltage supply inputs between 5V and 12V

Applications

• Bias controller circuits
• Power management systems requiring fixed bias generation
• Electronic devices needing stable reference currents

Procurement Notes

Verify the exact suffix designation when sourcing replacements, as variations may indicate different packaging or tape-and-reel configurations. Confirm that the obsolete status does not impact long-term availability requirements. Ensure the 16-QSOP footprint matches the target PCB design. Check for RoHS3 compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed bias generator is required for PMIC applications. The 16-QSOP package suits space-constrained surface-mount designs. Verify that the 5V-12V input range aligns with the system power rails. Consider the -40°C to 70°C operating range for environmental compatibility. The 50mA supply current limit should be evaluated against total system power budgets.

Part Context

This part belongs to the ZNBG4001 series of bias controllers from Diodes Incorporated. It serves as a specialized power management solution for generating consistent bias currents. The Q16 suffix typically denotes the specific 16-pin QSOP package variant. It is distinct from other series members by its fixed output characteristics and package configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component status is listed as obsolete. Users must verify pinout and electrical specifications carefully when selecting alternative components from other manufacturers.
