Procurement Notes
Verify the specific package suffix 'A' corresponds to the E-Line 3-pin configuration with Pin 1 floating or connected to Pin 3. Confirm tolerance level matches the '03' designation for ±3% accuracy. Ensure operating conditions remain within the specified 20μA to 5mA range for optimal performance. Check datasheet for absolute maximum ratings regarding reverse and forward currents.
Selection Notes
Select this component when space-saving through-hole packaging is required alongside precision voltage referencing. The E-Line 3-pin package suits designs needing robust transient handling. Consider the low knee current for ultra-low power standby modes. Verify thermal dissipation limits if ambient temperatures approach the upper operational boundary.
Part Context
The ZRC330 series includes variants in SOT23, SO8, and E-Line packages with tolerances of 1%, 2%, and 3%. The ZRC330A03 specifically denotes the 3% tolerance version in the standard E-Line 3-pin format. Other suffixes like 'F' indicate surface mount options, while 'N8' refers to SO8 packaging.
Replacement Considerations
ZRC330A02 (2% tolerance), ZRC330A01 (1% tolerance). ZXRE330AV-A (TO92-3, 0.5% tolerance). ZXRE330ESA-13 (SOT-23-3, 2% tolerance). ZXRE330EV-A (TO-92, 2% tolerance).
